Yak Yeti and Roll is the new winter themed slot game from Betsoft. Yak and Yeti are Himalayan icons, but this slot game also has symbols from the North Polar Region. The reels are set in a snowy landscape with the Yeti pulling the sled of the Eskimo. The background music has a vibrant festive jingle.

The symbols awarding line payouts are husky, reindeer, igloo, sled and mittens. The highest line payout is awarded by five husky symbols aligned from left to right on a payline. The payout is 7.50 times the total bet. The Eskimo is the scatter symbol. It also pays times the total bet when two or more appear anywhere on the reels. The highest payout of 12.50 times the total bet is for five scatter symbols. The Yeti is the wild symbol. It substitutes for all symbols except the scatter symbol. It appears only on reels 2, 3 and 4.

The Bonus Trail is the landmark feature of this slot game. A cascade follows every winning spin. The symbols in the winning combinations disappear and are replaced by fresh ones. If new winning combinations are formed then the cascades will continue. There are many video slots that incorporate this feature. But Betsoft takes this one step further. Each cascade advances the bonus trail. The trail at certain positions awards benefits. These are free spins, cascade multipliers, free spins multipliers and cash wins. For example, the 2nd cascade will award a 2x multiplier and the 7th cascade will award 8 free spins. The complete details are described in the payout table. Win multipliers are not applied to bonus credits. Cascade multipliers are applied to all subsequent wins. At the start of the next spin the bonus trail is reset to initial position.

The free spins are as such triggered through the bonus trail. But if you do not want to wait for this random occurrence then you can buy a free spins feature by paying a fee. The fee is 130 times the total bet that will determine the free spins payouts. You will be awarded 18 free spins at a payout multiplier of 4x.

Yak Yeti and Roll also has the standard Double Up feature. After any win the feature can be activated. You can gamble half or all of your winnings as many times as you wish. You have to predict the result of the coin toss. If you guess right then your staked amount will be doubled. The feature is not available in the free spins.
