Monster Pop online slot game

Monster Pop is an exciting cluster wins slot game with 5x5 up to 13x13 reels and cluster wins with up to 1,000 symbols. Cascading reels, cloning features and wildcards will all help you form cluster wins, plus there is a free spins game that gives away up to 17 free goes.

Theme and Story Line

The Monster Pop video slot is set in a colourful world where bouncing and bubbly monsters party on the reels looking to create clusters with their own kind. In spite of their friendly nature, occasionally these monster get angry which works in your favour!

Graphics, Sounds, and Animations

BetSoft has long been known for its imaginative themes and astounding graphics. As such, you will be greeted with this developer’s traditional eye-popping visuals. The Monster Pop video slot cleverly incorporates colourful 3D symbols and a flurry of awesome animations within a cartoon-style design. The reels use a transparent effect and host a series of happy looking monsters bouncing on the reels while their curious eyes are continuously scanning their surroundings. In the background, a light theme tune plays out alongside what we would describe as ‘bubbly sound effects’.

When you begin, you will be spinning 5x5 reels with 25 symbols. As you continue to spin, the reel grid will extend up to a maximum of 13x13 which gives you a staggering 169 symbols. You will need the slot to link symbols into cluster wins on adjacent positions. The size of the cluster wins ranges between 4 and 1,000 depending on the reel format. 

You will be greeted by 8 friendly monsters helping you to create the cluster combinations. The highest paying monster is a multi-coloured star-shaped character. The lowest paying monster is the 3-eyed green one. Other monsters on the reels are red, light blue, purple, yellow, blue, and orange. Some have 2 eyes and others just one eye.

You can view all pays by pressing the ‘i’ button and selecting the paytable option – the payouts listed here are dynamic meaning they will auto-adjust the win amount when you modify you spin bet amount.

Bonuses and Free Spins

Monster Cloner: The game begins using 5x5 reels. Each time a purple monster cloner hits the reels the grid expands by adding rows and columns. When this happens, Oracle Eye wild symbols are added to the newly created positions giving you guaranteed cluster wins. 

Cascading Reels: Every winning cluster in the base game or during free spins will explode leaving empty spaces. The symbols above will fill the gaps left behind while more symbols will drop in from above the reels.

Oracle Eye Wilds: The electrified green Oracle Eye symbol is the wildcard and will substitute for any of the monster symbols.

Flaming Sphere Free Spins: Landing 3 or more flaming sphere symbols will award 7 free spins plus an additional free spin for each additional flaming sphere symbol up to a maximum of 17. Plus, each new flaming sphere symbol that lands on the reels during free spins will award a further free spin. If the grid expansion was already in action when frees spins were triggered, the grid will remain at this size until the feature ends.

Monster Fury: When a cascade results in no cluster pay combinations, the monsters occasionally get angry. They will randomly create a ‘cloner bomb’ launching ‘Monster Cloners’ all over the reels or they will shuffle around on the reels and latch onto identical monsters to form a win.

Bet sizes, RTP and Variance

BetSoft has kept Monster Pop simple when it comes to placing spin bets. Simply set your bet per spin between a minimum of 0.25 and a maximum of 25.00. The expected RTP is 94.67% which is below average for an online slot. Despite the low RTP, this is a medium variance slot game with regular small, medium, and large payouts. Most of your big wins will come courtesy of the free spins game – especially when triggered with an extended grid size. Those lucky enough to trigger free spins with a 13x13 grid are guaranteed to accumulate huge win multipliers.


Fans of cluster win video slots will be delighted with the Monster Pop online slot game release. BetSoft has yet again produced a spectacular cluster pays slot with cascading reels, plenty of features, and the chance to win a high max bet multiplier which is 2,271x. Monster Pop now joins slot titles such as Spinfinity Man (95.80%), Gemmed (96.46%), and Legend of Nile (95.63%) all recently added to BetSoft’s growing list of clusters pay online slot games which are now in high demand.
