Big Sumo Slot by Playtech

Rice on the outer reels plus a Big Sumo on reel 3 sets off the main event: five spins on a widened 5x5, 50-line board where the wrestler does the eating. He starts dead center. After each spin pays its lines, he hops across to every Rice symbol on show and swallows it, and each one feeds a Rice stack. Fill that stack and he swells to cover more positions, the counter empties, and a spin drops back onto the clock. Keep feeding him and he can balloon until he fills a whole reel window, which hands you Mega Reel spins worth 70x, 100x, 150x, 200x or 350x your bet. The number of Rice that triggered the round sets where the stack begins, so a fatter trigger means a shorter climb to the first growth.

The base game is a plain 25-line affair next to that. Two wilds carry it. A standard SUMO wild lands across reels 2 through 5, while the BIG SUMO wild only turns up on reel 3, and that reel-3 sumo is exactly what you pair with the Rice to open the feature. Premiums are dojo props cut as round wooden tiles, an orange taiko drum, a green war fan, wooden geta sandals and a stack of hanafuda cards, with carved card royals doing the low-end work.

Then there are the progressives. Gold Triple Way scatters land on reels 1, 3 and 5, Silver on reels 2 and 4, and three or more anywhere drops you into the Triple Way round. Each symbol spins its own little reel, and if those resolve into three matches a super reel decides whether you walk off with the Grand Way, Major Way or Minor Way jackpot, seeded around 100,000, 10,000 and 1,000. All three sit in a purple panel down the left, tagged with red, green and blue gems.

A cart button buys the Big Sumo Feature outright if you'd rather skip the wait, and a lightning toggle bumps your trigger odds for a higher stake. It all plays out at a sunny cherry-blossom dojo, tiled training hall behind the reels, with an angry topknotted sumo glaring in from the side and his rival slumped nearby, cheerfully shovelling rice.
