Each slot machine comes with its own amount of pay lines, ranging from one to up to a million. However, once the stage is set, the gameplay of all spins tends to feel pretty predictable unless you trigger a lucky bonus game. Not so for Megaways, as all spins come with a varied amount of symbols per reel (column) and, as such, a varied number of pay lines. Standard Megaways have 6 reels which can each vary between 3 and 6 symbols per reel. That means you can have 729 (3x3x3x3x3x3) lines one spin and 117,649 lines just a few spins later! This unpredictable element adds a lot of fun to Megaways games but also means winnings are a bit more unpredictable than in most other slots. The win potential is very high, but dry spells aren't uncommon. That is why you should be inclined to bet slightly less on Megaways than you would bet on other types of online casino games.
