Gravity Grid vs Cubdoku

Turn the world. Watch everything fall into place. Gravity Grid is a puzzle game with one beautifully simple rule: you never touch the blocks. You rotate the entire board — and gravity does the rest. Every block tumbles, slides and stacks in the direction you chose. Land each colour in its matching exit and the level is solved. Easy to understand in three seconds. Surprisingly hard to master. WHY YOU'LL KEEP PLAYING • One rule, endless depth — a single rotation moves every piece at once, so every turn matters • 9,540 levels, hand-tuned in difficulty from your very first board to genuinely brutal • Never unwinnable — every level is verified solvable, and no wrong move can dead-end you. If you're stuck, it's a puzzle, not a bug • No timers on most levels — think as long as you like • Fully offline — every level is on your device. Play on a plane, on the subway, anywhere MECHANICS THAT KEEP IT FRESH New ideas arrive gradually, each one taught on the level it first appears: • One-way gates that only let blocks through from one direction • Portals that teleport blocks mid-fall • Glue tiles that anchor a sliding block in place • Colour-swap tiles that change a block as it passes • Locked exits that open only once you've cleared a colour • Linked blocks that move as one • Jokers that fit any exit • Move limits, when the puzzle needs the pressure POWER-UPS FOR WHEN YOU'RE STUCK • Hint — shows you the next right move • Hammer — send any block straight to its exit • Undo — take back a rotation • Rocket — plays the best move for you • Freeze — buys you extra moves or extra time RELAX, OR COMPETE WITH YOURSELF Earn up to three stars per level. Chase a perfect run. Take on the Daily Challenge for bonus rewards. Or just play a few boards before bed — it's that kind of game.

Cubdoku is a cozy logic puzzle built around one simple rule set and an adorable bear cub mascot. HOW TO PLAY Place exactly one cub in every row, every column, and every colored region — and make sure no two cubs ever touch, not even diagonally. Mark cells you've ruled out with an X, use auto-marking to skip the busywork, and let the puzzle click into place. Easy to learn in under a minute. Genuinely hard to master as the boards grow from 5x5 up to 10x10 and the difficulty climbs from Easy to Expert. A NEW PUZZLE EVERY DAY Solve a fresh daily puzzle, build a streak, and watch your calendar fill in. Miss a day and your streak resets — so does tomorrow's puzzle wait for you either way. Your streak, stats, and puzzle history are all saved right on your device. 784+ HAND-VERIFIED PUZZLES Every puzzle in Cubdoku is generated and verified to have exactly one solution before it ships — no guessing, no ambiguity, just clean logic.
