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.

Just clean deduction and a board that rewards patience. HOW IT WORKS - Tap once to mark a square you have ruled out - Tap again to place a ghost - Every row, every column and every region holds exactly one - No two ghosts may touch, not even diagonally - Every puzzle has exactly one solution, and you can always reason your way to it A NEW PUZZLE EVERY DAY One fresh board daily, the same for everyone.

Verdict
The clearest difference is in-app purchases: Boodoku at none against Singularity's 7. Singularity's advantage is update cadence (every 2 days vs fortnightly) and ratings volume (8 vs 1). On price, rating, ads and device support there is nothing between them.
