AlgoChess settles staked chess games in ALGO on mainnet ahead of Sept. 20 token mine

AlgoChess is a chess site where you play a normal blitz game against another person or against the Stockfish engine and can stake real ALGO on the result. Both stakes lock into an Algorand smart contract before the first move, and the contract pays the winner straight to their wallet: there is no site balance to cash out and no withdrawal request for anyone to approve.

Two things make it worth reading about this week. The two live contracts are on Algorand MainNet and the escrow does what the site says — the money sits in the contract rather than in an account the operator holds, and settlement pays the player's own wallet. And a token called CHESS opens for mining on 20 September: 20 million¹ coins, no sale, no premine, and no way in except winning a staked game. AlgoChess² is also new, small and unaudited, with no company name attached to it. That part is in here too.

What the board offers, and what each door costs

The app page³ lists five entries: play a human, beat Stockfish, challenge a friend with a link, a friendly game with no stake, and fifty historic mates to solve. Two of them take money.

The clock options are 3, 5 or 10⁷ minutes, the same blitz cadences you would play on a free site. Against the machine, the whole pricing system is one sentence — the further the engine sits above your level, the more a win pays — and it comes as four published steps.

You are always shown two cards: the nearest engine above you at its ladder price, and the one after it, always at ×10⁹. A new player rated 1500¹⁰ sees SF4 at ×2 and SF5 at ×10¹¹. Win, and the contract pays your stake times the multiplier in one block. Beating people never moves those prices — your machine level moves only on games against the machine, and every 300¹² points the menu shifts one engine up. Ratings are Glicko-2, a system in the same family as the Elo numbers most players know, and the site says yours is 'recomputed from the full game history rather than stored as a number we could edit'. That describes how the number is derived, not who controls it: the computation runs on the operator's servers, so it is as editable as any stored value. What it does buy is that the same games always produce the same rating.

A session is quick to start. We opened the practice page¹³ and the board was already waiting, with SF1 to SF8 and 3, 5 or 10¹⁴ minute clocks; clicking SF2 changed the opponent in one click, and the page then flagged our move. The engine runs in the browser, so practice keeps working with the network cut.

A friendly game¹⁵ pairs you with the next person waiting on your clock, or makes a link you can send to anyone: whoever opens it takes black, and they need no account or app. Nothing is stored and nothing is scored, which the page notes is also why a free game cannot be used to move the odds you are offered elsewhere. The fifty legends¹⁶ are mates from Greco in 1619¹⁷ to Carlsen at thirteen, played on a board that answers by itself; progress is kept on your device, which is why ours read 0 of 50¹⁸ solved.

The paid side is where the money is. On the duel page¹⁹ you pick a clock and a stake and create a game that waits for a taker; the machine challenge²⁰ shows the two engine cards with their prices before you commit. Both were honest about how thin the queue is: the lobby read '6 games this week · 2 players · last one 2 days ago' and named its prime time as 9 pm New York.

To stake you need ALGO in a wallet, and the site will make you one in the browser. We did it on the wallet page²¹: it returned an address, a zero ALGO balance and a rating of 1500²², in about ten seconds, with no app and no sign-up. The same page is blunt about what that wallet is — it lives only in that browser, clearing site data deletes it, the 25²³ words are the only copy, and the browser may drop it if the device runs low on storage. The wallet library the site ships carries its own warning in the code: 'Persisting mnemonics to storage is insecure. Any private key mnemonics used should never hold real Algos (i.e., on MainNet). Use with caution!' That tells you how the wallet works — the key is generated and kept on your device, not by the operator — and the site's own copy says the wallet can vanish with the browser. Fund it by sending ALGO from any exchange, and your first staked game opts the wallet in to CHESS automatically, because an Algorand account has to opt in before it can hold an asset.

Why anyone would stake a chess game

Free chess is a solved problem, and the project's own free vs staked page²⁴ says so: 'keep your Lichess account. Keep Chess.com too... Free platforms are the best thing that ever happened to chess.' Lichess²⁵ and Chess.com²⁶ will beat a new site at practice, and AlgoChess tells you to keep them for training and come here when you want the game to count. What it sells is the one thing a free platform cannot: a stake, and a payout that does not depend on someone deciding to honour it. The real-money page²⁷ puts it plainly — 'the blockchain is the bank, not the board'.

The precedent for staked chess is not encouraging, and it is why anti-cheat decides whether this works. Immortal Game²⁸ shut down its NFTs and play-to-earn features in December 2023 over cheating, its team writing that 'by offering large amounts of cash with no limit barrier to entry, we encouraged heavy cheating on the platform and degraded the user experience for our legitimate player base' — a failure reported at the time²⁹ as the end of its ambition to let people earn an income from chess. AlgoChess's answer, per its FAQ³⁰, is server-side analysis of every staked game — move accuracy, engine-agreement rate and move-timing patterns — with sustained engine-grade play freezing an account out of new staked games, stake limits that ramp up for new accounts, and wallets funded from the same source treated as one player. The tradeoff is in the site's own wording: settled money always follows the contract, so a cheater who has already been paid keeps the winnings and loses access instead. The analysis is also run by the operator, on the operator's servers.

