Dolphin's Pearl Deluxe - Online Slot Machine
Dolphin’s Pearl™ deluxe is an exciting 10-line, 5-reel game. With brand new high resolution 3D graphics in sub-aqua style and entrancing new sound it will thrill old fans and new players alike!
Dolphin substitutes for all symbols except scatters and doubles when substituting. 3, 4 or 5 scattered Pearls trigger 15 free games. Free games’ wins are multiplied by 3. An extra scatter symbol is added to the reels during the free spins, so that it's easier to increase the free spin rounds.
Moreover, a 5 of a kind combination of the Scatter symbol pays 500x the stake, while it pays a nice 1'500x the stake during the free spins.
All winnings made on this slot machine can be gambled in a red/black card game at the end of a game round. This double up game has a real 50/50 chance, so there's no house edge on this bet.
