Sum logic puzzle · Classic · Daily · Rush

Android (Coming Soon)

Keepsum is a logic puzzle about sums. Every number on the board is either kept or erased. Keep the right ones so that every row and column adds up to its clue. Circle the numbers to keep and erase the rest. A line that adds up gets a check, and when the numbers you kept already make a clue, tap it to erase the rest of the line at once. Every puzzle has exactly one answer, and you can always reach it step by step. No guessing needed.

Key Features

• Hints that explain why A hint first shows which line to look at, then the cell to decide and the reason. It also finds cells that don't match the answer, so you learn the logic instead of guessing.
• No lives, no pressure A mistake never ends a puzzle. Hints and undo are free and unlimited in Classic and Daily.
• Optional helpers Show current sums, erase the rest automatically, show mistakes, a row and column guide and large numbers. You can also drag to mark a whole row or column in one stroke.
• Paper-and-pencil feel Paper-and-pencil sounds, gentle animations and vibration. Turn off any effect you don't want, or reduce them all.
• Offline play No sign-up, no login. The game works without an internet connection.
• Multilingual English, Korean, Japanese and Chinese (Simplified and Traditional), following your device language or your choice in Settings.
