Each blank sits on an across line, a down line, or both. Type an operator to fill the selected blank: plus, minus, star for times, slash for divide, equals. Arrow keys move between blanks, Backspace clears, Z undoes.

How to play

  1. Fill every blank tile with an operator so each row and column is a true equation. Equations read left to right or top to bottom only.
  2. Tiles where lines cross are shared — one symbol has to work both ways.
  1. Usual math order: × ÷ before + −. Division must come out exact.
  2. Harder levels add ^ power, . decimal point (3 . 5 is 3.5), % remainder, and < > for lines that are inequalities.

Keyboard: + - * / = ^ . % < >, arrows to move, ⌫ to clear, Z undo, P to pause.
