Thank you for review! I thought about other pieces, but the only games I have remembered is bingo and coin flip (that wasn't implemented because of lack of ideas for them). Any other games is using cards (Uno, Set) or wasn't bound on random (Pool). UI/UX now is a very difficult thing for me and maybe in other games I'll make a better interface design and tooltips
I've now made over a half dozen games using Godot, and UI/UX is still the bane of my existence. I doff my hat to anyone in the industry that excels at it.
Other games with numeric tokens that I could think of:
Mahjong - although the set of possible values might overwhelm the other systems.
Billiard balls - Interesting if you could have a binary mod, which acts one way for stripped values and another way for solid values.
Coins and/or othello pieces - their binary nature could lend itself to very simple rule sets, but if you don't restrict yourself to just one set of coins, then you could have intersecting binary rulesets (eg: pennies do one thing based on facing, but silver dollars do something different based on facing)
Also, there have been a couple games based on the I Ching, and I believe one of the ways you can represent that is a set of three coins - although that one might be a stretch as the I Ching is more rarely used for games.
