Everything about $STACK

How the game works, how prizes are paid, and the rules and terms that apply when you play.

About

STACK is a free-to-play browser game based on the classic block-stacking format. Drop each slab on top of the last one; whatever hangs over the edge gets cut off. Line it up perfectly to keep your full size. Miss completely and the run ends.

The game runs in rounds. Whoever has the highest score when the round timer reaches 0:00 wins that round's prize pot, paid in SOL on the Solana blockchain. The pot is funded by creator fees from trading of the $STACK token on pump.fun.

Playing is free. You don't need to buy or hold anything to play or to win. Connect a Solana wallet to save your scores and be eligible for the pot. You can also play without one as a ghost, just for fun.

Game rules
  1. Entry. Connect a Solana wallet and choose a player name. Your name is linked to your wallet. Without a wallet you can play as a "ghost": ghost runs aren't saved, don't appear on the leaderboard and can't win. Names must be 3–16 characters (letters, numbers and _). Names that are offensive, misleading, impersonate the team, or look like someone else's name are not allowed.
  2. Rounds. Each round lasts 10 minutes. A new round starts automatically when the previous one ends.
  3. Attempts. You may play as many runs as you like during a round. Only your best score in that round counts.
  4. Scoring. Your score is the number of blocks you place before the run ends. Scores are calculated by the game server, not by your browser.
  5. Timing. A run counts toward the round in which it finishes. Runs that finish after the timer reaches 0:00 count toward the next round.
  6. Winning. The highest score at 0:00 wins. If two players have the same score, the one who reached it first wins.
  7. Minimum players. A round needs at least 3 players with a saved score for a prize to be awarded. Ghosts don't count. Otherwise the pot carries over to the next round.
  8. Pauses. We may pause rounds (for example for maintenance). Scores set while rounds are paused don't count.
Prizes & payouts
  1. Prize amount. The winner receives the full prize pot as shown at the moment the round ends. The amount is locked at that moment and shown on the win screen.
  2. Where it goes. The prize is sent to the wallet you had connected when the round ended. Check you've connected the wallet you want paid.
  3. Payment. When a round ends, the prize is sent automatically from the game wallet to the winner's connected wallet, usually within a minute. The next round starts once the winner has been paid. You don't need to do anything or contact anyone. Every payment is shown publicly under "Past winners" with its transaction.
  4. Fair play. Wins that break the fair-play rules can be cancelled, and the prize goes back into the pot.
  5. Final. Blockchain transfers can't be reversed once sent.
  6. Network fees. We cover the Solana network fee for sending your prize.
  7. Taxes. You are responsible for any taxes that apply to prizes you receive in your country.
Fair play

The game is meant to be won by skill. The following are not allowed:

  • Bots, scripts, macros, auto-clickers or any automated play.
  • Modifying the game, tampering with network traffic, or exploiting bugs.
  • Using multiple names to manipulate a round, or colluding with other players.
  • Impersonating other players or the team.

We may remove names, void scores, withhold or cancel prizes, and block players we reasonably believe have broken these rules. A cancelled prize goes back into the pot. Our decision on fair-play issues is final.

If you find a bug, please report it to us instead of using it.

  • Cryptocurrency prices are extremely volatile. You can lose all of the money you put in. Only use money you can afford to lose.
  • We make no promises about the token's price, liquidity, listings or future development.
  • Buying the token is not required to play or win the game, and holding it does not improve your chances.
  • Market data shown on this site comes from third parties and may be delayed or inaccurate.
  • Never trust anyone who DMs you claiming to be from the team, offering prizes, or asking for your seed phrase or for you to send SOL.
Terms of use

By using this website you agree to these terms. If you don't agree, please don't use the site.

  1. Eligibility. You must be at least 18 years old (or the age of majority where you live) to win prizes. Prizes are void where prohibited. It's your responsibility to make sure taking part is legal where you live.
  2. As is. The game and website are provided "as is", without warranties of any kind. We don't guarantee the site will always be available, error-free or uninterrupted.
  3. Changes. We may change the rules, round length, prize settings or these terms at any time. Changes apply from when they're posted here and don't affect prizes already won.
  4. Errors. If a technical error affects a round (for example a server fault or wrong prize amount), we may void or re-run that round, or correct the result.
  5. Liability. To the extent allowed by law, we are not liable for any loss arising from use of the site, the game, the token, third-party services, or blockchain transactions.

Privacy

We collect as little as possible.

  • What we store: your player name, your scores, and the public address of your wallet if you connect one.
  • Public: your player name, scores and wins are shown on the site. Payout transactions are public on the Solana blockchain by nature.
  • Your browser: we keep a random player key in your browser's local storage so the site remembers your name and linked wallet. Clearing your browser data removes it.
  • Wallet connection: connecting only shares your public address. We never request transactions or signatures that move funds, and we can never access your funds. You can disconnect at any time.
  • What we don't do: no accounts, no emails, no selling of data, no ad trackers.
  • Third parties: market data is loaded from public services (such as DexScreener and CoinGecko), which may see your IP address when your browser requests it.
Contact

Questions, bug reports or prize issues: message us on X. We'll never DM you first, and we'll never ask for your seed phrase or for you to send funds.
