Jack Frost

The online slot machine Jack Frost by Rival Gaming calls for you every time it snows outside. And even if it's not - come and check it out anyways! Although the lord of cold gets credit for the name, the conflict here is primarily between the powers of winter and summer, represented by Jack Frost and Harold Heat, respectively. So, try out this 5x3 game with a bonus round, up to 25 paylines, and a 94.98% RTP. Go into the free spins round for sticky wilds that repeatedly cause respins. Get even more details about core gameplay and special features in the Jack Frost slot review below!

Graphics Design

Each player starts with a pretty one-sided account because the base play is situated in the dead of winter, despite all the battles between hot and cold found here.  
For base play and free spins, the gaming symbols all have hot and cold counterparts: there are Christmas tree ornaments that transform into coconut cocktails, ice skates that transform into flip flops, ski goggles that transform into sunglasses, Christmas presents that transform into book bags, candy canes that transform into bananas, and fur-lined winter hats that transform into baseball caps. In addition, a peak payout of 500x is available for five of a type when groups of Jacks or Harolds appear.

Core Gameplay

Setting your bet on the Jack Frost slot game is the beginning of the fun. First, decide how many coins (1–10) and what value (1–10) you want to assign to each one (0.01 – 0.25). Before setting your total stake, which can range between 0.10 to 62.50, you must also decide how many paylines (10 to 25) you want to play on. 
When creating winning combos, wild symbols can be used instead of other symbols (becoming sticky during bonus spins). The entrance to the Bonus Round, when treasure chests are opened to reveal instant prizes, is a lock and key combination.  
But the two isolated characters, Harold and Jack, are the most significant symbols in this slot machine. While the latter unlocks the Ice Block Bonus feature, the former serves as a scatter and leads to free spins.

In-Game Extras

As for special features you get for various combinations with wild and scatter symbols, there are plenty of them. Here's what you can expect: 

  • when three or more Jack Frost Bonus symbols appear on the reels, the Ice Block Bonus round is activated.
  • players who melt ice chunks gain access to instant rewards or bonus spins.  
  • the free spins feature is started when three or more scatter symbols of Harold Heat appear.  
  • the game switches from winter to summer play!
  • Depending on the number of scatters that activated the bonus, 5, 10, or 20 free spins will be given. During the bonus, sticky wilds also appear on the reels. These symbols will hold their position while other reels re-spin whenever they contribute to a win.
  • Additional re-spins will result if extra sticky wilds arise.
