Foldku - Fold to 1

Foldku is a quiet folding puzzle. Every card has two colored faces. Fold a card onto its neighbor when their top colors match. The card flips and stacks. Keep folding until a single card remains. Simple to learn, deep enough to sit with. ALL 300 LEVELS, FREE Nothing is locked behind a paywall. The first 40 levels are completely ad-free; after that a short ad appears every few puzzles. One tap in Settings removes them forever if you'd rather play uninterrupted. NO TIMERS, NO LIVES Nothing hurries you and nothing runs out. Your progress stays on your device (and in your own iCloud, if you want it on every device). 300 HANDCRAFTED LEVELS Twenty chapters, each with its own quiet mood. Every level is generated and then verified by a solver, so a solution always exists. Difficulty is measured by how easy it is to go wrong, not by how many tiles are on screen. A NEW PUZZLE EVERY DAY Everyone gets the same daily board. Solve it, keep your streak, and come back tomorrow. Miss a day? A weekly streak freeze has your back. ENDLESS ZEN MODE No stars, no timer, no pressure. The difficulty quietly adapts to how you're playing. Fold for one minute or twenty. MADE TO FEEL GOOD Paper-soft sounds, gentle haptics, a fold that curls from the corner you touch. A dark theme for late nights. Everything can be turned off if you'd rather play in silence. SEVEN LANGUAGES English, Español, 中文, 한국어, 日本語, Français, Türkçe. Switch any time inside the app. Foldku is for the ten minutes when you want your brain busy and your shoulders down.
