Market Maker is a card game about market-making. 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. Each player holds a private card. A set of community cards is revealed round by round. The true value of the hand is the sum of all cards — but nobody knows it yet. Your edge is how precisely you can estimate it, and how well you read your opponents. HOW IT WORKS You post a bid and an ask spread. Your opponents can buy from you or sell to you. The tighter your spread, the more trades you attract — but the greater your exposure if your estimate is wrong. At settlement, cards are revealed and profits are calculated exactly as on a real trading floor. TWO TRADING MODES Turn-Based: Quote, react, and adapt at your own pace. Study the market before committing. Live Order Book: A 40-second live trading window with real-time AI re-quoting. Update your spread dynamically as new information arrives. The pressure is on. YOUR OPPONENTS Rookie — noisy estimates, wide spreads, impulsive reactions Shark — bluffs confidence, posts misleading quotes to trap you Pro — tight spreads, reads your quotes to infer your private card, executes arbitrage CAREER MODE Work your way through a four-stage trading tournament. Start at a university trading floor against rookies. Survive the sharps to reach MegaBank's live trading desk. Beat the firm's best algorithms and secure the internship. ACHIEVEMENTS & GAME CENTER 17 achievements from First Flip (common) to Winner (legendary). Five leaderboards — all-time profits and per-stage career performance — ranked globally on Game Center. ANALYTICS Every hand ends with a full performance breakdown: P&L timeline, trade-by-trade edge quality, player comparison, and an Analyst Rating from S to D. PRICE Free to download. Upgrade to Pro to unlock Live Trading mode, career stages 3 and 4, and the Pro AI opponent — one purchase, no subscription.

Verdict
The clearest difference is ads: Market Maker at none against Founder Sim's shown. Founder Sim's advantage is update cadence (every 3 days vs every 6 weeks) and ratings volume (36 vs 1). On price, in-app purchases, device support and iOS requirement there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Founder Sim sells 10 one-off in-app purchases and Market Maker sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
Founder Sim holds the better App Store score, 4.3 against 4.0. That said, the two scores are not equally well evidenced: Founder Sim has 36 ratings behind it against 1, so its average is the more settled of the two.
Founder Sim ships an update every 3 days, Market Maker every 6 weeks. Both last shipped on November 5, 2026.
