ShakaShaka vs Binary Puzzle

Draw one diagonal. Such a small move, and somehow your mind goes quiet. ShakaShaka is a solo slant logic puzzle guided by numbers. There are only three rules: draw a diagonal in every cell, make each corner number match how many diagonals touch that point, and never let the diagonals close a loop. That's all you need to know. Behind those simple rules is a genuinely satisfying challenge. No guessing, ever. Follow the numbers and the no-loop rule and every board resolves by pure logic, with exactly one solution. It's the "of course!" moment, again and again. HOW TO PLAY - Tap a cell to cycle its diagonal - A circled number on a grid corner is how many diagonals meet there - Numbers turn indigo when satisfied; diagonals in a loop light up red - Fill every cell, match every number, make no loops, and you're done FEATURES - Always exactly one solution, every board generated to be solvable by logic - Four sizes: Easy 6x6, Medium 8x8, Hard 9x9, Expert 10x10 - Daily puzzle: the same board for everyone, every day - Track your streak, puzzles solved and average time - Hints, undo and clear when you need them - Washi-paper look with indigo lines, plus Dark Mode - English and Japanese GREAT FOR - Sudoku and Kakuro fans looking for something new - Brain teasers on your commute or coffee break - Winding down with something calm before bed - Anyone who wants easy-to-learn rules with real depth PRIVACY - No account or sign-in - Your records stay on your device - Puzzles play offline - To show our other apps, the app may load public App Store information.
