ShakaShaka: Slant Logic Puzzle

About this app

Draw a single slant. Such a small move—and somehow, a quiet focus settles in. Naname is a solo logic puzzle solved by numbers. The rules are just three: put a diagonal in every cell; match each corner number with how many slants meet at that point; and never let the slants form a closed loop. That’s everything you need to remember. Behind those simple rules is a real, satisfying challenge. No guessing required—follow the numbers and the no-loop rule carefully, and the answer is fixed by logic alone. And there is always exactly one solution. Filling the board with “ah, of course” instead of “maybe this” is what makes it click. If sudoku has started to feel a little familiar, this is a gentle next step. ■ How to play - Tap a cell to cycle its diagonal - A number on a grid corner is exactly how many slants meet there - Finish so no slants join into a loop - Solve it when every number matches and there are no loops ■ Features - Simple rules, deep logic—always a single solution - Four sizes: Easy 6x6, Medium 8x8, Hard 9x9, Expert 10x10 - A daily puzzle, identical worldwide by date, no server needed - Endless auto-generated boards—next one is always ready - Quiet records: streaks, solves, and times - A hint for when you’re stuck - Washi-paper look with indigo lines—calm and easy on the eyes - English and Japanese ■ Great for - Anyone looking for the next puzzle after sudoku - A few focused minutes on the commute or a break - Winding down with something quiet before sleep - People who’d rather avoid ad-heavy, cluttered apps ■ Privacy & peace of mind - No account needed - Your records stay on your device - Plays fully offline
