Erwin - A Quantum Puzzle
Relaxing Match & Merge Game
Only for iPhone
$4.99 · Designed for iPhone. Not verified for macOS.

A quantum twist on the classic sliding puzzle — in 3D, on a cube.
Erwin is a sliding puzzle played on the six faces of a 3D cube, each a 4×4 grid.
Swipe to slide and merge tiles, or swipe the background to rotate the cube and work the other sides.
Tiles have value, doubled as they merge. Each merge adds to your score.
Play long enough and quantum effects begin to appear: some tiles are in superposition, alternating between two values, and either one can merge.
Erwin respects your privacy and your wallet. This is an app I wanted for myself without compromise or dark patterns: it has no ads, no nagging in-app purchases, no tracking, no profiling.
