About this Slot
Soul Siphon from 10000x is a mythology, fantasy, horror and medieval-themed slot with six reels, five rows and 15,625 Bet Ways. The game has an RTP of 96.5%, high volatility and a maximum win of 10,000x.
The game uses cascading wins, where winning combinations clear and new symbols fall to fill empty spaces. Cascades continue until the board settles with no further winning combinations.
Soul Wells begin with a x2 multiplier and double with each win, up to a maximum of x128. When multiple Soul Wells land on the same symbol, their multipliers combine together.
Free Spins trigger when three to six Free Spins symbols appear, awarding between five and twelve free spins. Multipliers earned during the base game persist through the bonus and continue to double during free spins.
Soul Bomb detonates a 3x3 area of the grid and doubles all Soul Well multipliers present. Soul Converter transforms a 3x3 area into a single matching symbol, but becomes inactive whenever Soul Bomb is present on the board.
Lich's Blessing converts regular symbols in a 3x3 area into Wilds, with a minimum of one Wild guaranteed. Cursed Crown drops a locked Wild onto the grid that remains in place through all subsequent cascades. Reaper's Decree converts an entire horizontal row into matching symbols.
Bonus buy options are available at Ante (1.5x bet), Super Ante (3x bet), Soul Harvest (100x bet), MYSTERY HARVEST (128x bet), GRAND HARVEST (150x bet) and REAPER'S HARVEST (200x bet).
