Nice little game!

i think this is a neat concept! i like the idea of risk and reward using only numbers and math. i do think it is a little easy, though, since you can just keep sending the same number and wait several beats to consider the next card. perhaps, every beat, you could shuffle the cards and add new ones in?

Nice work, but it seems to be lacking in gameplay. This could be a fine educational game, though.

Very interesting concept! I love math puzzles and like dealing with the number theory and this seemed especially related to the Collatz series which I like a lot.

One criticism I have is that there's no backspace button, so some big number turned out to be divisible by 3 and then you're destroyed and can't do anything about it. I strategized with pen and paper around the number 4 as the input and managed to beat the game that way.

@snowdozer I'm consider adding more path or something. But random the cards will make the game totally random and not playable, though it's really random now because player can only consider few cards.

@gentel I think 1/3 numbers can be divided by 3, but too many node totally become chaos in my brain. I just add some random nodes and test random inputs, and sometimes I get very large number.
