Cool Wolf slot from Microgaming

Cool Wolf slot from MicrogamingIf you like the allure of youth, shapeshifting into a wolf, and rock ’n roll, this 2014 Microgaming slot is right for you. Cool Wolf slot machine revolves around a teenager changing into something vicious, unpredictable, and wild. Here you will have a large spectrum of transitions: from the dramatic changes - the werewolf transformation, to the usual behavioural switch of a teenager - playful and erratic - with his sunglasses, electric guitar, and ready to rock.

Of course, with his bad boy look, this dude is attracting ladies attention, and they love to take a ride in his powerful supercar. The Rolling Reels keep the action going, and with stacked Wilds, Free Spins, and the uplifting soundtrack in the background, there’s never a dull moment. We advise you to try the Thunderstruck Wild Lightning slot by Microgaming for free.

It all takes place on a 5x3 grid, crossed with 243 win lines, medium volatility,  a generous RTP of 96.47%; this fast-paced slot is certainly to howl for. Try it for free in the DEMO version on our page. No registration is required.

Personal testers’ opinion

We do like to feel young, and therefore we did enjoy testing this slot. There are just a few little downsides. Statistically, you can expect the Free Spins bonus round only every 169th spin (0.59%), i.e. prepare yourself for the waiting. Around 26% of the prize pool is reserved for the payment of wins during the Free Spins. Hitting any win is easier because the hit probability is approximately 32-33 spins out of 100. According to our wagering ranking meter, the Cool Wolf slot machine is not suitable for fulfilling the requirements - it registered here only 4.16 (out of 10) points.
