Cascading symbols drop down in the grid to form winning combinations in this free slots demo game from PlaynGo Viking Runecraft Slot. Wins are achieved by getting 5 or more symbols in a connected cluster where they touch each other horizontally and/or vertically. Winning symbols are removed and new symbols drop in to fill up the grid. The game continues to cascade until no new winning combinations can be created. All wins during a game round contribute to increasing a charge meter of destruction. When the charge meter is fully charged and there are no more cascades, the charge effect is activated, triggering one of the following effects: Fury of Fenrir: Four diagonal lines of symbols are slashed on the grid. Two lines of symbols are removed, the other two lines of symbols are transformed to another symbol. Judgment of Jörmungandr: A large number of symbols are destroyed in an unbroken path from one edge point of the grid to another edge point of the grid. Along the path, a number of different symbol are transformed into another single symbol. Scorching of Surtr: Three symbols are set ablaze. The fire can spread to a random number of nearby symbols. All burning symbols are destroyed. In each cluster of burnt symbols, a core of new symbols is created. All symbols in each core consist of the same symbol. Lure of Loki: Two different symbols are selected. One symbol, and all its matching symbols are removed from the grid. The other symbol and all its matching symbols are transformed to another symbol Viking Runecraft. The game continues normally after the effect, allowing the charge meter to charge up for a second time. A single full charge following any of the above charge effects will trigger the Ragnarök feature which awards 1 free game round. Alternatively, when the charge meter of destruction is initially fully charged, it is possible to double charge it by winning on additional symbols. If you manage to fully double charge the charge meter before any effect is triggered, you trigger the Ragnarök feature directly. The Ragnarök feature can only be triggered once per game round. Whenever no more wins are achieved during the Ragnarök feature, one of the Charge of Destruction effects will play. When all Charge of Destruction effects have played once each and no more wins are awarded, the feature ends. During the Ragnarök feature, the Charge of Destruction is replaced with an End of the World bonus meter. Win on enough symbols during the entire Ragnarök feature and you will be richly rewarded with a total win multiplier! 20 symbols award an x2 multiplier. 40 symbols award an x3 multiplier. 60 symbols award an x5 multiplier. 80 symbols award an amazing x15 multiplier!
