Seven Puzzle
A calm 3D cube puzzle
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Seven pieces.
Turn them, place them, and somewhere along the way — a perfect cube.
Seven Puzzle began as a hands-on teaching tool, used in real gifted-education classrooms in Korea. Korea Education Contents Lab founded Uncut Stone Studio to rebuild the puzzle children learned with their hands — as a game you can carry.
There's no rush. No hearts, no energy bar, no lives to run out. One quiet round before sleep — a little motivation, a small win to end your day.
■ Two challenges, 700 stages
• Minimap Challenge, 200 stages — follow the small cube picture, starting with one piece and gradually working up to seven
• Coordinate Challenge, 500 stages — read the layer-and-column table and fit all seven pieces
• Collect stars to open new sections of the Coordinate Challenge
• Short rounds that fit into real life — before sleep, on the train, in a spare minute
■ World Championship
• Compete with the world in two disciplines, Minimap and Coordinate
• One puzzle a day in each discipline, and seven days to a season
• Each day, the three best solvers in each discipline take gold, silver and bronze
• World rankings and medal tallies by country
■ Curious about your spatial reasoning?
• Spatial Intelligence Report — compare your results with players worldwide whenever you like (optional)
• Stamps — twenty-two, collected quietly in your stamp book as you play
■ Anywhere
• Dark mode and calm themes that are easy on your eyes at night
• The puzzles play offline — on a plane, underground, wherever
• Available in 13 languages
• One premium purchase (not a subscription) plays ad-free, with hints and exclusive skins
At the end of the day, one quiet puzzle is enough.
