Ranked #69 of 100 biggest max win slots
Big Time Gaming sends a lone knight through castle grounds to hunt down monsters for their loot in Monster Quest, a fantasy-themed release built on a six-reel Megaways grid capable of throwing up to 117,649 ways to win. The stronghold setting mixes stone battlements with a torch-lit arena and a moonlit version of the same grounds for free spins, and monster characters only show up as symbols on the reels rather than roaming the scenery.
Each reel drops two to six symbols per spin, and wins form from matching symbols landing on adjacent reels from the left. Card ranks nine through ace fill the bottom of the pay table, worth 0.4x to 0.6x the bet for six of a kind, while four crystal symbols make up the higher-paying set, worth 1x to 20x the bet. A wild substitutes for everything except scatters and bonus symbols.
Two bonus rounds carry Monster Quest forward: Hold and Spin and Free Spins, both purchasable individually. Hold and Spin triggers when six or more bonus symbols land, which can be a Dragon, a Knight or Monster icons. The Knight begins with three lives and spins the remaining grid positions for blanks or Monsters; a life is lost on any spin where no Monster lands and none are defeated, though defeating a Monster restores a life up to the cap of three. The Knight moves across the grid taking out Monsters of equal or lower value and banking their worth, and the round closes when the Knight runs out of lives, Monsters cover every position, or the Dragon itself is defeated - at which point the Knight's accumulated total pays out.
Free Spins need three scatters to start, handing out 12 spins plus two more for every additional scatter beyond the third. The Knight opens the round already holding 8x to 15x the stake and stays put for the whole bonus, defeating Monsters of equal or lesser value to add to that total. A separate multiplier applies to standard ways wins, starting at 1x and climbing by one step for every Monster the Knight defeats, though Monsters cleared during a Hold and Spin round that launches mid-feature (five or more landing at once) don't add to it. Landing three scatters during the round itself adds four extra spins, plus two per additional scatter.
A Power Play side bet, priced at eight times the base bet, guarantees at least 10,000 Megaways on every spin it's active for. Outside of that, the Hold and Spin round can be bought outright for 35x the stake, and Free Spins for 90x.
Big Time Gaming rates Monster Quest as high volatility, with a headline RTP of 96.49% alongside lower-paying configurations at 94.41%, 91.41% and 86.35% that operators may run instead. A spin costs as little as 0.10 or as much as 2.50, and the maximum win is capped at 99,900 times the bet.

Monster Quest is rated high volatility. High-volatility slots pay out less often, but wins tend to be bigger when they land — expect longer dry spells and larger swings to your balance.
The advertised maximum win for Monster Quest is 99,900x. Max wins are extremely rare by design — treat them as a ceiling, not an expectation.
