About PokerGrid 4x4
PokerGrid 4x4 adds a strong bot to the 4x4 poker card game Pile-Up Poker on Puzzmo.
COMPETE MODE (default)
Play the game on your own, with no help. When you finish, the bot plays your exact four hands and you get a replay of both games side by side:
• both boards fill in round by round, with every scoring hand labeled
• the final score breakdown for you and for the bot
• a round-by-round check of your game: how many expected points each of your rounds cost, and what the bot would have played from your position
SUGGEST MODE
See the bot's best move while you play, with its plan for the rest of the round and the card to discard.
HOW THE BOT WORKS
The bot is a search over whole rounds guided by a neural network trained with reinforcement learning. It never looks at face-down cards: future hands are sampled only from cards you cannot see. It runs entirely in your browser (JavaScript and WebAssembly). No server, no account.
