Yggdrasil, the world's leading publisher of online gaming content, has launched Games Lab's Towering Pays Valhalla, through its partner YG Masters, ReelPlay.
Ascend into the majestic halls of the Viking afterlife in this innovative, multi-configuration slot, which progresses from 15 to 65 active paylines using Games Lab's exclusive Towering Pays mechanic.
Spins appearing on reels 1, 2 and 3 trigger a row expansion, and players are offered a bonus feature if they repeat this behaviour when progressing through the 5×8 board. They will then have the choice to take the feature or reject it for another offer later.
With four separate free spins modes for the bonus game - Valkyrie, Loki, Thor and Odin - players have plenty of options for winning big. In the most lucrative mode, Odin Free Spins, spins can appear on all reels, offering a huge winning potential.
In some jurisdictions, free spins are also available for purchase, with players able to select their purchase level to increase their chances of triggering the optimum bonus mode.
Stuart McCarthy, Head of Product and Programmes at Yggdrasil, said: "Towering Pays Valhalla is a brand new feature to our YG Masters programme with an iconic theme enjoyed by slot players around the world. The YG Masters programme has been designed to bring innovation and excitement to players in studios around the world, and we are delighted to be able to launch this new hit."
David Johnson, CEO of ReelPlay, said: "We are delighted to help bring Games Lab's latest Towering Pays game to market with our partners at Yggdrasil. Valhalla is a game that grows with every turn thanks to its expanding reel matrix and multiple features. It builds on Games Lab's recent successful launches via YG Masters, such as Royal Dragon Infinity Reels."
