About game
🧩 An addictive logic puzzle with simple rules and a difficulty that grows level by level.
🎯 Your task is to connect every number in order and draw one unbroken line through every cell of the board. Sounds simple — but finding the right route gets harder with every level!
🧠 Hundreds of levels and daily challenges — a proper workout for the mind!
🏆 Tournaments and a global leaderboard — compete with other players.
😌 Clean design, comfortable controls and short levels make it a great pick for a quick break or a calm bit of logic practice. Take the levels at your own pace and enjoy the moment the line fills the board perfectly.
How to play
— Start at number 1. Swipe or click adjacent cells to draw the line. On desktop, you can also use the arrow keys.
— Visit the numbers in the correct order: 1 → 2 → 3, and so on until the final number.
— The line can move only up, down, left, or right. Diagonal moves are not allowed.
— By the time you reach the final number, every cell on the grid must be filled.
— The line cannot pass through walls, so you will need to find a way around them.
— Made a mistake? Drag your finger or cursor backward along the line to erase part of it. You can also tap or click any previously filled cell to return to it instantly.
— Stuck? Use a hint to reveal the next correct move.
