On this page, we’re going to tell you all about our experience and how the game works.

This slot machine is a work of Mancala Gaming, and it was launched in 2020. For those of you that are unfamiliar, Mancala Gaming is a Prague-based online casino game development firm, and it was established in 2019. Mancala is mostly fixated on making some great slots and also dice games. They offer around 90 games in their portfolio right now, and Monster Thrives is certainly one of their best works to date. In 2024, Mancala Gaming even won the “Best Slot Game Provider of the Year” award at the Sigma African Awards, and this is certainly a feather in their cap, thanks mainly to slot machines like Monster Thieves.
When you play this slot and others from Mancala, you will get a first-hand understanding of why they were awarded. They are known for partnering with other quality providers like Parimatch, SoftSwiss, and BetConstruct in order to collaborate and make epic games. Monster Thieves has 5 reels, 4 rows, and a whopping 1024 ways to win. The features of the game include a pick bonus, multipliers, wilds, and 1024 paylines!
Quirky Theme
The quirky theme is nothing like we’ve seen before. The online slot market is inundated with slots focused on themes like Las Vegas and Ancient Egypt, and so it is always a pleasant surprise to see some unique and authentic themes like what’s been implemented with this game. The reels are set in what looks like a cozy little attic room with slanted windows and plenty of moonlight flooding into the room. The monsters are hiding somewhere in this room, and it’s almost like a fun little puzzle you have to solve to find their hiding spots. As you spin the reels, if you pay attention to the backdrop, you’ll see them popping out just for a fraction of a second from various nooks and corners of the room, and just spotting these quirky little monsters is like a fun little side quest by itself.
1024 ways to win
Most slot games will have something like 20–25 paylines. Paylines are basically the number of combinations of symbols on the reels that, if formed during your spins, will result in you winning money. This game has a staggering 1024 ways to win, and this makes the game immediately attractive to most players, and they quickly click on the game because of this reason, and it seems to really promote the popularity of the game.
Wide Betting Range
The betting range is huge here. You can bet just 10 coins or up to a mind-boggling 5000 coins per spin. So, the game is great for anyone with any budget. If you are on a tight budget, play with just 10 coins, and you can still play for extended periods of time without spending much money. But if you have deep pockets and want a game where you can really go big with every spin, then you’ll be hard pressed to find any other game allowing you to wager a whopping 5000 coins per spin.
Bonus Pick Game
The bonus pick game is triggered when you land three bonus symbols anywhere on the reels on the same spin. When this happens, you're taken to a new screen where you see a selection of boxes. You get to pick from these boxes, and each one contains instant cash prizes or up to 30 free spins.
The instant cash prizes can vary in amount, and they will immediately skyrocket your winnings. If you're lucky, you may pick a box that contains a high cash prize, and this could significantly increase your balance within seconds!
Free spins in Monster Thieves come in two forms: the in-game free spins you get from the bonus pick game and the external free spins you may receive as a bonus from an online casino or a promotion that an affiliate site and a casino have collaboratively come up with.
The in-game free spins are awarded when you trigger the bonus pick and then happen to select the boxes that contain the free spins. These spins are played within the game, and any winnings you get are added to your balance. Since these free spins are part of the game, there is no wagering requirement tied to them, and so you can withdraw the winning as though it were your own money. No need to wager it a certain number of times or anything.
External free spins are the ones you get from the casino as a promotion, like the no deposit free spins we talked about at the beginnings. When you use these spins on Monster Thieves, any winnings you earn are subject to the casino's wagering requirements. This means you need to wager the winnings a certain number of times before you can withdraw them.
For example, suppose you receive 20 free spins and win $10 from using them. If the wagering requirement is 30x, you need to wager $10 x 30 = $300 before you can withdraw the $10 winnings. For some people, this may be doable, but for others, it could be biting more than they can chew. So, before you claim any bonus, be it free spins or any other bonus, always check the bonus terms and conditions and see how much the wagering requirements are, how long you get to fulfill them, and whether you will be able to do so without having to burn a hole through your pockets.
From the example provided, it should be clear and obvious that the lower the wagering requirements are, the better it is for the player because it is easier to complete and withdraw the bonus funds. So, a wagering requirement of 20x is better than one of 50x, provided all other factors of the bonus are the same for both offers. Also, there are going to be time limits within which you need to fulfil the bonus wagering requirements, and you can’t take however long you want. So, make sure the time provided is sufficient for you to wager that much money at the casino.
If the requirements are too high or/and the time frame is too limited, then let it pass and don’t claim it. Don’t worry, the online casino world is filled with bonuses, and you’ll surely come across another one with better terms and conditions where you can actually turn a nice little profit.
