Description
Calc Ninja is a mental-math battle puzzle. Fill the blanks in each equation to strike down the oni!

How to play
1. Each battle shows an equation with blank tiles, e.g. ( □ + □ ) × □ = 18.
2. Tap number tiles to fill the blanks so the equation is true.
3. A correct answer strikes the demon; a wrong answer or running out of time lets it strike you.

Content
- 30 scrolls across 6 ninja ranks (Shoden to Gokui)
- 16 unique oni bosses with a demon gallery
- Operators and parentheses stay fixed. You only place the numbers, so it is pure mental math.

Great for
- Adults who want daily brain training
- Anyone who likes number puzzles and quick arithmetic
- Fans of a Japanese ninja-and-oni theme

Free to play. No account required.
