Yggdrasil turns up the power in 777 Volt Gigablox

Symbols can grow up to 6×6 in size in this six-reel slot thanks to Yggdrasil’s leading Game Engagement Mechanic (GEM) GigaBlox. Players can also win a maximum of 5,000x their stake via free spins with extra features and hugely lucrative diamond symbols.

Landing five or more scatter symbols anywhere on the reels will trigger a free spins bonus, during which players can pick extra features which can seriously boost bonus gameplay.

Those additional possibilities to win include wild high which sees high-paying symbols transformed into a wild, 2x win multipliers, expanded reels, extra wilds, additional free spins and high stacks which sees one high-paying symbol stacked on the reels.

Before the bonus begins players can opt to gamble to unlock up to eight extra features by playing a pick-and-click mini-game. Making the wrong choice immediately ends the free spins session.

Diamond symbols can land on the fifth reel at any time awarding an instant cash prize or free spins, even if the precious gem is only partially visible. The bigger the diamond the better the reward.

Tomasz Kowalik, head of games production at Yggdrasil, said: “There’s something special about the GigaBlox GEM. Players quickly fell in love with the mechanic as soon as we introduced it to our games and our portfolio has been boosted by it ever since.

“We are confident that 777 Volt GigaBlox will be another huge hit for Yggdrasil, in part thanks to its epic GigaBlox gameplay and game enhancing free spins features that have so much to offer.”
