Skill versus chance
Most gambling law turns on one question: does chance decide the outcome? In chess it does not — there are no dice, no dealt cards, no hidden edge in a shuffle. The better player wins, which is why chess has been played for stakes in cafés and clubs for two centuries, and why many jurisdictions treat skill-based head-to-head wagers differently from games of chance. A staked duel on AlgoChess is exactly that shape: two players, equal stakes, and a result decided entirely by the moves.
The Stockfish challenge is a different shape, and we say so: you play against an engine at fixed, published odds, with a margin built into the multiplier. That looks more like a wager against the operator, and some jurisdictions treat it accordingly.
What that means for you
Rules differ by country and sometimes by region, and we are not your lawyer. Staked play must be permitted where you live, and you must be of legal age. If either is not the case, the free practice — every engine level, offline, unlimited — is yours regardless.
What we do on our side
Total transparency. The escrow and payout rules are smart contracts on Algorand MainNet, public and inspectable. The fee is 10% of a duel pot, 1% on a draw, stated on every page from the same constants the contracts settle with. Every payout is a public transaction.
No custody. We never hold player funds. There is no site balance to freeze, no withdrawal to approve, no bankroll of yours in our hands. That does not settle every legal question, but it removes the biggest practical risk of money-games online: the operator who simply keeps the money.
Fair play enforced. Server-side engine analysis on every staked game, stake limits that ramp with history, and freezes for engine-grade play — because a staked game is only worth playing if the opponent is human.
Skill first, always. Stake only what you can afford to lose. Chess for stakes should feel like a sharp Friday game among equals — if it ever feels like more than that, step back to the free board.
