Slingo Information
Best Strategy
The best strategy dictates that the selection for positions of Wilds and Super Wilds is always in the position that will move the player closer to completing a Slingo.
Where multiple positions with the same criteria are available, the preference is given to positions which are included in the most Slingos (win lines). Where this is not applicable, a random choice is made.
For example the central square would be given preference since it is included in a horizontal, vertical and two diagonal lines.
Rules
All symbols occur on all reels.
Extra spins are available after each game.
Based on best strategy the standard game has a theoretical RTP of 94.02%.
