Missions are a feature which is part of Yggdrasil’s in-game promo tool called Boost. It allows players to compete against each other, complete missions and win pretty big prizes. In one of them, participants had to complete three objectives: win 4 consecutive spins in Golden Fish Tank, trigger free spins in Vikings Go Wild, and collect 5 shards of any colour in the Holmes And The Stolen Stones. The player who managed to do all that with the fewest number of spins, won the main prize of €5,000.
