SudoKing reinvents Sudoku with 2 superimposed grids: the first with 9 numbers, the second with 9 colors. Each number from 1 to 9 and each color must appear only once in every row, column, and 3 × 3 box. But 1 additional rule changes everything: each of the 81 number-color combinations must also be unique. A simple rule that opens up new deductions and completely transforms the Sudoku experience. Progress through 7 levels, watch your avatar evolve, solve historical riddles, and hunt for the Easter egg hidden in every grid. The Beginner level is free and unlimited. Other levels and options are available as in-app purchases, with no subscription. 9 numbers × 9 colors = 81 unique combinations. You’ve never played Sudoku like this.

A color-matching puzzle with a twist: the whole board turns. In Singularity: Gravity Match, drag to guide falling pieces toward matching colors as a black hole pulls them inward. Clear space before the edge fills up, and look for the match that keeps your run going. Build lines, triangles, and rings instead of swapping pieces on a fixed board. Special powers give you more ways to handle a crowded board: clear a line, remove a color, or slow the action. Choosing when to use them is part of the puzzle. Explore 200 levels across two seasons and 20 space destinations, with wormhole crossings along the way. Finish Season 1 to unlock Season 2 and Arcade, where a faster pace puts your matching skills to the test. Try Orbit Rush for a different challenge. Keep clearing tiles as 20 space destinations pass by, and see how high you can push your score. Chase your personal best, complete daily missions, and compare scores on Game Center. Turn the board and see where your next match takes you.
