Very nice implementation of Liar's Dice - but with shapes! I took that snarky Rex down a peg or two (after a couple attempts). I'll confess I'm not so good at this variation - when you win, you gain an advantage in knowledge (you have more dice on the table) but the bets are all still on all the dice on the table, so there is no material advantage.
I'm curious how you coded the betting/bluffing logic? Rex seemed to ground his bluffs on what he truly had, and he saw through a lot of mine tbh.
