About Sumzo
A block puzzle for numbers people.
Sumzo takes the drag-and-drop block puzzle you know and gives every tile a number. Rows and columns clear when their tiles add up to exactly the target shown on the edge of the board.
Positive and negative tiles, combos for clearing several lines at once, and a difficulty curve that grows the numbers as you improve — simple rules, deceptively tricky puzzles.
