Decimo: Number Chain

145 levels across 15 worlds

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

Decimo is a number-chain puzzle that starts with one simple rule and keeps getting deeper: link adjacent cells to build chains of numbers. The longer the chain, the bigger the score. Easy to learn, hard to master. BUILD CHAINS, MAKE THEM POP Drag your finger to connect numbers in ascending, descending, odd, even, or free order. Long chains trigger screen-shaking pops and combo bonuses. 15 WORLDS, 145 LEVELS From exploration forests to ocean depths, volcanoes, a black hole, dreamscapes and beyond time: every world has its own rule and mood. New mechanics are taught step by step, and the Endless Zone awaits when the levels run out. SIGNATURE MECHANICS - Rising Lava: clear downward or get buried. - Creeping Dark: darkness descends from the top, relight it with chains. - Fixed Board: no refill, plan every move. - Boss Fights: hit the exact target sum for double damage. - Ice, stone, bombs, portals, multipliers, and more. 7 POWER-UPS Hint, undo, bomb, shuffle, extra moves, joker, and double score to get you out of a jam. FEATURES - Three independent stars on every level, plus prestige stars - Daily challenges and streak bonuses - Cloud save across devices (optional sign-in) - Dark theme, colorblind mode, haptics and sensitivity settings - Interface in 12 languages Download, build your first chain, and feel the "just one more" pull. Decimo is waiting.

New reminders tell you when your lives are full, when your streak is running or when a new Daily Challenge arrives: at your usual playing hour, at most once a day, never at night. Fairer lives: your first move in a level now uses its life, and winning brings it back, so looking at a level and leaving costs nothing. Your first win on level 1 plays a short scene: the chain you built opens the road to level 2. A rainbow ring now marks the wildcard a long chain leaves behind. Challenge friends in Endless and Time Attack (iOS 26): every run counts, not only your record. The leaderboard has its own trophy on the main menu. Windows now use the game's colours, and the double-reward offer fits in a single window. The board is square on every screen, with its cells centred. Goal descriptions also show the mode and the number to reach, and level 64's first star can now be earned. The Dawn world gets its map scene, and we fixed boss targets no chain could hit, small-screen layouts, a board that could stay stuck and moving up to 7x7 boards. Boss targets are no longer built from hidden cells.
