If a player has an ace in their hand, they can exchange up to 4 cards instead. Once every player has checked, called, raised, or folded, each player can give up to 3 cards from their hand to the dealer in exchange for new face-down cards from the deck. Alternatively, if player 2 raises, then the bet increases for each subsequent player, and player 1 must add the difference between their initial bet and the raised bet to the pot. If player 2 calls, the bet stays the same, and player 3 then must either call, raise, or fold. Then, the player to their left, player 2, can do one of four things: check (unless player 1 bet, in which case player 2 must bet to stay in that round), call (match the bet in the pot), raise (bet more than the player before them), or fold (forfeit that round).

Each player looks at their hand, and the player to the left of the dealer, player 1, can either check (bet nothing) or bet by putting money or chips into the pot. Then, the dealer deals everyone 5 cards face down, one at a time. To play, first each player puts a predetermined ante into the pot, like 10 dollars. Remember, if a running function instance calls another function, the former stays in memory waiting for the latter to end so it can resume from where it left off - there's a limit to how many function calls you can have active at once! See this guide re implementing some proper while / for loops.Five-Card Draw is a classic poker game where players try to create the best 5-card poker hand. This led to a crash after I played several hands, once the function stack reached its limit. You're using recursive function calls in order to loop (more specifically, you're having the script re-run itself over and over). If you had it output a redstone pulse while dealing cards etc, an attached Note Block could play a 'tick' noise or something.

This is the sort of game that could really benefit from sound. You could cut down on your file count dramatically by embedding all those NFPs into the main script. Do three pikes beat two stars, for example? The rules don't make it clear as to how scoring works.
