A new GitHub project called SatoshiGuesser transforms Bitcoin cryptography into a slot machine game, attempting to randomly generate Satoshi Nakamoto's private keys. The web application rolls random 256-bit numbers to derive Bitcoin addresses, checking against a curated set of 21,954 Patoshi-pattern addresses plus the genesis block. Each spin carries odds of roughly 1 in 5.27 × 10⁷², making winning astronomically improbable.

The implementation relies entirely on client-side cryptography with no server or API dependencies. A Bloom filter (~135 KB) enables fast address lookup, while a sorted table (~615 KB) provides balance information. The game supports both classic 3-reel and realistic 64-hex-cell modes, achieving approximately 2,500 spins per second with no-delay mode enabled.

Built with Node 22+ and Web Audio API for synthesized sound effects, the project includes 11 unit tests covering cryptographic operations and end-to-end scenarios. The wallet dataset represents 1,097,702.49 BTC across all tracked addresses. While mathematically sound, the practical value remains essentially zero—winning would require generating the exact private key controlling wallets worth hundreds of millions of dollars.

The project serves more as a cryptographic demonstration than a serious tool. It showcases Bitcoin's address derivation chain: private key → secp256k1 public key → HASH160 → Base58Check address. Developers can run spins locally or deploy to Cloudflare Pages as a static site.
