It has five kinds of lines to choose from, corresponding to their respective color marks. Starting from the first line, three or more scattered symbols appear at the same time, which will trigger a free game. The number of free games is determined by the number of scattered symbols.

You must keep a positive attitude when playing such games, especially online games. There is not much external pressure for you to leave the game that always loses money.
