Stack number blocks, make 10 to clear them. A calm math puzzle for short breaks.
Block Math is a number puzzle where the blocks add up. Drag a numbered piece onto the board — onto empty cells or right on top of other numbers — and the values are added together. Hit exactly 10 and the cell clears.
The rule takes a minute to learn. Making every move count takes thinking.
How it plays
- Three pieces wait below the 8×8 board. Drag one into place.
- Where a piece lands on a number, the values add up: a 4 on a 3 makes 7.
- A move is allowed only if no cell goes over 10.
- Any cell that reaches exactly 10 disappears.
- Place all three pieces and a new set arrives.
- The game ends when none of your pieces fits anywhere.
More ways to score
- Three or more equal numbers side by side disappear too. Diagonals don't count.
- Clear several tens at once and each extra ten is worth double the one before.
- Every number right next to a cleared cell grows by 1. If that makes a new 10 or a new group, it clears as well — one move can set off a whole chain reaction.
One endless game, one record to beat
There are no levels and nothing to unlock. Every game starts on a fresh board, and the goal is simple: score more than last time. The home screen keeps your record and shows games played and average score for the last 7 days, the last 30 days and all time.
Play at your own pace
- No timer. Think over every move as long as you like.
- A short interactive tutorial walks you through your first moves, and "How to play" has live demonstrations of every rule.
- Holding a piece over a spot where it doesn't fit? After a few seconds the board outlines a place where it does.
- An unfinished game is saved automatically and waits for you.
- Plays offline.
Lives
Starting a new game costs one life. You have up to 10, and one comes back every hour, even while the app is closed. Continuing a saved game is free.
If you like number puzzles, math puzzles, block puzzles or quiet brain games for a short break, Block Math will feel right at home.
