How It Pays / Megaways Grid

This slot runs on a 6-reel, 7-row grid that expands and contracts with every cascade. The Megaways engine means paylines shift from spin to spin – up to 117,649 ways to land a win. Symbols tumble down (cascading reels), and when a win forms, those symbols vanish to make room for fresh drops. The mystery symbol – a shadowy background image – transforms into matching symbols during the base game, injecting extra volatility into ordinary spins.

The slot is medium volatility. Base game wins are modest, but the real money lives in the bonus. When free spins land, players don’t just spin and hope – they pick their mode first.

Free Spins Modes / Multiplier Progression

Free spins is where this slot shows its teeth. Players choose from four distinct modes, each with a different spin allocation and multiplier starting point. The multiplier climbs with every consecutive win during the feature – and there is no upper ceiling. Land a win, the multiplier rises. Land another, it rises again. This progressive multiplier can balloon across a single free spins session, which is why the x10,000 max win is locked into the bonus, not the base game.

Trigger free spins → pick your mode → watch the multiplier climb as cascades keep firing. That’s the core loop.

RTP / Bonus Buy

Activate the bonus buy feature and the RTP ticks up to 97.1% – the headline figure. Bonus buy lets players skip the wait and jump straight into free spins, though the cost varies by operator. This is a sharp tool when the base game feels flat or the free spins trigger seems distant.

Bet Range / Max Win

Minimum bet is 0.1 and maximum is 10 per spin. The max win ceiling is x10,000 your stake – a solid multiplier for a medium-volatility slot, though the bulk of that upside lives in the free spins multiplier stacking, not random base game hits. The game file is 14.7 MB and runs on HTML5 / JavaScript across desktop and mobile.

FAQ

What is the RTP of Bison Rising King?

The base game RTP is 96.5%. When players use the bonus buy feature to trigger free spins directly, the RTP rises to 97.1%. Both figures are solid for a medium-volatility Megaways slot.

How high can the free spins multiplier go?

There is no upper limit. The multiplier climbs with every consecutive win during the free spins feature. In theory, it can grow very large if cascades keep landing - which is why the x10,000 max win is anchored to the bonus, not the base game.

Can I choose which free spins mode to play?

Yes. When free spins trigger, players select from four distinct modes. Each mode offers a different spin count and multiplier starting point. This choice mechanic is one of the slot's defining features - no auto-spin into a preset mode.

What does the mystery symbol do?

The mystery symbol appears as a shadowy background image during the base game. When it lands, it transforms into a matching symbol to help complete wins. It's the primary wild-like mechanic in the base game, adding texture to ordinary spins between bonus triggers.

What is the max win and max bet?

Max win is x10,000 your stake. Max bet per spin is 10 (minimum 0.1). The bulk of the x10,000 upside comes from free spins multiplier stacking, not base game hits alone.

Reviewed by Marcus Reynolds – Senior Game Analyst

Editorial rating: 4.3/5

this slot is a well-built Megaways slot that leans on player choice and multiplier depth rather than flashy base game mechanics. The mystery symbol keeps the grid interesting, but the real game is in free spins - where the uncapped multiplier can spiral into serious wins. Medium volatility and a 97.1% RTP on bonus buy make it a solid mid-range option for players who don't mind waiting for the bonus.
