Cartoon critters take centre stage in Monster Mash, a 5reel, 243 ways to win slot from Odobo. The chief reason to give this creature themed slot a spin is the Free Spins feature that awards between 8 and 20 free spins complete with a multiplier that can range from anywhere between 2x and 10x. Play from 10p to £20 per spin. Monster Mash uses the 243 ways to win game engine rather than traditional paylines – make a winning formation by landing the same symbol on adjacent reels.

Visually, Odobo has kept things simple in Monster Mash – set against a simple sky and trees backdrop (imagine the Teletubbies without the sun!), the reels include a motley assortment of cartoon-style creatures. Even the playing card symbols get a ghoulish makeover. The buck toothed, four eyed blue beast is the top payer, offering 100 coins for a 5 symbol combo.

The Big Mouth symbol is the wild – appearing only on reels 1, 2, 3 and 4, it substitutes for every other symbol apart from the scatter (the Big Eye). Landing 3 scatters anywhere on the reels won’t get you a payout but it will trigger the Free Spins feature.

Before starting, you’ll be given the chance to build a monster by choosing a selection of body parts – keep picking to build your creation. Each part will randomly give you a number of free spins or a multiplier value. You can do this automatically if you prefer.

The spins and multipliers will be totted up and the free spins will play out – you’ll end up with between 8 and 20 free spins and a multiplier of anywhere between 2x and 10x. Land 3 or more scatters during the feature and you’ll be awarded the same number of free spins again.

It may not be overstocked in the features department but the innovative visuals and animations make Monster Mash a very easy play, especially for casual gamers. The variance is on the low side of medium but some bigger wins are possible if you’re lucky enough to build a monster that matches a decent number of free spins with a high value multiplier.

These aliens aren’t especially earth shaking but they combine to entertaining effect, making Monster Mash worth a look, especially for smaller stakes or casual players. If monsters are your thing, So Many Monsters by Microgaming is an option but I’d rather play other Odobo slot games like the brilliant Akaneiro.
