About this Slot
Cauldron is an alchemy, fantasy, Halloween, horror and vampire-themed slot from Kishta Labs with an RTP of 96.6%, high volatility and a maximum win of 99,999x. The game uses 5 reels across 9 rows with ways to win.
Winning symbols pop and disappear, triggering reel expansion to a maximum of 9 rows. A wave pays after each pop. Win Both Ways means winning combinations count from left to right and right to left.
The Extension Boost buy option doubles the extension effect per spin. The Bonus buy option costs 200x the bet and grants entry to the Bonus tier. The Super buy option costs 500x the bet and grants entry to the Super tier.
Filling all reels during a wave triggers one of three bonus tiers. Bonus tier unlocks at 7 rows and plays 8 spins with a multiplier starting at x1, increasing by +1 after each winning wave. Super tier unlocks at 8 rows and plays 8 spins with a multiplier starting at x2, increasing by +2 after each winning wave. Hidden tier unlocks at 9 rows and plays 8 spins with a multiplier starting at x5, increasing by +5 after each winning wave. The board size remains fixed across all free spins in Bonus and Super tiers. Bonus tiers cannot retrigger; only Extra Spins symbols extend the feature by 1 to 3 spins, up to a maximum of 30 total spins.
Wild symbols substitute for base symbols but never pay alone. In base game and Hidden tier, wilds land on any reel. In Bonus and Super tiers, wilds land on limited reels. When a wild completes two winning combinations, the higher amount pays.
A Multiplier symbol raises the base game multiplier by +1 to +5 before each wave, starting from x1.
