Each Win line has one unit of the stake associated with it, each line can win separately in any single game. The icon on the far left of the win line will act as a point of reference for finding at least two further matching icons as you move along the line towards the right. Win lines will always pay from left to right only.
You have the opportunity of choosing up to 20 win lines per game. The stake is fixed for this game, but you can select how many win-lines to play with by either pressing the Lines button or the line indicator buttons (colour coded 1-20, situated on each side of the reels).
