## What is Loop Sum?

A simple logic puzzle: select numbered squares so their sum equals the target.

[Rules]
- Tap bright numbered squares to select them (dark squares cannot be selected)
- Make the sum of the selected numbers equal the target shown at the top
- The selected squares must form one group connected edge to edge (up, down, left, or right)
- The selected group must not enclose any unselected squares (no holes)

When all the conditions are met, “Solved!” appears automatically and the next puzzle begins.
While you play, the bottom of the screen shows what still needs fixing, such as how far the sum is from the target or what is wrong with the shape.

[Features]
- A guided tutorial for first-time players: just tap the glowing squares
- 24 puzzles (3 difficulty levels, 8 each)
- No ads, no in-app purchases, and no data collection
- Play completely offline
