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 1xbet apk download (like a cascading waterfall), giving you multiple chances to win from a single spin.

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.
