No annoying ads, no data collection. Endoku is a single-player logic puzzle played on concentric rings, where you place numbers so each radial line adds up. Just two rules: • Each ring uses its set of numbers exactly once. • The cells along each radial line must add up to the same target. From these two simple rules, pure logic — never guessing — leads you to the one solution. Every puzzle is generated to be solvable by logic alone. Fresh for anyone who bounced off Sudoku, and meaty enough for anyone a little bored of it. Features: • Four board modes: Intro (2 rings) / Basic (3) / Advanced (4) / Expert (5) • Three difficulties (Easy / Medium / Hard) • Pencil marks (candidate notes) to work through the tougher boards • A fresh Daily puzzle with a calendar and streaks • A built-in strategy guide • Calm music and satisfying sound effects (each toggleable) • Gentle haptics • A calm, easy-on-the-eyes board • Japanese / English, portrait & landscape Intro and Basic (Easy/Medium) are free. A single one-time purchase unlocks all modes and difficulties, daily puzzles, the strategy guide, and music & sound.
