Sienna Steele is a heist-themed slot developed by High Limit Studio, set in a luxurious bank vault environment. The game features a 5×3 reel layout with 25 fixed paylines, offering players a medium volatility experience with an RTP of 96.01%.
The slot's symbols are thematically designed, featuring low-paying card suits (Diamonds, Clubs, Hearts, and Spades) and high-value items associated with wealth and burglary. Premium symbols include Gold Coins, Cash, Diamonds, and Safes, with the Safe being the highest-paying symbol, offering 8x the bet for five across a payline.
Wild symbols appear on reels 2 to 5, substituting for all regular pay symbols to help form winning combinations. Scatter symbols, represented by the Golden Safe Door, appear on reels 2, 3, and 4, and are key to triggering the Free Spins feature.
