No game art, audio, or assets are hosted in this page or its repository. SM63 is a fan-made work by Runouw (whom we are not affiliated with); the game file loads at runtime directly from the developer Runouw's own public repository and is never stored, mirrored, or redistributed anywhere here.

The game above is always free. A pass is only needed to claim a reward or appear on a leaderboard — never to play. This page holds no keys and custodies nothing; every action is signed by your own wallet.
Claim a soulbound Player Pass. Non-transferable by design — it can't be sold, lent or farmed, and it's what gets burned if an account cheats. No prizes at this tier.
Finish the tutorial level in under ten minutes to unlock Cryptographers EXILE — Ch.1, Founders Edition and its password. The run ends at tutorial completion, before the castle.
Qualify by time-locking KAS through a SilverScript covenant — a lock, not a balance check, since borrowed KAS can be snapshotted and returned but committed KAS can only back one entry at a time. Keys never leave your custody, and the covenant's timeout path returns your KAS without anyone else's signature.
Smart-contract distributed prizes, not from entry fees — released by code on result rather than by an operator, and never from anyone's wallet.
Player Pass is an ERC-721 implementing ERC-5192 (minimal soulbound). Administrative roles are held by a multisig, never by this site or any server. Nothing here is a paywall — the game above is free and always will be.
