Symbols and Winning Combinations of Jack and the Mystery Monsters Slot

Winning CombinationsOnce again, SYNOT Games manage to deliver a skillfully rendered slot that compels the attention with masterful animations and equally fitting sound effects. Five transparent reels spin against a backdrop that features a magical forest where different mysterious creatures dwell. You can mingle with fireflies and the four quirky monsters that award the largest prizes in Jack and the Mystery Monsters.

The higher payer in the paytable is the reddish monster styled to resemble a tree stub. Two of those result in a payout of half your bet, while five matches can enrich you with 50x your total stake per spin. Next in line are the quicky-looking purple and blue monsters, each of which awards between 0.25x and 15x your total wager for two to five matches. The next high payer is the green critter, yielding prizes between 0.25x and 10x your overall bet.

There are five lower payers featured in the game and all five contain the initials of the familiar playing cards (10, J, Q, K, and A). All of them yield payouts of 0.25x to 5x your total bet for three to five alike symbols. To form a paying combination, the symbols must hit one of the 15 fixed win lines, starting from the leftmost to the rightmost reel.

Bonus Features of Jack and the Mystery Monsters Slot

Bonus imageJack and the Mystery Monsters includes all the extra features one can think of. To begin with, there is the usual wild symbol that can stand in for all regular icons, allowing you to create more paying combos. The only exception to this rule is the other special icon that unlocks the bonus game – the green wild cannot replace it.

Apart from substituting, the free wild holds the key to unlocking a round of ten free spins. The wild makes an appearance on the second and fourth reels only. This triggers the free spins feature. Each occurring wild within its duration boosts the free spins multiplier by one, up to a maximum of 21x.

The scatter with Jack’s backpack produces payouts ranging from 5x to 50x your bet whenever the alike symbols land on neighboring reels. Jack himself acts as a bonus symbol, unlocking the bonus game whenever it hits the third, fourth, and fifth reels at the same time. You can win anywhere between 10x and 200x the total bet during this special feature.

Jack and the Mystery Monsters features a bonus game consisting of two stages. During the first one, you must select one out of five mystery items to reveal the prize hidden below. The second stage requires you to pick one of two items to get a multiplier that boosts the monetary prize you have won during the first stage.

Finally, the slot features several interesting functionalities that aim to further improve the quality of your gameplay. You can activate the Autoplay feature to play up to a thousand uninterrupted spins. There is also a Gamble option where you risk your profits from the last spin by playing a guessing game.


The first thing that strikes you the moment you open Jack and the Mystery Monsters is the superb quality of its visuals and animations. The cartoon-like icons with the monsters are original and cute. The special features further boost the winning potential of this magic-themed slot. All in all, SYNOT Games have created a truly enchanting game so the least you should do is give it a try.
