Yokozuna Clash Slot by Yggdrasil Gaming

The bonus does not run on a spin counter. Land 2 trophy scatters on reels 1 and 5 simultaneously and the Tournament Free Spins begin, but the round lasts as long as a 7-step power meter holds. Wins from the left edge push the opponent one direction, wins from the right edge push him back the other. Tie spins where both directions pay sit at zero motion. The bonus only ends when somebody gets shoved out of the ring entirely. There is no minimum spin count guarantee and no maximum either, which means a clean run of left-only wins can vault straight into the Final Fight while a streak of right-side hits ends the round in three or four spins.

The opponent in the Semi-Final is randomised between two characters, and beating him unlocks a second tier against Yokozuna himself. That second fight is harder. The red demon sumo pushes back four bars per losing spin instead of three, but his hits also throw 2-4 random wilds and a x2-x4 multiplier onto the same spin that just hurt the player, so being on the back foot still pays. Defeat him and the entire Free Spins total doubles before payout.

The base game runs 243 ways evaluated from both directions, which is unusual at this ways count. A 3-of-a-kind cluster of phoenix on reels 5, 4 and 3 pays the same as the same combo on reels 1, 2 and 3, effectively letting two combos land on the same row from each edge. Two cartoon sumos squat below the cabinet between spins and randomly trigger small enhancements, the blue Riku adding 1-2 wilds on the middle reels and the green Haru stamping a x2 or x3 multiplier on the spin output.

One quirk worth flagging applies inside Free Spins only. Any 5-of-a-kind win triggers the Sumo Clash extra-symbols rule, dropping 2-4 additional copies of the winning icon onto the grid in positions that don't overlap the original combo or any wilds. The extras then pay as if they were always there. The visual setting is a Japanese dojo, animal portraits set inside ornate metallic medallions, the cabinet sitting against a curtained stage with rope barriers and a silhouetted crowd in the haze.
