You must pick whether you wish to use the Super Stake betting option before you play, or before you begin a new spin. This will increase your wager for each spin, but you will gain access to a wild feature that will occasionally activate on spins that would otherwise result in a loss.
The game offers 243 different ways to win and a both-way paying structure. The range of wagers is 0.25 to 125.00. The paytable lists prizes, and the payouts vary depending on the stake level you select.
If you want to activate the Super Stake ante bet option, you must do so upfront or at the very least in between spins. You will pay twice as much per spin, but you'll gain access to a randomly activated wild feature on the infrequent game in which you don't win. Every time it occurs, 2 to 6 wilds are added at random on reels 1 and 5, so take that into account.
On the first and fifth reels, the two wandering wild Viking symbols appear, and with each respin, they go to the opposite side. When there are no more walking wilds on the reels, the feature stops. You are given a free respin for each step the wilds take. You enter the Bonus Round if there are two adjacent walking wilds on the same row.
You get 10 free spins when two Viking warriors walking wilds collide on the same row. Additionally, for every additional pair of Viking wilds that meet on the reels, you receive an additional +4 spins. In the bonus round, you still receive +4 extra wilds, but now walking wilds can appear on all 5 reels rather than just reels 1 and 5.
The optional gamble function is activated each time you hit a winning combination. It's a fairly common double-or-nothing card game.
