Bitcoin Puzzle Quest

Choose your key size and hit 'Go'.
Test the keys to unlock big bounties of the legendary 1000 BTC Puzzle.

App Description

Become a famous puzzle hunter and test your luck against one of the most famous cryptographic challenges on the internet. Somewhere in blockchain's vast key-space lie dozens of addresses tied to a publicly known cryptographic puzzle setup more than a decade ago. Every one of the addresses is protected by nothing more than an unknown number within a known range. Bitcoin Puzzle Quest puts this legendary hunt in the palm of your hand.

How to Play

1. Choose Your Challenge

Pick any key size up to the 160-bit “beast”. The larger the space, the harder the challenge.
Not sure where to begin? Try 71-bit in Speed Dial: the lowest-bit puzzle still unsolved, with an untouched real prize, and a bit count still humanly conquerable.

• Low-bit puzzles (already solved) offer quick feedback and are great for experimentation and learning.
• High-bit challenges bring the thrill of chasing life-changing bounties.

2. Generate and Check Keys Instantly

• Tap to Hunt. Generate keys one-by-one or in batches of 5, 10, 50 or 100.
Each key is converted locally to a Bitcoin address, and checked against the official puzzle address list—all offline. Keep tapping until you find the correct number (or your thumbs tap out… pro tip: a DIY “robot finger” is totally fair game).
• Continuous Mode (one-time in-app purchase). Let the app press the button for you. No tapping required. Perfect for committed puzzle hunters who’d rather watch the numbers roll than their fingers ache. You can even enter a starting number for deterministic, sequential scans - ideal for targeting specific ranges or coordinating community efforts with fellow puzzle enthusiasts.
Need a breather? Double-tap the treasure-chest icon to reveal a cheeky sliding-puzzle mini-game. Because every great quest deserves a hidden side quest!

3. Global Leaderboards (Game Center)

Compare how many millions of keys you’ve tested, and see how you stack up against friends and puzzle hunters worldwide. Counts are reported in million-key milestones, and no key data ever leaves your device.
