What are the base-game wild features?

  • Wild Respins: four or more wilds start a respin. The wilds stay and move to random spots, and each new wild adds another respin. It ends when a respin brings no new wild.
  • Shifting Stacked Wilds: stacked wilds on reels 2, 3 and 4 shift to cover the whole reel, adding +1 to the win multiplier for every position they move.
  • Kraken guaranteed win: on some losing spins the Kraken rearranges the symbols to give a win of 20x or more. It can also hand you the scatters for the bonus.

How do the free spins work?

Three or more scatters start a pick game with 16 boxes. Each pick offers a number of spins and a starting multiplier, which you can accept or swap for another pick.

ScattersFree spinsStarting multiplier
34 to 15Up to x6
45 to 20Up to x10
56 to 20Up to x10

During the round, wilds become sticky and move to a new spot each spin. Golden wilds add +1 to the multiplier. The free spins cannot be retriggered.
