BTC Puzzle Game – an incremental browser game that does a real search on the puzzles

Hi all,

I made a small incremental game around the 2015 puzzle transaction, built on the list here on btcpuzzle.info:

How it works

• Every die you roll is a real private key in the selected puzzle’s range. The game derives the hash160 and compares it with the puzzle address.

• Rewards come from how many leading bits of the hash match. Credits buy more dice, auto-rolls, CPU workers (WASM + SIMD) and a WebGPU search.

• You start on a ladder of already-solved puzzles (#5 to #40), where you really find the (public) keys. Unsolved #71 and up are always open.

• A global leaderboard ranks the best partial matches (most matched bits, then the higher puzzle number).

Expectations
It’s a game, not a serious solver. A browser at 10–200M keys/s will never realistically find #71, and partial hash matches don’t bring you closer to the key. Dedicated tools are far faster. The search is still real, and it’s random, so in theory anyone could get lucky.

Privacy
Everything runs in your browser. Nothing is sent unless you submit a record to the leaderboard, which requires a Google sign-in. Submitting sends your nickname and the partial-match key. A key that fully matches an unsolved puzzle is never sent.

Feedback is welcome, especially on GPU speeds on your hardware (there’s a built-in benchmark) and on balance. Thanks to btcpuzzle.info for the puzzle data!
