Is there any variation or end to the game? At some point, at some score, does the difficulty increase, does the environment change, is there ever an end to it?

One variation I really like is - exactly like the original, but with many, many players in there at once. – Rory Alsop Feb 19 '14 at 10:56
I discovered Maverick Bird a few days ago. It's (presumably) endless, but right from the start it has unique and random obstacles. – Kendall Frey Feb 21 '14 at 13:01
Although I was asking about variations inside the game itself, I do appreciate your links, @KendallFrey. – Siddhartha Feb 22 '14 at 5:59

The gameplay never changes.

Videos like this one are fake:

Then that's some damn good editing/coding (probably the latter). – Siddhartha Feb 19 '14 at 10:03
Since the game was written in Java, it wouldn't be too hard to decompile it, modify it, and recompile it. It would be even easier if the game was written in some script parsed by an engine instead. – Thebluefish Feb 19 '14 at 12:34
@Siddhartha it's a video editing channel. It was an ad-hoc work. – badp Feb 19 '14 at 15:37

As Strix says in his comments, the probability of each pipe is considered independently. Take a coin toss as an example:

Suppose that we have just tossed four heads in a row, so that if the next coin toss were also to come up heads, it would complete a run of five successive heads. Since the probability of a run of five successive heads is only 1⁄32 (one in thirty-two), a person subject to the gambler's fallacy might believe that this next flip was less likely to be heads than to be tails. However, this is not correct, and is a manifestation of the gambler's fallacy; the event of 5 heads in a row and the event of "first 4 heads, then a tails" are equally likely, each having probability 1⁄32. Given that the first four rolls turn up heads, the probability that the next toss is a head is in fact, 1/2.


The game only becomes increasingly difficult due to player fatigue etc.

You appear to be quoting from somewhere about the gambler's fallacy, care to add a link or reference from where you are quoting? – ken.ganong Feb 19 '14 at 16:07

No, the game does not increase game-wise.

It does, however, get more difficult. This is not because the game itself is getting more difficult, but because the longer you play, the higher the probability that you will make a mistake.

This is called difficulty through duration.

You are no more likely to make a mistake after playing for 10 minutes than you are when you first start. The difference is that you have had more opportunities to make mistakes, which makes it more likely that you would have made a mistake to this point. The actual likelihood for mistakes at each set of pipes is static. – StrixVaria Feb 19 '14 at 14:52
If you have a 90% chance of passing a set of pipes, then the chance that you pass 5 pipes is (.9)^5 or ~59%, but if you have already passed 5 pipes and need to pass one more pipe, the chance for that pipe is still 90%. The game does not get more difficult. – StrixVaria Feb 19 '14 at 14:58
I think the way you worded, "the longer you play, the higher the probability that you will make a mistake" implies that that player has a higher chance of making a mistake the longer he plays. You might want to make a distinction between total gameplay and individual challenges. – Frank Feb 19 '14 at 15:02
The user has a higher probability of having made a mistake, but not a higher probability of making a new mistake. – StrixVaria Feb 19 '14 at 15:05
Did I accidentally open up ? – Zibbobz Feb 19 '14 at 15:08
