Read full description

Foldline is a 60-second "origami × rhythm" puzzle where folding creates music. 【Two simple rules】 ・ Long-press and swipe to FOLD the board, and matching colored tiles disappear when they overlap. ・ Drag with one finger to SHUFFLE tiles into alignment. Fold, clear, fold again. The longer your chain, the denser the beat — and your crash sounds melt into the rhythm. 【How to play】 ・ Use 8-way folds (horizontal, vertical, both diagonals). ・ Tempo accelerates as time runs low. ・ 5+ chains earn time bonuses and fireworks. ・ 10+ chains trigger one of six bonus mini-games: slots, darts, SIMON, and more. ・ A PERFECT clear grants +15 seconds. 【Game Center】 ・ Two leaderboards: Best Score and Total Play Time. ・ Compete with friends worldwide. 【Features】 ・ Fully offline. No ads, no in-app purchases. ・ A complete game every 60 seconds — perfect for any pocket of time. ・ Rich haptics and synthesized sound design. ・ Origami simplicity meets electronic beats. Three gestures — tap, long-press, drag — and a tempo that grows with your skill. Foldline is a brand-new rhythm puzzle where every fold counts.
