Bitcoin Puzzle Quest

Features
Read full 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 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 (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, how many puzzles you've attempted, and see how you stack up against friends and puzzle hunters worldwide. Attempt counts are reported in million-key milestones, and no key value ever leaves your device. Key Features • Human-Friendly Cryptography Experience. Just tap, scan, and get feedback. We’ve made cryptographic puzzle solving fun, simple and accessible. • Offline & Private. All key generation and address checking happens locally on your device. No internet, no tracking, no wallet integration, no cloud needed. Just pure, private puzzle solving. • Random or Sequential Runs. Switch between secure randomness or reproducible scans. • Live Puzzle Balances. View the live balance of each puzzle address for extra motivation. Stay informed, stay inspired. • Haptic Alerts for Instant Celebration. When you hit the correct number (fingers crossed!), you’ll feel a satisfying haptic buzz and see the winning key. • Adaptive UI. Supports Light and Dark Mode, Dynamic Type, and is fully iOS-Universal. Privacy-First Philosophy • Found numbers are stored locally, never shared and no third parties involved. • Attempt counts, number of tries, are saved to your device (unless you join Game Center). • Network calls are limited to public endpoints for puzzle address balances and the ticker. Who’s It For? Anyone curious about cryptographic puzzles especially about Bitcoin. Whether you’re an experienced puzzle hunter or totally new to blockchain, Bitcoin Puzzle Quest offers a playful, intuitive way into a legendary number searching puzzle.  Ready to hunt the biggest cryptographic puzzle?  Download Bitcoin Puzzle Quest and start your adventure today!
