Guide falling numbers into buckets that divide them evenly. Build combos, unlock 15 Game Center achievements, and climb the leaderboard.
Modulo Squares turns divisibility into a fast, strategic arcade puzzle.
A number falls. Ten buckets wait. Guide the tile left or right, then drop it onto a bucket that divides it evenly. A clean match grows your score and combo. A remainder costs points. The red Dead bucket costs the falling number, so every decision matters as the numbers grow and the timer speeds up.
HOW TO PLAY
• Move the falling number left or right across ten lanes
• Choose a bucket that divides the number evenly
• Drop early when you know the answer
• Build combos to increase your movement speed
• Fill the 10 × 10 progress grid to reach the next level
• Adapt as the number range expands and the fall timer accelerates
FEATURES
• Quick, replayable number-puzzle runs
• Optional visual cues that highlight valid buckets
• Four color themes to choose from in Settings
• A persistent local best score to chase
• Clear scoring, combo, speed, range, and progress feedback
• Play free with short ads between levels
• Optional one-time Unlock Premium purchase to remove ads
• Optional Game Center leaderboard and 15 achievements
• No account needed; your best score stays on your device
Modulo Squares is made for puzzle fans, number-game players, and anyone who wants arithmetic practice to feel like an arcade challenge instead of a worksheet.
How long can you keep the numbers falling?
