About
Two magnets. One elegant puzzle.
DUOLOCK charges the classic sliding-block puzzle with magnetism. Every magnet is linked to a partner: move one and the other answers — pulling closer or pushing away. Clear a path, line up the pair, and slide each block home to its lock.
It starts simple. Then ice tiles appear — slippery ground a block can't rest on. Then rocks — fixed walls you must route around. Piece by piece, DUOLOCK teaches you a language of motion, then asks you to speak it fluently.
• 2,030 hand-crafted levels — never randomly generated. Five bands, from gentle tutorials to expert puzzles that will genuinely stump you.
• A fresh Daily Challenge every day — build a streak and guard it with a Streak Freeze.
• Endless mode — a continuous run at the difficulty you choose.
• Scores and personal bests — solve faster, in fewer moves, without hints, and chase a new record.
• Achievements to unlock as you master each mechanic.
• Hints for when you're truly stuck, earned by playing.
DUOLOCK is calm, clever and completely offline. No ads. No accounts. No tracking. Every level lives on your device, so you can play on a plane, underground, or anywhere your mind needs a quiet challenge.
Turkish and English included.
