Number Puzzle: Math Tiles

Place number tiles so a row or column adds up to the target, and that line clears. A quiet number puzzle.

That one line is the whole rule. But where you place a tile changes what comes next, and a single move can clear a row and a column at once. This is not a race to do arithmetic fast — it is a logic puzzle about designing space with numbers.

■ Who it's for

· Anyone looking for a quiet brain game and daily brain training
· Fans of number games, logic puzzles, and brain teasers
· The commute, the coffee break, the half hour before sleep
· Anyone who wants to think without a timer counting down

■ Two modes

· 40 stages — from 3x3 to 5x5. A solver checked that every board can be finished
· Endless mode — boards keep coming. How far can you get?
· Leaderboard — compare your endless score with other players

■ Four kinds of block

· Number block — adds to the line's sum
· Operator block — applies + or − to the whole line's sum. It stays put even after the line clears
· Ice block — the first clear only cracks it. Clear its line twice to break it
· Bomb block — clear its line before the fuse runs out, or the board ends
■ Made to be easy on you

· Auto-save — close it mid-board, open it, carry on
