The Underwater World slot machine is characterized by an average theoretical return. Which means that the player must realize that he is expected to both successful and losing series of bets. At high volatility, the slot pays rarely, but allows you to rip off a good score.
It is up to him to decide whether it makes sense to test one of the popular strategies of the game in practice. Whether a player chooses the Martingale strategy, the d'Alambert system, or the Parlay meteodic, none of them is a guarantee of increased winnings, but only allows to control the bankroll and make the gameplay more varied.
