27 sudoku grids interlocked in a single cube. Everything is free, with no ads and no subscription. A classic sudoku fits on one grid. SudoKUB stacks twenty-seven. A KUB is a 9 × 9 × 9 cube of cells. Every one of its planes — nine in each direction — is a complete, valid sudoku grid. Placing a digit constrains it in all three at once, and exactly one solution exists. EVERYTHING IS FREE All three modes, all five formats, every aid, both themes, VoiceOver and large text sizes. Nothing is locked behind a payment. Only the pace of new KUBs changes. GRASP THE SPACE IN MINUTES Three exercises take you there step by step: one grid, then a crossing, then all three families of planes. Five to eighteen minutes each, and the space is yours. FOUR LEVELS, FOUR WAYS OF THINKING From Easy to Expert, what changes is not how many clues you get but how deep the reasoning runs. And no level ever asks you to guess: every KUB is finished by pure deduction. AIDS THAT SHOW, NOT SOLVE Digit focus, cascade signalling and constraint rays let you see what you could have found yourself. All of them can be turned off. THE KUB OF THE DAY Every morning, a short timed KUB, the same one for everyone. Beat the target time and earn a key. NO ADS, NO SUBSCRIPTION, NO DATA COLLECTION No advertising. No subscription. Nothing leaves your phone apart from Game Center and the App Store. A single purchase unlocks unlimited KUBs: once, forever.
