Why is Puzzle Bobble easier than Bust-A-Move?

I've wanted to write a tribute piece to Bust-A-Move for a while. I couldn't come up with the right premise for it. I don't write especially good game reviews. I could write about being probably the only person on earth who pre-ordered the Super Nintendo version. I only played it a couple times in the arcade but it was an instant favorite. I worked at a video game store at the time and knew a Super Nintendo port was coming. I also knew we'd only receive a couple copies because it wasn't a major release. Pre-orders were kind of a new concept then, and it was unnecessary for me to pre-order since I'd be the one unpacking the UPS box. That didn't stop me.

Bust-A-Move would go on to be one of my most-played Super Nintendo games. It's still a great way to unwind.

I bought it on the Switch also of course, it was somewhere around $5-$7 at the time. It included Puzzle Bobble, the original version in Japanese. I assumed these were the exact same game, minus the name & title.

Puzzle Bobble: Title
Bust-A-Move: Title

I tried Puzzle Bobble and found it was much easier than Bust-A-Move. The first time I played the single-player versus mode I went through the whole thing undefeated. It never felt like the CPU AI was trying. Then in the challenge mode the wildcard bubble, that eliminates every bubble of whichever color you hit, appeared. This bubble is not in Bust-A-Move.

Puzzle Bobble: Undefeated vs CPU
Puzzle Bobble: Challenge

I checked the option screen in both versions. They each start at the middle of three difficulty options.

Puzzle Bobble: Default options
Bust-A-Move: Default options

It's a little confusing because in Bust-A-Move "Normal" is used for both "Levels" and "Levels of computer". While in Puzzle Bobble they use different values for each. They instead went with "Normal" and "Medium". In my extremely limited understanding, the latter is used when describing the strength of something (such as a computer opponent). Like in English a person could be described as "burly" but it wouldn't make sense to say a level has "burly" difficulty. The translator decided to simplify the English options which I think was the right call.

When I started the story mode (I know it's not called that) it also seemed easier. I couldn't pinpoint why though.

I'm going to solve it the only way I know how... by comparing these games stage-by-stage. From here on out, Puzzle Bobble is on the left and Bust-A-Move is on the right.

Stage 1

Puzzle Bobble: Stage 01
Bust-A-Move: Stage 01

The tutorial stage is the same.

Stage 2

Puzzle Bobble: Stage 02
Bust-A-Move: Stage 02

OK, this didn't take long to sort out. Stage 2 in Puzzle Bobble is one row shorter than Bust-A-Move.

Does the difficulty setting effect anything here? First, here is Puzzle Bobble stage 2 on the difficult setting:

Puzzle Bobble: Difficult option
Puzzle Bobble: Stage 2 - difficult

The layout is unchanged. Likewise with Bust-A-Move set to easy difficulty:

Bust-A-Move: Easy option
Bust-A-Move: Stage 2 - easy

So that's it, the layout in Puzzle Bobble is just plain easier. We only had to get to the second stage to find a difference. That means it is officially worth comparing the rest of the stages because there must be more like it.

Stage 3

Puzzle Bobble: Stage 03
Bust-A-Move: Stage 03

This looks the same. There isn't much that would make this stage easier anyway.

Stage 4

Puzzle Bobble: Stage 04
Bust-A-Move: Stage 04

I am assuming that anyone reading this is familiar with how Puzzle Bobble/Bust-A-Move works. So in stage 4 it's obvious why Puzzle Bobble is easier. A single orange bubble can clear the entire board. Until that bubble arrives, it is easy to clear most of the board with a blue or gray bubble. In Bust-A-Move, two orange bubbles are needed and the blue bubbles are a more difficult shot.

Stage 5

Puzzle Bobble: Stage 05
Bust-A-Move: Stage 05

These are the same and again it's a very easy stage. This stage exists to show how the thunderbolt bubbles work.

Stage 6

Puzzle Bobble: Stage 06
Bust-A-Move: Stage 06

There are no differences here, this is another simple stage.

Stage 7

Puzzle Bobble: Stage 07
Bust-A-Move: Stage 07

Puzzle Bobble is easier because those top orange and purple bubbles are both a clear shot. The blue and green bubbles are also easier to hit.

Stage 8

Puzzle Bobble: Stage 08
Bust-A-Move: Stage 08

I had to go back a replay this level to make sure I didn't get it wrong. Nope, the Puzzle Bobble stage is actually half the size of Bust-A-Move. It doesn't even matter, it's the difference of finishing the stage in one shot or two.

