Fillomino – Number Blocks

About this app

Place a number, and equal numbers join into a block. That number is the size of its block—nothing more to memorize. Just three simple rules. Fillomino is a pure logic puzzle where you fill every cell of the grid with a number. No arithmetic, no guessing—only careful observation and clean deduction. From a gentle 5×5 to a demanding 11×11, it fits a spare minute on the train or a slow evening at home. The three rules - Fill every cell with a number. - Cells of the same number, joined across or down, form a block exactly that many cells in size. - Two blocks of the same size may not touch across or down (diagonal is fine). Features - Four difficulties: Easy (5×5), Medium (7×7), Hard (9×9), Expert (11×11) - A new Daily Fillomino every day—everyone in the world gets the same puzzle - Records: daily streak, best times, no-hint rate, and a solved calendar - Blocks are colour-coded so the solution reads at a glance - Pencil marks with auto-cleanup, plus a gentle mistake indicator - A hint when you're truly stuck - Dark mode, with a calm, paper-and-ink Japanese palette - English and Japanese Made for you if… - You've solved every Sudoku and want the next number puzzle - You want a clear head on your commute or before bed - You're tired of ad-heavy, paywall-pushy puzzle apps - You love a puzzle that's simple to learn and deep to master - You enjoy watching your records grow, one day at a time Play with peace of mind - No account or sign-up required - Your records stay on your device only—nothing is sent to any server - Works fully offline (the daily puzzle is generated without a connection)
