## Description

Solve a daily CrossSum puzzle with number logic, addition, training boards, progress stats, themes, and reminders.

CrossSum is a clean number puzzle game built around addition, logic, and focused daily practice.

Fill each blank cell with a number from 1 to 9. Every connected row or column segment must add up to its clue, and numbers cannot repeat within the same segment. The rules are simple, but every board rewards careful thinking.

Features:
- Daily puzzle: a fixed challenge for each day
- Training mode: practice boards from 5x5 to 8x8
- Progress stats: track completions, time, and practice history
- Theme colors: personalize the look of the app
- Daily reminders: set a time to keep your puzzle habit going
- Offline play: open the app and solve whenever you like

If you enjoy number puzzles, Sudoku, Kakuro, math games, brain training, or logic challenges, CrossSum is designed to be a quiet daily puzzle you can return to anytime.