Stage 9

Puzzle Bobble: Stage 09
Bust-A-Move: Stage 09

Bust-A-Move includes those three extra gray bubbles. That is a small change with a big impact to the difficulty. It means gray bubbles will spawn until they are cleared. At the start of the stage there is no good place to shoot a gray bubble. In Puzzle Bobble you will always spawn bubbles that have a matching color open.

Stage 10

Puzzle Bobble: Stage 10
Bust-A-Move: Stage 10

In this stage, Puzzle Bobble has one more bubble than Bust-A-Move but it makes the stage easier.

Stage 11

Puzzle Bobble: Stage 11
Bust-A-Move: Stage 11

This is the first (but not only) stage with a different fundamental layout. In Puzzle Bobble, half the stage can be cleared on the first shot. In Bust-A-Move, by the time you clear a path to a thunderbolt bubble it is practically useless.

Stage 12

Puzzle Bobble: Stage 12
Bust-A-Move: Stage 12

These are the same, once again for a very simple level.

Stage 13

Puzzle Bobble: Stage 13
Bust-A-Move: Stage 13

This is an odd one. Puzzle Bobble starts with more colors, which usually makes a level more difficult. However, breaking the gray bubbles drops all the rows below them. Bust-A-Move is a little more complicated despite starting with fewer colors to eliminate.

Stage 14

Puzzle Bobble: Stage 14
Bust-A-Move: Stage 14

I don't think the differences here impact the difficulty. This is an easy enough stage in either version.

Stage 15

Puzzle Bobble: Stage 15
Bust-A-Move: Stage 15

There is a very subtle difference that makes Puzzle Bobble easier here. In Bust-A-Move red, purple, and green bubbles are useless and annoying until the bottom two rows are cleared. In Puzzle Bobble there is at least a place for red bubbles that isn't useless. They are still annoying until those rows are cleared.

Stage 16

Puzzle Bobble: Stage 16
Bust-A-Move: Stage 16

This is a throwback to stage 2 where Puzzle Bobble has fewer rows.

Stage 17

Puzzle Bobble: Stage 17
Bust-A-Move: Stage 17

These are the same, again for a stage that can be cleared easily.

Stage 18

Puzzle Bobble: Stage 18
Bust-A-Move: Stage 18

This is the most challenging level so far where the layouts are identical.

Stage 19

Puzzle Bobble: Stage 19
Bust-A-Move: Stage 19

This is an easy level, it's just a couple simple bank shots to clear.

Stage 20

Puzzle Bobble: Stage 20
Bust-A-Move: Stage 20

This is another extremely simple stage. You can often finish it without moving the pointer.

Stage 21

Puzzle Bobble: Stage 21
Bust-A-Move: Stage 21

Puzzle Bobble is slightly easier because it starts with fewer colors.

Stage 22

Puzzle Bobble: Stage 22
Bust-A-Move: Stage 22

Wow, this is an unnecessarily easy stage in Puzzle Bobble. The Bust-A-Move version is not challenging. The Puzzle Bobble version starts with fewer colors and those two sets of three red bubbles make the stage even easier.

Stage 23

Puzzle Bobble: Stage 23
Bust-A-Move: Stage 23

This is another one where subtle differences greatly impact the difficulty. In Puzzle Bobble, the rightmost set of bubbles have yellow and blue sections ready to burst. This clears access to the next section quickly. The two purple ones in Bust-A-Move do not clear as much space.

Stage 24

Puzzle Bobble: Stage 24
Bust-A-Move: Stage 24

In this stage, Puzzle Bobble has fewer bubbles and a clear path to the two waterfall bubbles.

Stage 25

Puzzle Bobble: Stage 25
Bust-A-Move: Stage 25

This is a little bit of a mixed bag. Puzzle Bobble starts with more colors but has a third thunderbolt bubble. These are about equal difficultly in the end.

Stage 26

Puzzle Bobble: Stage 26
Bust-A-Move: Stage 26

Another stage where the layout is the same and the difficultly is at least average.

Stage 27

Puzzle Bobble: Stage 27
Bust-A-Move: Stage 27

I had to double-check these weren't reversed. I think this is the first stage so far where Bust-A-Move is easier. The third from the bottom row in particular. The middle section though, Puzzle Bobble is slightly easier. Once the top two rows are reached it's back to Bust-A-Move being easier.

Stage 28

Puzzle Bobble: Stage 28
Bust-A-Move: Stage 28

This is another one I had to double-check, I thought I had mistakenly cleared a section in Puzzle Bobble before taking the screenshot. Nope. It has a much easier path to reaching the exploding bubble from the start.

