This is not just any puzzle game. This is a quantum puzzle game! You can just play it for fun, or you can use it to conduct scientific research in the field of quantum error correction. These are the puzzles that need to be solved to keep quantum computers free of errors. We need to work out the best way to do it. By becoming a master at this game, you could help build a real-life quantum computer. Check out our website for more details on the science behind the game. This app was developed by Dr James Wootton, a quantum error correction researcher at the University of Basel. It is supported by the NCCR QSIT.
Moonkeeper

Drag the Moon. The sea follows. Moonkeeper is a physics puzzle game about gravity and the tides. A tiny ocean planet spins in space, and its water always bulges toward the Moon. Move the Moon with one finger and you move the sea: lift boats over sharp reefs, pull the water away so pirate ships run aground, send a wave over a burning forest, and float stranded whales back into deep water. Every level is a compact puzzle with its own goal and its own clock. Plan your sweep, time the tide, and keep the villages dry, because too much water washes houses away. HOW TO PLAY • Drag anywhere to move the Moon around the planet • The sea rises under the Moon and falls on the other side • Complete the level's goal before time runs out: dock the boats, wreck the pirates, save the whales • Beat the clock for 3 stars 5 WORLDS, 100+ LEVELS • Azure Cradle: guide boats home and keep the villages dry • Ember Isles: volcanic islands where dry forests catch fire • Frostmere: icy shores where whales get stranded • Verdant Reach: rice fields that need a gentle tide • Twin Moons: a second moon pulls the sea on its own Every level has been played through and proven winnable, so a solution is always there to find. FEATURES • One-finger controls, easy to learn and hard to master • Real tide physics: the water flows toward the Moon • 300 stars to earn and a best time to beat on every level • Power-ups when you need them: Slow down time, Freeze pirates, fires and whales in place, or get a Hint • Earn stardust and collect magical moons: Blood Moon, Neon Moon, Eclipse and more • A daily stardust gift that grows with your streak • Charming worlds, calm music and satisfying water Pick up the Moon and start moving the tides.

Verdict
The clearest difference is ads: Decodoku at none against Moonkeeper's shown. Decodoku also leads on iOS requirement (8.0 vs 15.0). On price, in-app purchases and device support there is nothing between them.
