Holy Moo! Extreme Power Slot by Play'n GO

Wins don't just pay and vanish. Every winning cluster leaves a glowing Bovine Frame sitting on its position, and those frames hold for the rest of the spin waiting for a Collector to show up. If no Collector lands by the time the cascades stop, the frames clear and the spin ends like a normal scatter-pay round. If a Collector does drop in, every framed cell snaps into a Cash Symbol worth 0.5x to 10x your bet, and the Collector hoovers up the lot in one pass.

There are six Collector forms, and you have to earn them. The Bovine Path is a 6-stage tracker that fills one notch every time a Collector lands. Stage one is plain Collect, the basic vacuum. Stage two upgrades to Spread & Collect, which expands the frame footprint by 2-4 extra cells before sweeping. Stage three is Multiply & Collect, applying multipliers to 3-5 cash values so each one effectively pays twice. Then Collect & Collect summons fresh Cash Symbols into frames and pulls those too. The last two stages are Spread More and Multiply More, escalating the same tricks to 4-6 frame additions and 5-7 multipliers respectively. Once you've unlocked all six, the path is done and every future Collector just feeds the side feature.

That side feature is MOO-IGHTY ZEUS, the cartoon Zeus-bull who stands left of the grid on a fluffy cloud, lightning bolt in hand. Each Collector he absorbs pumps his power gauge, and he randomly fires one of four bonus prizes: 20x for the MINI, 50x MAJOR, 100x MEGA, or 1,000x GRAND on the total stake. It's a base game feature only. Free Spins don't get him.

Free Spins land on three Moolympus pillar scatters. Three regular scatters give you the standard round where frames persist across cascades until they pay out. If one of those three is a Super Scatter, you get Olympian Spins instead, the same engine but with frames that stick around for the entire round rather than emptying spin by spin. Only the Collector forms you've already unlocked in the base game can appear during either bonus, so a fresh session triggering Free Spins early on a flat Bovine Path is a much weaker payday than a triggered round after you've already worked your way up.

The art is pure cartoon Olympus with a herd of cows. Pastel cow-bull faces in laurel crowns and Greek robes fill the high-symbol slots, card royals carry the low-pay floor, and the whole grid is dropped inside a pale Greek temple pediment under a star-flecked night sky with glowing teal mountains and floating cloud pillars in the distance. The four jackpot banners hang above the temple in golden ribbons. It's the same playful tone Play'n GO leaned into with their Rise of Olympus series, just swapping the serious mythology for a pun-heavy bovine reskin.
