Description by NOBORU ISHIKURA Written by the developer, not by AppBrain. Click to read.
Kyouen (共円) is a geometric concept describing four or more points that all lie on a single circle.
"Tsume Kyouen" is a puzzle game where you find the combination of stones that satisfies this condition.

Select four stones from those placed on the board and find the "kyouen" — the arrangement where all four lie on a common circle. The rules are straightforward, but as the board grows more complex, spatial reasoning becomes essential.

Features
- A mathematical puzzle grounded in geometry
- Over 10,000 stages with varied challenges
- A clean design that keeps the focus on the puzzle
- Save and sync your progress with account sign-in

Great for fans of mathematics, geometry, or logic-based puzzles.