Stage 29

Puzzle Bobble: Stage 29
Bust-A-Move: Stage 29

This is another stage where Bust-A-Move is slightly easier because it has those two orange bubbles that are close at the start of the stage. It's not a huge difference though.

Stage 30

Puzzle Bobble: Stage 30
Bust-A-Move: Stage 30

Puzzle Bobble is obviously much easier here, especially the center column.

Stage 31

Puzzle Bobble: Stage 31
Bust-A-Move: Stage 31

These start off the same, but once the thunderbolt bubbles are reached Puzzle Bobble becomes the easier of the two.

Stage 32

Puzzle Bobble: Stage 32
Bust-A-Move: Stage 32

This is my least favorite level in the game, the only one I outright dislike. If you don't get an orange bubble in the first 4-5 that's it. There is no difference in these versions.

Stage 33

Puzzle Bobble: Stage 33
Bust-A-Move: Stage 33

This is another fairly challenging level that is the same in both versions.

Stage 34

Puzzle Bobble: Stage 34
Bust-A-Move: Stage 34

Another one that is the same in both versions. This level is either really easy or really tough depending on the random order of bubbles to shoot.

Stage 35

Puzzle Bobble: Stage 35
Bust-A-Move: Stage 35

Another level that is the same, it is a deceptively easy one though.

Stage 36

Puzzle Bobble: Stage 36
Bust-A-Move: Stage 36

OK, back to a stage where Puzzle Bobble is clearly easier because it starts with fewer colors.

Stage 37

Puzzle Bobble: Stage 37
Bust-A-Move: Stage 37

The differences here are small and I don't think matter either way.

Stage 38

Puzzle Bobble: Stage 38
Bust-A-Move: Stage 38

This begins a block of three stages that are the same and also easy.

Stage 39

Puzzle Bobble: Stage 39
Bust-A-Move: Stage 39

This level is only challenging if a lot of green bubbles spawn early.

Stage 40

Puzzle Bobble: Stage 40
Bust-A-Move: Stage 40

This is just a level where the designers had some fun. It takes about 2 seconds to clear.

Stage 41

Puzzle Bobble: Stage 41
Bust-A-Move: Stage 41

The rainbow bubbles are easy to hit from the beginning of the stage in Puzzle Bobble. By the time you clear them in Bust-A-Move they are not helpful.

Stage 42

Puzzle Bobble: Stage 42
Bust-A-Move: Stage 42

The Puzzle Bobble version is easier if you start with a blue or gray bubble in the queue.

Stage 43

Puzzle Bobble: Stage 43
Bust-A-Move: Stage 43

Puzzle Bobble has fewer bubbles but isn't that much easier otherwise.

Stage 44

Puzzle Bobble: Stage 44
Bust-A-Move: Stage 44

Puzzle Bobble has four colors while Bust-A-Move has a whopping seven by comparison.

Stage 45

Puzzle Bobble: Stage 45
Bust-A-Move: Stage 45

This looks the same on both versions. There's not any strategy to this level, it relies on good random luck.

Stage 46

Puzzle Bobble: Stage 46
Bust-A-Move: Stage 46

Depending on what I count, this is the second or third level where Puzzle Bobble is possibly more difficult than Bust-A-Move. There are more bubbles but the waterfall is easier to hit.

Stage 47

Puzzle Bobble: Stage 47
Bust-A-Move: Stage 47

This one is the same on both, and another level that relies heavily on luck.

Stage 48

Puzzle Bobble: Stage 48
Bust-A-Move: Stage 48

The bubbles are different colors but I don't see anything making one easier than the other.

Stage 49

Puzzle Bobble: Stage 49
Bust-A-Move: Stage 49

So I'm beginning to wonder if Puzzle Bobble starts off easier than grows more difficult? It's not like I'll be proven wrong in literally the next stage or anything.

Stage 50

Puzzle Bobble: Stage 50
Bust-A-Move: Stage 50

Alright, halfway mark. I thought I'd run out of steam by now by now but I'm going strong. Also so much for that theory. The addition of orange bubbles makes Bust-A-Move the more difficult version of stage 50.

Stage 51

Puzzle Bobble: Stage 51
Bust-A-Move: Stage 51

I was about to declare that Puzzle Bobble is the more difficult version then noticed Bust-A-Move starts with one more color. To make it worse, the gray bubbles are buried so starting with several gray bubbles is going to wreck you.

