The paylines in slots are quite a simple concept. The most basic aspects of a game in the slots genre are the reels and symbols. Depending on how the reels stop and which symbols are shown at that moment, you may or may not form winning combinations. But how does the game determine which combinations will provide you with a payout and which won’t? This is where paylines come in. A payline is a pattern on the reels which the game reads to see whether you score a winning spin or not. Paylines start from the leftmost reel and continue along the adjacent ones until they reach the rightmost reel. Some can a straight line while others are zig-zagged.
