Jack & the Mystery Monsters Slot Review

How to play

The Jack and the Mystery Monsters video slot features 15 fixed paylines and very simple gameplay. You spin symbols on five colorful reels and three rows, and if you’re lucky, you land winning combinations and cash out. The game is straightforward, whether you’re familiar with slots or not.

Start by selecting your total bet. All the symbol payouts are multiplied by the total bet and so there’s no fuss about adjusting your bet per line or number of paylines. You can stake between €0.04 and €100 for each round, and since this range is pretty wide, players with high and low budgets can play the slot.

After choosing your bet, click on the spin button so that the reels will turn. You can go for autoplay if you want the reels to turn automatically without your supervision. A win only counts when it’s with matching symbols, on any of the paylines, from left to right, and on adjacent reels.

Symbols and payouts

There are a variety of symbols on the Jack and the Mystery Monsters slot reels, some unlocking bonuses and the others giving players impressive payouts. You can look out for the free spins symbol, bonus symbol which is Jack, wild, and the backpack symbol acting as the scatter.

The wild will reward you with 1,000x, 100x, 10x, and 1x your total bet for landing five, four, three, and two symbols on any of the paylines. Then, the scatter pays anyway with 50x, 20x, and 5x your bet when you get five, four, and three in a combination.

Next are the standard symbols. The red monster offers 50x, 10x, 5x, and 0.5x your total bet for five, four, three, and two symbols on any of the paylines.

Then, we have the purple and blue monsters with the same rewards of 15x, 5x, 1x and 0.25x your bet, also for landing five, four, three, and two symbols of a kind in a win.

The green monster and A symbol give the same payouts of 10x, 5x, and 0.5x your total bet for hitting five, four, and three symbols across the reels.

Finally, we have K, Q, J, and 10, which each offer identical rewards. They will all pay out 5x, 1x, and 0.25x your bet for five, four, and three of a kind.

Best Jack and the Mystery Monsters bonus features

The Jack and the Mystery Monsters bonus features are plentiful, so you can say this slot is filled to the brim with rewards.

This starts from the wild symbol which can stand-in for all the symbols on the reels to form a winning combination, except for the scatter, free spins symbol, and the bonus game. Not only does the wild offer up to 1,000x your bet for five on a payline, but comes with a 2x multiplier on any win it creates.

The slot has a scatter that offers payouts but does not unlock any bonuses. To unlock the Jack and the Mystery Monsters free spins round, you need to land the symbols with FREE SPINS written on them. If you land three on the first, second, and third reels with the same spin, you get 10 free spins.

The free spins feature comes with an increasing multiplier bonus. It starts at 1x and increases by one each time a wild lands on the reels. It can go all the way up to 21x your wins during free spins. The wild can stand in for all symbols here except the scatter. The free spins cannot be retriggered.

Then, we have the Jack and the Mystery Monsters bonus game that is activated with three bonus symbols landing on the third, fourth, and fifth reels at the same time. It has two locations. In the first location, you pick one out of five hidden prizes. Then in the second, you pick one out of two hidden multipliers. The multipliers will multiply the prize in the first location.

RTP and volatility

The Jack and the Mystery Monsters RTP is 96.20% (or between 88.35% and 98%, according to Synot). Combine this with medium volatility and you get decent rewards every now and then.
