Thirty logic puzzles in one app. No words, no lives, and never an ad inside a round. PUZZLES THAT NEED NO LANGUAGE Every board is numbers, shapes and colour. There is nothing to read, in any language — so the same puzzle works whoever you are. Sudoku, Nonogram, Minesweeper, Kakuro, Shikaku, Futoshiki, Skyscrapers, Star Battle, Bridges, Fillomino, Calcudoku, Numberlink, One-Stroke, and seventeen more. MISTAKES COST TIME, NEVER A LIFE An error adds five seconds to your clock. There are no hearts, no lockouts, and nothing that can stop you mid-puzzle. You always get to finish the board you started. ONE BOARD A DAY, THE SAME ONE FOR EVERYONE Everybody plays the identical daily puzzle. Your time means something because the board is the same, not because anyone was asked to be honest about it. DUELS ON THE SAME GRID Send a friend the board you just played. They get that exact grid and the same clock, and you both see the two times side by side. There are no bots — when nobody is around, the app says so rather than inventing an opponent. EVERY LEVEL CERTIFIED Each puzzle has exactly one solution, checked before it ever reaches you. Difficulty only rises, one level at a time, so the ladder always makes sense. PLAYS OFFLINE, NO ACCOUNT The whole game is on your device. Nothing to sign up for, nothing to create, no email to hand over. Four themes, day and night, in English and Turkish.
