Shark Wash Slot by Relax Gaming

Wilds in Shark Wash arrive carrying a number between 1 and 5, then refuse to leave. Each time the wild participates in a winning combination it counts down by one, and when it hits zero the original counter value gets banked into a circular Wild Meter that sits left of the reels. Hit the right cumulative totals and the meter unlocks a persistent multiplier - x1, then x2, x3, x4, and x5 at the top. Once a tier is revealed it sticks for the rest of the round, applied to every payout from that point forward. That single rule explains why otherwise quiet base spins can suddenly turn productive.

The wilds only land on reels 2, 3 and 4, which keeps the trigger geometry honest. Cascading reels do the rest: every win clears the contributing symbols, new ones drop in, and the wild's counter ticks down on each cascade it touches. When that counter empties, the wild detonates and triggers a respin, and respins keep chaining as long as fresh wilds keep destroying themselves. The collected meter progress carries across that entire respin sequence.

Free Spins arrive on three or more pink Bonus scatters. Three pays seven spins, four pays ten, and five pays fifteen. Extra Bonus symbols landing during the round add +1 spin each. Critically, the Wild Meter does not reset when free spins start - whatever multiplier you walked in with stays active, and the collector keeps filling. That makes the entry condition matter as much as the trigger itself.

If patience runs thin there are two purchase routes. Buy Free Spins is fixed at 80x bet and guarantees three Bonus symbols on the trigger spin, with a slightly different math profile than the organic trigger. The alternate Bonus Reels Mode strips paying symbols out of the reel pool entirely and only allows Bonus, Super Bonus and blanks to land, weighting the trigger odds differently for a different price.

Visually the cabinet sits inside a stone-frame portal on the seabed, surrounded by orange and purple sponge corals and waving kelp. The high pays are smiling cartoon sharks in diving masks, crabs, pufferfish and yellow fish, while the low pays are gem-shaped corals styled as card-suit shapes. The whole thing reads more family cartoon than predator menace, closer in tone to a Saturday morning underwater short than to anything you'd expect from a 5,000x cap. Compared with stablemates like Fisherman Slam, the math here is built around that sticky countdown collector, not the hook.
