Block Math: Number Puzzle

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 2 hours, even while the app is closed. Continuing a saved game is free.
