Paylines explained
These are also referred to as betting or winning lines. These are the sequences of reel symbols that secure you a win. Old-school physical slots had just one pay line, so players would aim for three symbols matched horizontally. Today, pay lines may go in zigzag or other directions. The value of each is specified in the paytable for the slot.
Modern slots may offer up to three dozen pay lines. If there are five reels, a pay line will feature five symbols. There must be six symbols for six reels, etc. Different combinations bring different rewards. You may get a prize, a bonus, a multiplier, or a number of free spins.
