I like it. I wanted to cycle through a bunch of games. I added a player, so essentially 2 players. The animation of confetti slows it down something awful on my machine though.

If someone wants to cycle through games very quickly maybe giving them an option to disable anything that might slow it down.

For someone trying to learn the math quickly and look at the odds, being able to cycle through each game and aspect of the game might be the most important thing.

I'd make an option that's as barebones and quick as possible.
