Tsumiki World

■ Fill the box. No gaps. Tsumiki World is a 3D fitting puzzle where you pack cube-based blocks neatly into a box. The rules are simple: pick a block, line up its orientation, and place it inside the box. Fill every gap and the stage is cleared. ■ Think fast, fill faster Every stage has a time limit, and a faster clear means a higher score. Your remaining time becomes your score, so even solved stages are worth replaying to beat your best. ■ Intuitive 3D controls - Pick a block from the tray - Set its position with the arrows and its orientation with the rotate button - Tap inside the box to place it, tap again to confirm - Long-press a placed block to undo it Drag to rotate the box and inspect it from any angle. One tap snaps the view back to the start. ■ 100 stages From a gentle 2×2×2 warm-up to brain-bending packing puzzles, difficulty ramps up across 100 stages. Clear one to unlock the next. ■ Leaderboards & achievements (Game Center) Compete on the total-score leaderboard and collect 16 achievements — clear-count milestones from First Clear to All Stages Cleared, skill badges like High Score, Perfect, and Speed Star, the No-Undo streak "Flawless Builder", and gallery goals like Collector and Gallery Complete. ■ Character collection Characters you meet across the stages are added to your gallery. Rarity runs N → N+ → R → R+ → SR — the rarer the block, the more it sparkles. ■ Great if you - Want a quick brain teaser for spare moments - Prefer thinking puzzles over fast falling-block games - Enjoy Soma cube and block puzzles - Love the satisfaction of a perfectly packed box Fit every piece.
