Features Black Hole by Merkur Gaming is a five-reel, five-line Cashpot slot with very high volatility. In the base game, player wins build a tower and increase the Cashpot, which is formed from the total tower values. The Cashpot can be taken in part or in full, while direct wins are paid only when the tower is complete.
The Black Hole symbol plays a central role in the mechanics, resetting both the Cashpot and the tower to zero. This creates a structured risk-based format in which each round can change the current position on the reels. The game is designed for players looking for a slot with a higher level of variance and a clear focus on accumulating value across spins.
A demo version is available here, allowing users to play for free and practice before playing for real money. The page provides a quick way to review the slot’s rules, Cashpot system, and reset feature before starting a live game session.
