Monster Quest (BTG) – Fighting for Multipliers and 99,900x Max Win

Big Time Gaming (BTG) is taking the standard Hold and Spin mechanic and turning it into an active combat zone. In Monster Quest, dropping coins into empty slots is no longer enough; you have to physically match or beat the value of the symbols dropping onto the screen to collect them. Scheduled for a June 24, 2026 release, this slot swaps passive collection for an RPG-style progression loop, all while teasing one of the highest payout ceilings in the studio's history.

Here is exactly how the combat mechanics, the custom betting options, and the massive max win stack up against the rest of the studio's portfolio.

The Math

The core draw of Monster Quest is its towering 99,900x maximum win. To put that ceiling in perspective, it mathematically beats out recent heavyweights like Fruit Merge Megapots (90,335x) and Monopoly Megapots (98,850x), sitting just below the extreme 133,100x cap found in White Rabbit 2. Because this payout potential is so high, BTG has strictly capped the maximum bet at just €10.00 per spin.

As always with BTG’s "Very High" volatility models, you need to watch your bankroll, but you also need to check the rules. While the optimal RTP sits at 96.58%, casinos can drop the payout profile down to 94.41% or even a brutal 86.35%.

Combat Hold and Spin

In standard games like Big Bucks Deluxe, a collector symbol simply sweeps up everything on the board unconditionally. Monster Quest changes the formula entirely. Triggered by landing five or more Monsters and Dragons alongside the Knight symbol, the feature turns the Knight into an active fighter. He only collects the cash values of Monsters with a lesser or equal value to his own.

You start with three lives, losing one if a spin yields no new Monsters or if a Monster is too strong to defeat. Slaying a beast absorbs its value, leveling up the Knight so he can eventually take on the ultimate prize: the Dragon.

Free Spins

Landing three Scatters triggers 12 Free Spins. During this round, the Knight stays on the board permanently, starting with a random base value between 8x and 15x your stake.

This is where the math gets deeply tied to the theme. In legacy Megaways games like Bonanza or Extra Chilli, your unlimited win multiplier goes up by +1 every time you get a cascading win reaction. In Monster Quest, your multiplier only increases by +1 when the Knight slays a Monster. Every beast he takes down boosts your multiplier for regular line wins, while also instantly adding its cash value to your total payout.

Bonus Buys

If you prefer to skip the base game, BTG has provided a few flexible ways to buy into the action:

• Hold & Spin Buy (35x): You can buy straight into the combat feature for an accessible 35x your stake. This is the exact same golden standard price point used in Fruit Merge Megapots and Monopoly Megapots.
• Free Spins Buy (90x): Historically, BTG prices its Free Spins at a flat 100x your stake, like in The Race or Big Bucks Deluxe. Here, you get a slight discount, grabbing the 12 Free Spins for 90x your stake.
• Power Play (8x per spin): If you want to grind the base game but want better odds, you can turn on Power Play. For a premium of 8x your stake per spin, the game guarantees a minimum of 10,000 Megaways on the board every time you hit the button.

Final Thoughts

Monster Quest is built for players who want a highly interactive slot session. By forcing your collector symbol to actively defeat enemies to absorb their values, BTG has introduced a level of progression rarely seen in standard Megaways titles. The 99,900x ceiling is elite, and the discounted 90x Free Spins buy-in gives you a cost-effective way to chase it.
