Sumo Supreme Megaways Slot by Pragmatic Play

A weight-based trigger system sits underneath the Megaways grid. Every regular symbol carries a weight value, and each spin sets a random target number between 11 and 40. Five boxes below the reels track how much weight has accumulated on each reel. When a reel's total hits the target, its box cracks open and delivers one of three prizes: a cash award between 0.5x and 500x bet, a multiplier of 2x to 5x applied to that tumble's wins, or expanding wilds that fill every position on the reel.

The target drops by 1 after every tumble, not just every spin. A long tumble chain pushes the target lower and lower, making the remaining boxes progressively easier to open. If all five boxes trigger during a single spin, the final box pays out all three prize types at once - cash, multiplier, and a full column of wilds.

Free spins set one target weight for the entire round, and it keeps shrinking with every tumble across all spins. By the late rounds, the target sits so low that boxes open almost immediately. The round starts with 8 to 28 spins depending on how many scatters triggered it (4 through 9+), and 4 additional scatters during the round add 4 more.

Colossal sumo wrestler symbols occupy up to 3x3 positions on the grid, creating dense way clusters when they land across multiple reels. The tumble mechanic clears winners and drops fresh symbols into the gap, feeding the weight system while chasing the declining target.
