How to play
Let the equations cross-check each other.
Fill every highlighted square with a single digit. Horizontal and vertical equations share digits where they cross, so one good number can unlock several lines.
Use Check once every blank is filled. It marks only the cells that need another look and never gives away the answer.
Keyboard friendly
Tap a cell or stay on the keys
Select a blank with a click or tap, then use the keypad or number keys. Arrow keys move to the next blank in the chosen direction; Backspace and Delete clear the selected cell.
