Sizzling Kingdom Bison: Hold the Jackpot Slot

Wild Symbol

The Bison is the Wild symbol which substitutes for all other symbols except for the Scatter and Bonus symbols.

Wild Rampage Feature

If you land two big Wild symbols when you spin the reels, you'll activate the Wild Rampage feature. At first, you'll get three chances to spin again, but each time another Wild symbol appears during the bonus game, you'll reset back to three spins. The Wild symbols that show up during the Wild Rampage feature will stay in their places.

If you get a Level Up symbol, your current Grand Jackpot level will increase, and the symbol will then turn into a Wild symbol.

When the feature ends, the value of all the Wild symbols on the grid will be calculated and paid out. However, if you manage to fill all 24 positions with Wild symbols, you'll win one of several jackpot prizes. The size of the jackpot payout depends on the level you've unlocked. It's important to note that when you win the jackpot, all other winnings will be cancelled.

Free Spins Bonus

When you manage to hit three, four, five, or six Scatter symbols anywhere on the reels, it will activate the Free Spins Bonus. Depending on how many Scatter symbols you hit, you'll receive eight, 15, 25, or 100 free spins.

If you land two or more Scatters during the Free Spins Bonus, you can re-trigger the feature and get even more free spins! During the free spins, you'll only see high-paying symbols and special symbols on the reels.

Sticky Cash Symbols

If you come across Sticky Cash symbols while spinning for free, they will stick to the reels for the next 10 spins. But here's the catch: you can only accumulate the values from Sticky Cash symbols and regular Cash symbols if a Collector symbol appears on the top row.

Don't worry, though, because the Collect to Infinity feature is already active during the free spins. That means the Collector symbols will keep gathering values until the bonus round comes to an end.

Hold the Jackpot Bonus Feature

When you manage to land six bonus symbols of any kind while playing the base game, it will activate the bonus feature. This brings an extra reel into play, expanding the game to 30 tiles instead of the usual 24.

The bonus symbols become sticky, meaning they stay in place during the bonus game. At the beginning of the bonus feature, you'll be given three re-spins. Each time you land a new bonus symbol, it resets the number of re-spins back to three.

During the bonus round, there will be various modifier symbols which can land and each one has a different function.

If you're able to fill all 30 positions with bonus symbols of any type, you'll win the Grand Jackpot. The size of the jackpot prizes depends on the levels you've unlocked, with a maximum win of 5000x the stake at level 4.

Our Verdict: We were very impressed with the sheer magnitude of bonus features in this slot game, and there was never a moment that we found ourselves bored. There were some instances where we had just finished the free spins feature and we hit the bonus feature on the very next spin.
