Monster Quest online slot game
The Monster Quest slot’s premise is simple – a brave Knight wanders a Megaways grid, slaying monsters and stealing their cash values. This title from Big Time Gaming is built around a Hold and Spin mechanic where the Knight absorbs what it can reach. There is something refreshingly unique about it compared to other Megaways slots, and it is noticeably different in a way that may be both fascinating and frustrating, depending on how a session goes.
Monster Quest Slot Review: Our Hands-On Experience
We played Monster Quest Slot demo for 200 spins at a €1 stake on the desktop. The Hold and Spin triggered 3 times organically: first around spin 50 (21x), again at spin 130 (21x), and around spin 180 (21x). Around spin 140, 12 Free Spins triggered; a Hold and Spin fired inside the feature, and the combined result was 105.4x.
The base game felt busy but low-reward: wins came every 4-8 spins, most between 1x and 6x, with the balance bleeding at a steady medium pace. The biggest single result was 42.6x. Monster Quest suits patient, engaged players who can absorb a long wait for the feature to do something meaningful.

Monster Quest Theme and First Impressions
Big Time Gaming’s Monster Quest is a medieval fantasy-themed slot, where the background in the base game comprises stone castle walls, which later transform to a darker arena-style background in the Hold and Spin mode, surrounded by stone bull statues and torches. The change in background acts as an indicator that something important is about to happen, but it does not feel premium. Animations remain simplistic and do not have an extremely high-end feel to them.
While Castle of Terror 2 from the same studio grabs your attention with its atmospheric theme, Monster Quest is deliberately light.
The theme itself comes second after the gameplay, which is probably the right choice, taking into account how absorbing the Knight system can be.

How Monster Quest Plays – Base Game
The slot is played on six reels with 2-7 symbols per reel, producing up to 117,649 ways to win. Wins are paid left to right on adjacent symbols. The live ways count is displayed above the grid each spin.
There isn’t too much excitement in the base-game rhythm. Wins occur quite often, once every four to eight spins on average during our test run, yet they mostly range between 1x-3x the stake. Between features, the bankroll is decreasing steadily. Nothing accumulates without Free Spins or Hold and Spin.

Monster Quest Slot Bonus Features
Hold and Spin
The Hold and Spin feature gets triggered when there are six or more Bonus Symbols on the grid. Every grid position becomes a separate reel that spins and lands either a Monster or an empty spot. The Knight starts with three lives, and each spin without a new Monster or a monster being killed reduces the number of lives by one. Each slain Monster restores a life. The Knight slays any Monster with a value lower than or equal to its own. The round ends either when the Knight runs out of lives, kills the Dragon, or fills the grid with Monsters – the Knight’s accumulated value is then paid.
The emotional core of the game is here. The grids become filled increasingly with Monsters of high value: during our testing, individual positions showed values of 750x, 1,888x, and 3,888x – numbers which cannot be reached by the Knight, as its value is too low for that. There comes a certain critical point around 100x, where the Knight can start collecting mid-level Monsters and snowball. Before that, it was just collecting scraps between the prizes he couldn’t claim.
Free Spins
Should three or more Scatter symbols land on the reels, you get awarded 12 FS plus 2 for each additional Scatter. The Knight enters with a random value of 8-15 times the bet and remains on the screen. The Megaways Win Multiplier starts off at 1x and grows by 1x for each Monster killed. If five or more Monsters land simultaneously during Free Spins, a Hold and Spin triggers mid-feature. Landing 3 or more Scatters during Free Spins awards an extra 4 spins.
Bonus Buy
- Hold and Spin: 35x the stake
- Free Spins (12 spins): 90x the stake
What to Expect When Playing Monster Quest
Monster Quest is one of those slots where the fun really starts when entering bonus games, but before getting there, you get some work to do.
Win Potential and Volatility
The max win of 99,900x is achievable, but only if the Knight manages to accumulate the required Hold and Spin combo that wipes out the values of Monsters that individually can reach four and five figures. Typically, Hold and Spin wins range between 15x and 50x unless the Knight breaks past the 100x accumulation threshold. FS depend on the slot frequency and triggering an in-game Hold and Spin bonus. Four such triggers during our 200-spin session netted us a maximum of 105.4x.
Bet Range and Who It Suits
Bet range is €0.10-€2.50. Monster Quest suits players comfortable with a Megaways base game and a steadily declining balance between features, and are interested in a bonus where the result depends on how the Knight builds value. Casual players and high rollers should look elsewhere.
Mobile Performance
During our testing, Monster Quest performed well on mobile via browser. All controls scaled well to the smaller screen size. No app download is needed to play this Big Time Gaming title on a smartphone.
How Monster Quest Compares
| Game | Monster Quest | Castle of Terror 2 | Extra Chilli Megaways |
|---|---|---|---|
| Provider | Big Time Gaming | Big Time Gaming | Big Time Gaming |
| RTP | 96.49% | 96.48% | 96.19% |
| Volatility | High | High | High |
| Max Win | 99,900x | 20,160x | 20,000x |
| Buy Feature | Yes (35x / 90x) | Yes (100x / 300x) | Feature Drop (dynamic) |
| Min Bet | €0.10 | €0.10 | €0.20 |
| Key Feature | Knight collects + Hold and Spin | Modifier free spins | Unlimited multiplier + gamble wheel |
Monster Quest has the highest ceiling of the three. However, Castle of Terror 2 delivers more consistent free spins results, with 2-3 active modifiers and a climbing multiplier making most triggers feel meaningful. Extra Chilli Megaways focuses on the bonus game and the unlimited multiplier.
Verdict – Is Monster Quest Worth Playing?
Monster Quest from Big Time Gaming feels like a genuinely original mechanic, although it does not always justify its promise. The Knight feature brings an interesting plot aspect to the game, which is not found in many Megaways titles. However, organic Hold and Spin outcomes only become impressive once the multiplier hits 100x. Base game rounds do not bring anything exciting except for the features themselves. The €2.50 max bet caps nominal returns for high rollers.
This slot is worth trying if you want something different from a standard multiplier free spins slot. The 35x Hold and Spin buy makes it easy to test at low stakes. It will feel frustrating if you need the bonus to pay consistently.
