What are underwater progressive slots?

These are games that provide players with a chance to win a huge jackpot. Progressive slots have at least one additional jackpot aside from the prizes offered on the paytable for each game. It will get progressively larger the more bets are placed on the game, hence the name.

Some slots might offer more than one progressive jackpot. If this is the case, you will notice they all get progressively larger, but even the smallest ones can be cool to win if you get lucky. Some will be triggered at random, while others will be won if you manage to get through to a special bonus feature to determine which jackpot you could win.

Exploring the many underwater bonus slots online today

Underwater-themed games often include bonus features to make the games even more exciting to play. The most common bonus involves winning some free games, although these often include other special features that elevate them above the normal spins you would make on that game. For example, you might get expanding wilds rather than regular wilds. You might get tripled prizes instead of regular ones.

Other slots feature second screen bonuses. These occur in a different setting, so for example you might see an underwater scene with buried treasure in several locations. Being asked to explore your underwater setting is cool, because you never know what you will find there!
