About this Slot
Viking Upgrade is a mythology-themed slot by Phantom Interactive with an RTP of 96%, high volatility and a maximum win of 25,000x. The game uses a 6x5 grid with Cluster Pays and Cascading mechanics.
Three bonus symbols trigger the Bonus feature, which awards 10 free spins. During the Bonus round, high symbols double their multipliers while low symbols remain active throughout. Landing an additional Bonus symbol during the feature grants one extra spin.
Four bonus symbols trigger the Super Bonus feature, which awards 10 free spins with high symbol multipliers starting at a minimum of 16x.
Five bonus symbols trigger the Epic Bonus feature, awarding 10 free spins. During the Epic Bonus round, the two lowest-value symbols are routed out, and high symbol multipliers start at a minimum of 64x.
The Raid Spin is an enhanced single spin where only high symbols land. Multipliers on this spin range from 2x to 2048x and remain fixed for the entire spin.
Super Boost costs 2x the base bet and increases the chance of entering a bonus game. Hyper Boost costs 10x the base bet and provides a 20x increased chance of bonus entry.
The Super Bonus can be triggered directly by four symbols or purchased via the Hyper Boost option. The Epic Bonus can be triggered by five symbols or through a Mystery feature, which grants a 40% chance of the Super Bonus, a 10% chance of the Epic Bonus, and a 50% chance of a dead spin.
