Card Players
Counting, signalling, and the memory of what has already been played.
Card-game strength is one part probability, one part signalling, and one part working memory · what has been played, what is still out, what your partner just told you with a small tempo choice.

Why these games
Math is the card-counting and odds-arithmetic drill. Memory Game keeps the played-card buffer warm. Odds is the explicit probability-feel drill that turns "I think this is good" into a number.
