Expert Tips for Winning at Dolphin Reef

Maximize Your Paylines

Dolphin Reef allows you to choose your active paylines. To ensure you don't miss out on winning combinations, it is recommended to keep all 20 lines active even with a smaller bet per line.

Watch Reels 2 and 4

The Dolphin Wild only appears on the second and fourth reels. When they appear simultaneously, they expand to cover the whole reel and trigger 5 re-spins. This is the key to the game's biggest payouts.

Bankroll Management

Given the medium-high volatility, it's wise to set a budget before starting. Adjust your bet size to allow for at least 100 spins to increase your chances of hitting the bonus re-spin round.

Scatter Pays Anywhere

The Treasure Chest is the scatter symbol. Unlike other symbols, it doesn't need to be on a payline to win. Landing three or more anywhere on the reels provides an instant multiplier to your total bet.
