Jack Frost

Players seeking the best online slots will want to look closely at Rival Gaming’s Jack Frost.

Though the naming rights go to the lord of cold, this five-reel release is really more of a struggle between the forces of winter, personified by Jack Frost, and those of summer, in the form of Harold Heat.

Whichever season gamblers prefer, there’s much to look forward to in this feature-packed title:

- Flaming sticky wilds
- Drop Icons available during base play, essentially turning every win into a free chance for more
- The Jack Frost Ice Block Bonus
- Harold Heat Free Spins

Theme

For all the conflict between hot and cold found here, players begin with a fairly one-sided account, as base play is set in the depth of winter.

It’s a snowy winter wonderland behind the five reels!

Gaming symbols all have their hot and cold sides, respectively for base play and free spins: there are Christmas tree ornaments that become coconut cocktails, ice skates that become flip flops, ski goggles that become sunglasses, Christmas presents that become book bags, candy canes that become bananas, and fur-lined winter hats that become baseball caps. Groups of Jacks and Harolds also appear, offering a top payout of 500x for five-of-a-kind.

Wild symbols are available (becoming sticky during free spins), substituting for other symbols to form winning combinations. A lock and key combination is the gateway to the Bonus Round, where treasure chests are opened, revealing instant prizes.

This title’s most important symbols, though…

… are the single figures of Harold and Jack. The former acts as scatter, opening the way to free spins, while the latter opens the way to the Ice Block Bonus feature.

Our Take

The choice of favorite season may not be a simple one, but one thing is downright obvious…

… Jack Frost is positively packed with features!

Rival Gaming has outdone itself here. Visual design is also sophisticated here – overall, this is one of their finest releases yet.

One area for improvement would be RTP, which is still lower than we’d like.
