As with the slot’s predecessor Starburst, Berryburst is all about the wild symbols. As is usually the case, a wild will substitute for any other symbol to complete or add to a winning combination, but this wild is much busier. When it lands, the wild symbol will immediately expand to fill a full reel, and any combinations it creates will pay out. The wild will then lock in place for a respin, again with any clusters paying out as normal. If a new wild lands on this respin, that will also expand, and both wild reels will lock in place. This will continue until no new wild symbols land. This means you could end up with five fully wild reels to trigger the slot’s max jackpot of up to 5,000x your bet.
