In 2015, someone created a series of Bitcoin wallets with increasingly large bounties. The private keys to these wallets can be found by searching through a specific range of numbers.
The earlier puzzles have been solved. The remaining puzzles hold millions in BTC — and finding the right key is like winning a lottery where you control how many tickets you buy.
Our edge: While most pools focus on one puzzle at a time, we randomly search across 3 puzzles simultaneously — tripling your chances of being part of a winning pool.
Most pools bet everything on one puzzle. We don't.
If another group solves Puzzle #71 tomorrow, single-puzzle pools lose everything. We don't. We've already searched a massive chunk of #72 and #73. That progress stays with us.
When a puzzle gets solved — by us or anyone else — we simply add #74, #75, and beyond to our rotation. Zero downtime. Zero lost momentum. The search continues seamlessly.
Every key we check across all three puzzles is progress that never disappears. Your contribution today still counts even if the puzzle landscape changes tomorrow.
Grab our mining client for Windows or Linux. Requires an NVIDIA GPU (GTX 1060 or better recommended).
Enter your Bitcoin address, connect to the pool, and start searching. Your contribution is tracked in real-time on the website.
If the pool solves a puzzle, payouts are automatic. Your share is based on your contribution percentage shown in the stats.
No hidden fees. No upfront costs. You only share if we win.
The Bitcoin Puzzle Challenge was intentionally created as a public cryptographic challenge. The creator deliberately funded these wallets and published the address ranges as an open invitation for anyone to solve them.
This is no different than:
We are not attempting to crack random wallets or access anyone's funds without permission. The puzzle wallets were specifically created to be solved. The creator wants someone to find the keys — that's the entire point.
The Bitcoin Puzzle transaction is permanently recorded on the blockchain (transaction from 2015). The challenge rules and key ranges have been publicly documented for years. This is a transparent, opt-in competition.
GTX 1060 or better recommended. The client uses CUDA for GPU-accelerated key searching.
Native clients available for both operating systems. Same performance, same features.
Consistent connection to receive work assignments and submit results to the pool.
Your BTC address for receiving payouts. That's it — no account creation needed.
Low for any individual key, but non-zero. Unlike traditional lotteries, your contributions accumulate. Every key checked is progress. And searching 3 puzzles means 3x the opportunities.
Random searching means every key has equal probability of being the winner, regardless of when you join. No advantage to early participants — the odds are always fair.
Your contribution percentage is tracked in real-time on btcmultipuzzle.com. It's based on the verified work your GPU submits to the pool relative to everyone else.
If your machine is the one that discovers the winning key, you get an extra 10% on top of your normal contribution share. A reward for being the lucky one.
Our client is optimized for CUDA, which provides the best performance for this type of computation. AMD support may come in the future.
No signup. No fees. Just download the client, point it at your Bitcoin address, and start contributing.