Stage 52

Puzzle Bobble: Stage 52
Bust-A-Move: Stage 52

These stages are the same.

Stage 53

Puzzle Bobble: Stage 53
Bust-A-Move: Stage 53

This is another fun and easy stage with no differences between the two versions.

Stage 54

Puzzle Bobble: Stage 54
Bust-A-Move: Stage 54

This one is kind of a wash too. Puzzle Bobble starts off with a blue, red, and green pair. Bust-A-Move has more pairings but they are only two colors. Either way this depends on which bubbles spawn.

Stage 55

Puzzle Bobble: Stage 55
Bust-A-Move: Stage 55

This is four colors vs. five colors, fewer colors is always easier.

Stage 56

Puzzle Bobble: Stage 56
Bust-A-Move: Stage 56

It's possible that Puzzle Bobble is maybe a little bit easier. It is for sure if you are lucky enough to start with a yellow bubble, like in this screenshot, and are able to just thread it on the left side. Bust-A-Move has the purple bubbles on the left that are a couple rows lower.

Stage 57

Puzzle Bobble: Stage 57
Bust-A-Move: Stage 57

I double-checked this one too, the layout for Puzzle Bobble is so odd. Your first two shots will clear about half the board.

Stage 58

Puzzle Bobble: Stage 58
Bust-A-Move: Stage 58

We're getting into another block of identical stages. This one reminds me of Boxing on the Atari 2600.

Stage 59

Puzzle Bobble: Stage 59
Bust-A-Move: Stage 59

This is another stage where you need good random luck.

Stage 60

Puzzle Bobble: Stage 60
Bust-A-Move: Stage 60

This stage is a pain if you get orange, red, yellow, or gray bubbles early.

Stage 61

Puzzle Bobble: Stage 61
Bust-A-Move: Stage 61

These layout are different they are hard to compare. With Bust-A-Move you can clear a lot of the board with a well placed purple bubble. For Puzzle Bobble, this stage is a grind. Actually on further inspection, stages 61 and 92 are flipped. So on Puzzle Bobble you're seeing the more difficult stage first.

Stage 62

Puzzle Bobble: Stage 62
Bust-A-Move: Stage 62

These are the same again.

Stage 63

Puzzle Bobble: Stage 63
Bust-A-Move: Stage 63

And... also the same.

Stage 64

Puzzle Bobble: Stage 64
Bust-A-Move: Stage 64

The Puzzle Bobble version is so much easier here. It starts with fewer colors, which always helps. It's also possible to knock down big sections more easily.

Stage 65

Puzzle Bobble: Stage 65
Bust-A-Move: Stage 65

These are the same.

Stage 66

Puzzle Bobble: Stage 66
Bust-A-Move: Stage 66

These are also the same.

Stage 67

Puzzle Bobble: Stage 67
Bust-A-Move: Stage 67

Here Puzzle Bobble is easier because it starts with one fewer color.

Stage 68

Puzzle Bobble: Stage 68
Bust-A-Move: Stage 68

Now we're getting to another small block of stages that are the same. These are all fun, artistic stages. These are the kinds of shapes in early Picross games.

Stage 69

Puzzle Bobble: Stage 69
Bust-A-Move: Stage 69

I assume these are supposed to be hourglasses.

Stage 70

Puzzle Bobble: Stage 70
Bust-A-Move: Stage 70

Maybe these are a character (meaning Kanji, not a cartoon character).

Stage 71

Puzzle Bobble: Stage 71
Bust-A-Move: Stage 71

Here's the last same stage one for a little bit.

Stage 72

Puzzle Bobble: Stage 72
Bust-A-Move: Stage 72

The difference here is Puzzle Bobble starts with one fewer color again.

Stage 73

Puzzle Bobble: Stage 73
Bust-A-Move: Stage 73

On this stage, Bust-A-Move has some extra bubbles near the top that add just a little difficulty.

Stage 74

Puzzle Bobble: Stage 74
Bust-A-Move: Stage 74

The two lower clusters have fewer bubbles in Puzzle Bobble.

Stage 75

Puzzle Bobble: Stage 75
Bust-A-Move: Stage 75

This stage is the same on both, it's another one where you need some luck to get through.

Stage 76

Puzzle Bobble: Stage 76
Bust-A-Move: Stage 76

This one is also the same on both.

Stage 77

Puzzle Bobble: Stage 77
Bust-A-Move: Stage 77

This is another stage where Puzzle Bobble starts with four colors while Bust-A-Move starts with five.

