Sizzling Kingdom™: Bison Review
This game presents innovations, showcasing the best this developer offers. A cosmic vibe is found in this release, set in a forest with lively animals on the 6x4 grid.
The wild animals move their heads slowly, as if they’re examining you. Examining this game, it was hard to find drawbacks. There are 3 main features: Wild Rampage, a Collect to Infinity™ Bonus Round, and the modifier-rich Hold the Jackpot feature. The max win is 5,000x, and the 96.12 % RTP is above average.
Sizzling Kingdom™: Bison Slot Features
The premium animal symbols pay between 2 and 30 x your stake for 6 of a kind wins, and the Bison Wild can appear in 4 different sizes to substitute for pay symbols. You can choose your preferred volatility and game speed from 3 settings in the game interface.
The Wild Rampage feature triggers when you land 2 full-reel Wilds, giving you 3 re-spins. The triggering wilds are sticky, and each new sticky wild resets the re-spins tally to 3. You can land Upgrade symbols during the Wild Rampage feature as well, and these upgrade the Grand Jackpot.
The Grand Jackpot is won if you fill all 30 positions with wilds, and the prize value increases per upgrade symbol you land. The Grand Jackpot pays 500x, 1,000x, 1,500x or 5,000x your stake, respectively, for level 1, 2, 3 and 4. If you don’t land the Grand Jackpot you get line wins from the wilds, and they pay 10x, 20x or 40x your stake for 4, 5 or 6 of a kind.
You need 3, 4, 5 or 6 silver coin buffalo scatters to trigger the Bonus Round, and this gives you 8, 15, 25 or 100 free spins. You can retrigger the feature the same way, but you also get +5 extra spins when you land only 2 scatter during the bonus round. All low-value symbols are removed during the feature.
Blue moon buffalo sticky cash symbols can appear anywhere, with values between 1x and 10x your stake. These symbols remain for up to 10 spins, and their values are only collected if you also land a Collector symbol. The Collect to Infinity™ symbols appear on the top row only, and they will persistently collect all cash values until the bonus round ends.
Sticky cash and collector symbols remain for up to 10 spins in the base game, and this increases your Hold the Jackpot chances. You need 6+ bonus symbols of any kind to trigger the Hold the Jackpot feature, but these symbols only pay in the bonus round or the Hold the Jackpot round.
The Hold the Jackpot round plays out on 30 single-position reels, and you start with 3 re-spins. Each new bonus symbol resets the re-spins tally to 3, and regular cash symbols come with values between 1x and 10x. There are plenty of special symbols to cover as well:
- Collector (top row only) - comes with a random countdown number of 1 to 10, and it collects all cash values on the column below until the countdown reaches zero.
- Collector modifier symbols (bottom reels) - adds +3 to the Collector countdown, or upgrades the Collector to Collect to Infinity.
- Cash Rain™ (top row only) - adds 4 cash symbols to the positions below, or it upgrades the value of existing cash symbols.
- Mystery symbols (top row only) - can turn into collector, cash, cash rain or level up symbols, and all mystery symbols are revealed at the end of the feature.
- Gallop symbol (bottom reels) - comes with random multipliers of 2x and 10x. The symbol takes the longest horizontal path, leaving cash symbols of the same value in its wake. It multiplies the value of any already present cash symbols.
- Level Up (bottom reels) - increases the Grand Jackpot one tier per symbol, up to the top-level 4 at best. The Level Up symbol turns into a 1x cash symbol after.
The feature ends when you either run out of re-spins, or you manage to fill all positions with bonus symbols of any kind. Your total win is then summed up, and if you fill all positions you win whatever level of the Grand Jackpot you’ve upgraded to during the feature.
The 200 Spins Sizzling Kingdom™: Bison Slot Experience
You get to see some smaller base game wins, before purchasing the Wild Rampage feature. Then the free spins feature, before purchasing the Hold the Jackpot feature.
Review Summary
This game is a highly engaging and feature-rich release. The pace is excellent, especially with the turbo switched on, and this is something many developers could learn from. There are several avenues that lead to the 5,000x Grand Jackpot.
The Wild Rampage feature is exciting, as you’re bound to rack up at least a decent wild payout, if not 1 of the 4 levels of the Grand Jackpot. The cash collect system adds an extra layer of excitement to the bonus round, but the big highlight is undoubtedly the Hold the Jackpot feature. It comes with plenty of modifiers, including the brand new Cash Rain™ symbol, and tension runs high when you’re closing in on the grand prize. Overall, a highly recommended installment.

| Wild Rampage w/ up to 5,000x jackpot | |
| FS w/ Collect to Infinity™ cash prizes | |
| Hold the Jackpot w/ plenty of modifiers | |
