How to Play

Start from the chosen starting point. Draw a line, connecting the cells of the field to fill them. Avoid obstacles and plan the route so that the line does not break. Complete the level by filling the entire field without gaps.

Start slowly and look for the easiest match, path, or clue before making risky moves.
Use the first minute to understand the board layout instead of rushing through guesses.
If you get stuck, step back and scan corners, repeated symbols, empty spaces, or blocked pieces.
