This slot machine based on Norse mythology can be played from 0.10 to 100 per spin, and it's available on desktop, tablet, and mobile. All of the standard playing card symbols are present, including the A, K, Q, J, and 10 lower-value royals, as well as tridents, pendants, treasure chests, kraken idols, and the kraken himself. The latter is by far the symbol with the highest value, as getting 2, 3, 4, or 5 of them in a combination will give you 1.5, 10, 50, or 500 times your original bet respectively.
To create a winning combination, you must line up at least two symbols (or three for the royals) consecutively from left to right across multiple reels. A gold Kraken emblem acts as a wild and scatter, substituting for other symbols to help you win; five of these anywhere on the reels will award you 500 times your wager.
When you get a winning combination that includes a Kraken emblem symbol, that symbol will expand on its own in Beat the Beast: Kraken's Lair thanks to the game's Expanding Win feature. This can increase the chances of getting high-paying symbols on the reels.
The Kraken emblem also serves as a scatter, and landing three, four, or five of them will award you with 2, 20, or 200 times your initial wager and launch the Bonus Game feature. Starting with 10 free spins, a Kraken emblem symbol will be randomly placed on any reel before each free spin, increasing your chances of triggering the Expanding Win feature. It's possible to get an additional 10 spins for free, for a total of 20, if you manage to retrigger the feature.
