🔥 DAILY PUZZLE
A new board every day, the same for every player. Keep your streak, beat your best time and share your result without spoiling the solution. Play 10 days in a row to earn a streak saver that covers you if you miss a day. Missed a puzzle? Play it from the calendar.
🧩 100 LEVELS, STEADILY HARDER
The first ones teach you as you play. Then the help fades away little by little, until the final levels, where it's just you and the board.
🎛️ CUSTOM MODE
Pick the size (4×4 up to 9×9) and the difficulty, then add any extras you like: Timer to time yourself, Chain to keep the boards coming, and Blind to play without seeing the line.
