You read
the book.
Now play
the game.
Inspired by the card-based trading competition described in The Trading Game. Bid, ask, bluff and outsmart the table — just like Gary Stevenson did to win his internship.
A market in your hand. Three moves to master it.
Everyone holds a hidden card. The community cards fill in the truth. Your job: quote a price others will trade against — and be right more often than the bots.
Read the table
You see your own card and shared community cards. Estimate fair value while everyone else does the same — on incomplete information.
Quote a market
Set your bid and ask with the spread slider. Tight markets win flow but carry risk. Wide markets stay safe but miss the action.
Hit, lift, or pass
Trade against the bots' quotes when you spot an edge. Build a position, manage your risk, and settle up when the cards are revealed.
Real-time
or turn-by-turn.
Play the fast lane — a live order book ticking down on a clock, bots firing quotes in real time. Or slow it right down to a turn-based duel where every decision is deliberate.
Trade on what others can't see
Your card is yours alone. The edge goes to whoever reads the table best.
Four rivals, four playstyles
Naive, Bluffer, Analyst and more. Each bot reasons, quotes and bluffs differently.
