Monster Quest is an online slot from Big Time Gaming, the studio that created the Megaways mechanic, and it sends a lone knight into a cartoon fantasy kingdom overrun by beasts. The key art sets the tone straight away: a snarling green goblin, a blue scaled lizard-creature and a pink horned brute burst out from behind a chunky golden title, while sunlit meadows and stone castle towers stretch into the distance. The style is bright, rounded and full of character, closer to an animated adventure film than a grim medieval epic, and the soundtrack follows suit with a heroic, playful orchestral score.
The game is built on 6 reels using Megaways, with each reel showing between two and seven symbols on every spin, giving up to 117,649 ways to win. That shifting reel height means no two spins look quite the same, and it keeps the base game moving with plenty of small connections. On top of that sit a Hold and Spin battle round, a free spins feature with a growing win multiplier, an optional Power Play mode and two bonus buys. Each of these is described in detail later, but together they make Monster Quest one of the more feature-rich titles in the BTG catalogue.
The slot is best suited to players who already enjoy Megaways games and want something with more storytelling than the usual symbol cascade. The knight-versus-monster battle gives the bonus rounds a clear goal, which makes them easy to follow and genuinely tense. If a light-hearted fantasy theme combined with serious win potential sounds appealing, the sections below explain how the quest actually plays out.
Every spin reshapes the 6 reels, with between two and seven symbols per reel and up to 117,649 ways to connect matching symbols from left to right. The base game keeps a steady flow of small wins, but the real objective is collecting Bonus symbols. The Knight, the Dragon and several Monsters can all land as Bonus symbols, and six or more of them anywhere on the grid trigger the Hold and Spin feature.
Hold and Spin plays out as a battle. Every position becomes its own mini reel, and new Monsters can appear as the round continues. The Knight slays any Monster whose value is equal to or lower than his own and adds that value to his total, growing stronger with each victory. He starts with three lives; a spin without a new Monster appearing or being slain costs one, while each kill restores a life up to the maximum. The round ends when the Knight falls or defeats the Dragon, and his final value is paid out.
Three or more Scatters award 12 free spins, plus two for each extra Scatter. The Knight joins with a random starting value between 8x and 15x the stake and stays on screen, slaying weaker Monsters as they appear. A Megaways Win Multiplier starts at 1x and rises by one for each Monster slain. Five or more Monsters at once launch Hold and Spin inside the free spins, and three or more Scatters add four more spins. Power Play costs 8x the stake and guarantees at least 10,000 Megaways, while the Bonus Buy offers Hold and Spin for 35x or free spins for 90x.
The standard RTP of 96.49% puts Monster Quest in line with the market average, and a slightly higher 96.58% configuration also exists. Some casinos run lower versions, so it is worth checking the game information screen before playing. In any case, the long-term return is competitive, but it is not what defines the experience here.
What defines it is high volatility. Megaways games naturally produce many small wins, yet the large payouts in Monster Quest depend on the knight's battles going well, and those battles are unpredictable by design. A Hold and Spin round can end early if the knight runs out of lives, or it can snowball as each victory restores a life and raises his value. Free spins work in a similar way, with the multiplier growing only when monsters fall. That creates sessions with long quiet stretches and occasional explosive rounds.
The maximum win of 99,900x the stake is an extraordinary ceiling and only realistic when the knight slays a long chain of monsters, ideally including the dragon, while the free spins multiplier is already high. There is no jackpot, so the battle mechanics carry the full upside. The bonus buys and Power Play let players shape their risk, but they also raise the cost per spin considerably. Overall, this is a slot for patient players who accept heavy swings in exchange for some of the biggest potential wins BTG has offered.
Based on reviews
Bought the free spins at 90x and the knight went on a rampage, multiplier reached x11 before a 7,000-way spin connected. Finished on just over 1,600x. Very high volatility, but this is why you play it.
The goblin and the pink horned monster are hilarious, the art is so cheerful. It plays well on my phone too. The base game can feel slow, but the shifting reels keep it from getting boring.
Hold and Spin is the best part for me. Watching the knight drop to one life and then slay a monster to get back to three is proper edge-of-the-seat stuff. Killed the dragon once for a 420x round.
Checked the info screen and my casino had the 96.49% version, which is fine. Over 600 spins the dead spins were long, but the feature rate felt fair for a BTG Megaways game.
Power Play at 8x is pricey but the 10,000 Megaways minimum makes the base game hit much more often. Triggered Hold and Spin naturally twice in one session with it on.
