About
Draw a line. Hit the target. Keep going.
Line Sum is a calm, clever number puzzle. Drag your finger across the grid to connect numbers and operators into a path that equals the target. Get it right and those cells are cleared, fresh ones drop in, and a new target appears. There is no end, only your best run.
