Shark Park Slot Review

Thunderkick has Shark Park dated for November 2026, which is a bit of a weird time to release a summer beach slot. If the gameplay feels familiar, one reviewer would agree: they say it closely repeats Greedy Pumpking, a Thunderkick game dated about a month earlier. Still, it's built around roaming, merging multiplier wilds, which is a mechanic I usually enjoy.

To trigger the bonus naturally, you need three scatters in the base game, which gives you 8 free spins (any extra scatters that land during the bonus will add one more spin). The nice thing here is that any multiplier wild sharks on your screen when the bonus triggers carry over, and every shark on the board during the free spins sticks around for the rest of the round.

The sharks carry multipliers of x2, x3, x5, or a massive x100, and the way they interact is where the game gets interesting. If two or more sharks are part of the same winning cluster, their multipliers multiply together. However, once that win pays out, those same sharks move to empty spots and merge, adding their values together into a single larger shark. The real money is in getting them to share a cluster, not in the merge itself.

If you don't want to grind the base game, you can pay 1.5x or 2.5x your bet for Bet+ Bonus Boost or Bonus Boost Plus to make a trigger more likely. If you want to buy straight in, you have three options: 80x your bet for Into The Blue, the standard round, 200x for Beneath The Surface to start with a small shark, or a hefty 500x for Blood In The Water to guarantee an x100 shark right from spin one.

I went for Blood In The Water at 500x, and it gave me a very clear picture of how volatile this game is. My x100 shark swallowed a few smaller ones, growing to x104 and eventually x109. When it connected in a cluster with an x3 shark, the multipliers multiplied to x312, giving me a nice 124.8x payout on a single win. Later, it paired with an x2 for a 100x win.

But here's the frustrating part: if a shark isn't part of a winning cluster, it does nothing. For about half of my free spins, my massive multiplier just sat there looking pretty while clusters formed on the other side of the board. I ended up winning back just under my 500x buy-in. It's a harsh reminder that a big multiplier doesn't guarantee a massive payout. (The game caps at a 10,000x max win, at which point the round ends).

To be completely fair to Shark Park, you have to look at the math, and this is where it struggles a bit. The RTP sits at a pretty low 94.14%. The closest comparison math-wise is ELK Studios' Cluster Kingdom, which has the same 10,000x max win and a 94.00% RTP, a hair below this one.

However, a lot of competing games offer better returns. AvatarUX's Tempting Treats (due in October) and Backseat Gaming's Monster Munch Stacks both share the 10,000x potential but boast much friendlier RTPs around the 96% mark (though their mechanics differ slightly, AvatarUX leaves multipliers on grid spots, and Backseat strips the board to coins).

Other studios also use the x100 wild concept, like Hacksaw's Demonic Dolls (96.26%, due in October) and Pragmatic Play's Snow Party (96.50%), but in those games, the multipliers add together rather than multiply. If you specifically love the multiplying wild mechanic, Pragmatic's Buffalo King Megaways does it during free spins with a better 96.52% RTP, though you are trading off for a lower 5,000x max win.

Shark Park is a fun slot when the clusters line up perfectly, but the low RTP and dead spins during expensive bonus buys mean you should approach it with caution. It's a solid game, but it doesn't quite beat out the competition math-wise.