Algorand's part in this is narrow and mechanical. Blocks finalise in about three seconds and a transaction costs a fraction of a cent, which is what makes paying out a single chess game practical rather than absurd: the settlement is one transaction in one block, with nothing to batch up. The chain's bigger chess story sits elsewhere — World Chess runs an Algorand-based loyalty programme called The Tower³¹, which tracks progress and rewards rather than staking money on a result.

What the contracts actually say

The live contracts are the ones the site links: EscrowDuel, app 3693252574³²³³, for games between people, and HouseChallenge, app 3693252754³⁴³⁵, for games against the machine. The house contract, the CHESS token and the distribution contract that feeds it were all created on the morning of 3 September. An earlier pair — an older duel contract and an older house contract — sits paused on-chain, so the deployment has already been replaced once since the domain was registered on 18 August 2026. The pages' own code talks only to mainnet hosts, with no testnet endpoint anywhere in it, which matches the site's mainnet label.

The duel contract's own account holds 0.5 ALGO, which is what a pass-through escrow looks like: stakes do not pile up anywhere, and the settlement transactions we read pay players directly out of the contract's account. Some carry a note recording the result, how the game ended — checkmate, timeout — and the whole move list, though not every settlement transaction has one.

The house contract is the funded side. Its account holds 1,427.42 ALGO, about $141 at ALGO's $0.0988 price on 9 September, and 1,424.90 of that arrived on 3 September in a single call from the project's admin address that emptied the older, now-paused house contract into the new one. That is the operator's money backing the machine payouts, not players' stakes, and the outstanding-payout counter reads zero. The ceiling and the odds meet at the top of the ladder: a 200 ALGO machine game won at ×10 implies a 2,000 ALGO payout, which the 285 ALGO ceiling cannot cover, so the largest stake the ×10 price can fully honour is about 28 ALGO, well under the contract's own maximum. Whether the contract refuses a stake that large or simply pays less is not something its published parameters say. The site discloses the ceiling and describes the reserve as what the house can lose.

Both live contracts have one admin address, which is also the treasury and the owner of the algochess.algo³⁹ name — an identity anchored to a verified @algochess account on X — plus a separate oracle address, funded by the deployer, that signs results. That is the trust line worth understanding: the chain enforces the payout rule, but it does not judge the position, so a server the operator runs still decides who won. Beyond the pause flag, the admin's powers are not published, and neither is the contract source — which matters for the constants above, since we cannot tell from the state we can read whether the admin could change a fee or a stake limit. There is no audit that a search turns up, no public repository (a GitHub search for AlgoChess returns unrelated university coursework), no terms or about page and no company name, so the operation is identified mainly by that name-linked wallet. Searching the name also still surfaces an older project at algochess.xyz, described in a 2022 post as an NFT chess game with a pieces marketplace; nothing we found connects it to this site, and the current pages say nothing about NFTs.

The CHESS token and the 20 September opening

CHESS is an Algorand standard asset — the chain's built-in way to issue a token without writing a separate contract — and the one linked from the token page⁴⁰ has a fixed supply of 20,000,000⁴¹ with six decimal places. Its manager, freeze and clawback fields are all set to Algorand's zero address, which disables them: nobody can mint more, freeze a balance or claw coins back. That is a checkable version of the promise that the supply never grows, and it is the kind of guarantee a holder can verify without trusting anyone.

The whole supply sits in the escrow account of the distribution contract, app 3693252995⁴², and that same address is the only account the indexer returned with a nonzero CHESS balance; the two other addresses we saw had opted in and held nothing. The distribution contract publishes six values and no admin or pause key: the asset id, the pool remaining, the epoch, the two game contracts it serves, and an opening timestamp. That timestamp is 20 September at 17:00 UTC, matching the countdown on the site. The pool reserved for the first epoch already reads 10,000,000⁴³ CHESS on-chain — half the supply, which is the site's framing of the first of twenty masters, al-Suli, holding half of everything, with Fischer's epoch last. The rules as published: playing is the only mine, every decisive staked game mines whether it is a duel or a machine game, draws mine nothing, and there is no sale, no airdrop and no team pool. The first epoch mines 1⁴⁴ CHESS per ALGO staked, each later epoch holds half as many coins and mines half as much, and an epoch ends when its pool empties rather than on a calendar. CHESS is not listed on Tinyman or Pact, which matches the claim that it is not sold anywhere. Another contract from the same deployer, app 3693253424, is set up around the CHESS asset with a 5% fee and has never been used — its escrow counter reads zero and its duel counter 1 — so CHESS-staked play has not begun.

You can start without a wallet today: open the practice page and play an engine level, or take a free friendly game against whoever is waiting. When you want the game to count, create the browser wallet, fund it with ALGO and post from 1 ALGO. Check first that staked play is permitted where you live, which the legal page⁴⁵ asks you to do, noting that the machine challenge looks more like a wager against the operator than a duel between two people does. The next thing to watch is the date already written into that distribution contract: on 20 September the mine opens and the first CHESS becomes minable.
