Playtech is taking players on an epic adventure based on Norse mythology in the fourth instalment of the developer's series of progressive video slots. All games forming this series are interconnected, which means that Tokens collected while playing can be later used to active in-game features in any of the available Kingdoms Rise slots. Playable from $0.10, this December 2019 release comes with 3 progressive jackpots on offer, along with a myriad of other rewarding features, such as Hammer Respins, and multipliers, while the Kingdom Rise Shop enables players to buy another potentially lucrative feature called the Barbarian and Valkyrie Respins.

The game is a part of a much bigger fantasy world, taking us to an icy kingdom. Just like the previous 3 Kingdoms Rise releases, this one also boasts stunning visuals that further add to the overall excitement. The reels are set against a wall of ice, with the reel set consisting of 5 reels and 3 rows, and a total of 25 fixed paylines. Playtech's game awards payouts for winning combinations of 3 or more symbols, paying from left to right. When it comes to betting options, players can bet as low as $0.10, while the maximum stake can go all the way up to $2,000 per spin.

Kingdoms Rise: Reign of Ice is a beautifully-designed game, just like the other slot from this series. On the reels, you'll encounter 4 brightly-coloured gemstones, axes, maces and crossed swords. There are 2 icons featuring character symbols – the Ice Valkyrie and the Ice Barbarian. The latter is the game's top-paying symbol, awarding a prize worth 12 times the triggering bet for 5 of a kind across a payline. The Wild symbol can substitute for all other symbols, except for other Wild present in this game.

Regular Wild will appear only on reels 3, 4, and 5, helping punters form additional winning combinations, leading to bigger prizes. However, regular Wild will not be able to stand in for Hammer Wild, which will appear only on reel 2, triggering Hammer Respins in the process.

Once the Hammer Respins feature is activated, all Wilds will freeze in their positions, and the reels will respin until a Wild finds it place on reel 2, with the Hammer symbol dropping down on the reels. This can be a very lucrative move, as the Hammer can boost a winning combination by up to 5 times. The respin feature will come to an end once all Hammers drop from the top.

Be sure to collect Tokens, which will appear during the game as part of other symbol. They can be used to purchase features in the Kingdoms Rise Shop. You can buy a feature not only from the Reign of Ice, but from other Kingdoms Rise games as well.

The randomly-activated Kingdoms Rise Jackpot feature enables players to claim 1 of the available jackpot. As its name suggests, the Daily Strike Jackpot is awarded on a daily basis, Power Strike Jackpot is paid out when it reaches a certain size, while the aptly named Epic Jackpot can award staggering awards! Apart from the progressive jackpots, you can claim prizes going up to 300x the stake. Add a 5x multiplier from the Hammer Respins, and the payout increase to 1,500x the wager on each of the respins!
