🔥 Streak: 0 • 🏆 Best: 0

📖 How to play

• Tap an empty cell, then a number on the keypad.
• Hold a number to jot a small pencil note in the cell (⌫ erases the notes).
• Each number appears only once per row, column, and box.
• Wrong guess? It flashes red and adds 1 mistake — 3 mistakes end the game.
• Be quick: your score starts at 1000 and drops 3 per second (and 50 per mistake).
