## What is Sumnum?

Sumnum is a clean number puzzle with one rule: select cells in the grid so
that every row and column adds up to its target.

Each puzzle has exactly one solution - no guessing, just logic.

HOW TO PLAY
Tap a cell to select it or mark it as discarded. Get every row and column
sum exactly right to win. Made a mistake? Undo as many times as you need.

FEATURES
• Daily Puzzle - a fresh challenge every day with streak tracking
• Three difficulty levels: Easy (5×5), Normal (7×7), Hard (9×9)
• XP and leveling system - earn experience with every solve
• Full undo support
• Per-difficulty stats to track your progress

If you like Sudoku or Kakuro, you'll feel right at home.