Stage 78

Puzzle Bobble: Stage 78
Bust-A-Move: Stage 78

These stages are not close at all. Despite being densely packed, Puzzle Bobble is way easier because of the four fireball bubbles.

Stage 79

Puzzle Bobble: Stage 79
Bust-A-Move: Stage 79

Stages 79 and 84 are flipped. Puzzle Bobble stage 79 is identical to Bust-A-Move stage 84. Bust-A-Move stage 79 is the same layout as Puzzle Bobble stage 84 but with more starting colors.

Stage 80

Puzzle Bobble: Stage 80
Bust-A-Move: Stage 80

This tribute to Taito's early days is the same on both versions.

Stage 81

Puzzle Bobble: Stage 81
Bust-A-Move: Stage 81

This is another stage where Bust-A-Move starts with more colors. Bust-A-Move also removes the two center green bubbles that can never be hit anyway.

Stage 82

Puzzle Bobble: Stage 82
Bust-A-Move: Stage 82

These levels are the same.

Stage 83

Puzzle Bobble: Stage 83
Bust-A-Move: Stage 83

These levels are also the same.

Stage 84

Puzzle Bobble: Stage 84
Bust-A-Move: Stage 84

(See stage 79)

Stage 85

Puzzle Bobble: Stage 85
Bust-A-Move: Stage 85

From here on out there are not many differences. The next set of levels is challenging on Puzzle Bobble and they didn't crank many of them up for Bust-A-Move.

Stage 86

Puzzle Bobble: Stage 86
Bust-A-Move: Stage 86

I'm pretty sure this snail is in a Picross game.

Stage 87

Puzzle Bobble: Stage 87
Bust-A-Move: Stage 87

There's a small layout change that makes Puzzle Bobble easier. Well two now that I look again. The green bubble in the lower right side is exposed, and there's one less red bubble.

Stage 88

Puzzle Bobble: Stage 88
Bust-A-Move: Stage 88

Yeah, OK, technically Bust-A-Move is more difficult here. The additions are two matched pairs of bubbles though, so they're just a small extra bit of work.

Stage 89

Puzzle Bobble: Stage 89
Bust-A-Move: Stage 89

These are the same.

Stage 90

Puzzle Bobble: Stage 90
Bust-A-Move: Stage 90

Alright, home stretch. Bust-A-Move has a few more bubbles along the bottom making it the more difficult version. The yellow bubble in the top right corner gives it a sharper look but doesn't make things easier or harder.

Stage 91

Puzzle Bobble: Stage 91
Bust-A-Move: Stage 91

These are the same.

Stage 92

Puzzle Bobble: Stage 92
Bust-A-Move: Stage 92

Oh, I have to revise a previous entry now... see stage 61 for comments.

Stage 93

Puzzle Bobble: Stage 93
Bust-A-Move: Stage 93

These are the same general idea. There's no real difficulty difference.

Stage 94

Puzzle Bobble: Stage 94
Bust-A-Move: Stage 94

This does not look like another swapped level thing. The Puzzle Bobble stage starts with so many pairs already on the board. It's very easy for late in the game. The Bust-A-Move level is a tough one.

Stage 95

Puzzle Bobble: Stage 95
Bust-A-Move: Stage 95

The top section of this board is easier to clear out in Puzzle Bobble.

Stage 96

Puzzle Bobble: Stage 96
Bust-A-Move: Stage 96

This is almost a repeat of stage 45. Puzzle Bobble starts off with one less color.

Stage 97

Puzzle Bobble: Stage 97
Bust-A-Move: Stage 97

Here's a great stage to completely wreck you when you think you're almost at the end. It's the same layout in both versions.

Stage 98

Puzzle Bobble: Stage 98
Bust-A-Move: Stage 98

Puzzle Bobble has a much cleaner path to hitting the exploding bubble.

Stage 99

Puzzle Bobble: Stage 99
Bust-A-Move: Stage 99

This is a very fitting final regular stage. It is the same in both versions.

Stage 100

Puzzle Bobble: Stage 100
Bust-A-Move: Stage 100

I couldn't see any differences in the final boss fight.

So to finally answer the question in the title of this article... Puzzle Bobble is easier than Bust-A-Move because:

  1. The CPU AI has a lower default starting point than Bust-A-Move.
  2. The challenge mode includes the wildcard bubble not found in Bust-A-Move.
  3. The puzzle mode is typically easier because of fewer starting colors and small layout differences.

I won't speculate why the US release was made more difficult. There could be a dozen reasons or maybe none at all.
