Slot Monsters will be available at online casinos which carry slots from Parlay Games, and it’s a game that offers a very cute monster inspired design. It’s the type of design that we’ve been seeing a lot ever since the Monsters animation movie aired a couple of years back, and here it’s as good as ever.

You will have a setup with 5x3 reels, along with 20 active lines that combinations can form on. A top prize of about 5,000x the stake can be paid out by this game, though there is potential for even more with the right features. You can add a progressive jackpot to the list as well. The game relies on multipliers, expanding wilds, scatters and bonus games, to deliver impressive gameplay. RTP can be fairly high, even up to 98.10%, though the range is going to start very low.

Betting and Prizes

The coins which are used in the game have a value between $0.01 and $1. Since there are 20 lines, and each one gets up to 5 coins, bets will be as low as $0.20, but they can also be as high as $100 per spin.

When it comes to the payouts that you can get through Slot Monsters, there are two potential rewards to look forward to. I will mention the progressive jackpot first, since it’s a possibility, and about 1% of the RTP comes from this side. Otherwise, top prizes of up to 5,000x the stake seem possible when the right symbols form combinations on all lines. Add 5x multipliers as well, the highest ones available, and there is awesome potential in this game.

RTP varies considerably, between 71.90% and 98.10%, so I’m not quite sure where the average is.

Slot Monsters Slot Features

Consecutive winning combinations keep improving the wins, and that’s a big part of what makes this game fun. You get only the usual 1x multiplier for the first round, but the next ones will be boosted by 2x, 3x, 4x and then 5x multipliers. If a losing spin comes, the multiplier resets, but you keep taking advantage of the boost for as long as wins keep coming.

One of the Monsters you get on the reels will show up as a Wild, and it even has that logo on top, so you can easily tell which one he is. It’s an expanding wild, which is great for any slot, but it doesn’t act as a replacement for scatters.

The other feature symbol is a scatter with a Bonus logo on it, and some kind of box behind it. Land it scattered three to five times, and a bonus game is offered, with several picks that have to be made, in order to win cash prizes. There will be five monsters on the screen, and you have to pick three of them.

Theme & Design

The cute monster theme is not unique to this slot, but it always seems to result in a fun game, so I don’t mind seeing it in action again. Cartoon style graphics, the likes of which you’ve maybe seen in the original film as well, are going to be used for the major symbols. There are all sorts of monsters here, ranging from furry versions, to one-eyed or horned ones, some even slimy or with three eyes, horns and tail. A couple of other icons are also present, but there are mostly appropriate symbols on those reels.


Slot Monsters is not entirely original for Parlay Games, they have the same mechanics in other slots, but if I’d have to choose, the design and theme used here are probably the best ones around.
