About this Slot
Sinking Treasures is a mythology, horror and gems themed slot from Billion Studios with an RTP of 96.7%, medium volatility and a maximum win of 10,000x. The game features a 5x5 grid with cluster pays mechanics.
Cascading symbols drop down the reels after each winning cluster, creating the potential for consecutive wins on a single spin.
A Symbol Counter tracks collected symbols across spins and reaches milestones at 7, 14, 26 and 42. Reaching the 42-symbol milestone triggers the Other World Free Round.
Double Wild, available as a 5x bet purchase, drops two randomly placed wild symbols on each spin.
The NORMAL BONUS costs 100x the bet and activates a Bonus Wheel that awards between 3 and 9 free spins. The wheel also determines the size of the Shoggoth MEGAWILD for that bonus round.
Super Bonus costs 200x the bet and also triggers the Bonus Wheel feature.
MEGAWILD Spin is available for 500x the bet. During this mode, a wild symbol lands and slides down one square with each respin, while any standard wilds that land remain active throughout.
In the game, Cthulhu WILD replaces other symbols and doubles all wins formed by connected clusters it touches. Shoggoth MEGAWILD lands as a 2x2, 3x3, 4x4 or 5x5 block and acts as a wild for any clusters it touches.
Two additional modifiers appear during play: Sweep clears one full line vertically or horizontally, while Vanish removes all copies of a single symbol from the grid.
