Instead of spinning rows, grid slots have a large grid of symbols – often 5×5 or bigger. Most have a cascading mechanic that sees new symbols drop in (like a cascading waterfall), giving you multiple chances to win from a single spin. Many slots include extras like wilds, multipliers, or cascading reels that can trigger on any spin and boost your winnings. Games like Starburst are known for expanding wilds, while Gonzo’s Quest features cascading wins that increase with each drop. Gates of Olympus Super Scatter is a recharged version of the original, raising the top win from 5,000x to 50,000x. You get tumbling reels that keep wins coming back-to-back, random multipliers up to 500x that boost any spin, and a free spins round triggered by four or more Zeus Scatters.
