Tsumiki World

Pack cube-based blocks neatly into a 3D box. Pick, rotate, and fill every gap. The faster you clear, the higher you score. 100 stages, plus leaderboards and achievements.

■ 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.
