Introducing a new game that teaches players about Yokohama City garbage sorting rules! Play anytime to learn more about the garbage sorting system. ・About This Game As garbage and waste items move across the screen, the player touches and drags them to the appropriate wastebaskets. Putting items in the correct baskets earns the player more points. Although the items scroll slowly at first, they move faster and faster as time passes. Try to sort them quickly and accurately! When a round is over, the player will be awarded a rank based on their score, and items they placed in the wrongs baskets will be shown along with their correct sorting categories. Correctly sort as many items as you can and try to achieve the rank of Sorting Master! Q. What should I do with items when "Waiting for new basket…" is shown? A. When you fill up one of the wastebaskets with items, Io-kun will come and replace it with a new, empty one. You can't add new items until Io-kun has brought out the new basket. Q. Io-kun and Mio-kun sometimes come scrolling across the screen along with the garbage. Should I put them in one of the wastebaskets? A. Io-kun and Mio-kun are super active, and sometimes they even move across the screen with the other items. It wouldn't be very nice to throw them in a wastebasket, so you can just let them go by.

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. PLAY IN YOUR LANGUAGE Fully localized in English, Arabic, Spanish, French, German, Portuguese, Russian and Turkish, with full right-to-left support. No account. No sign-up. No ads mid-puzzle. Just open it and play. Download Gravity Grid: Color Drop and start turning the world.
