Dolphin Reef Online Slot Symbols

Dolphin Reef themed symbols include sea horses; clown fish; sea turtles; starfish and of dolphins as well as a treasure chest. The lower valued symbols include the standard playing card icons nine; ten; jack; queen; king and ace. These symbols award anything from 5 times the stake up to 250 times the stake. The aquatic themed symbols award various amounts for three to five symbols landing consecutively on an active pay line. The biggest pay out is up to 5 000 times the stake which is paid out for five of the clown fish symbols landing on an active pay line.

The Dolphin Reef scatter symbol is the treasure chest. This scatter symbol does not trigger any sort of bonus round but it does pay out when three; four or five of them appear on the reels. Pay outs are three; ten or one hundred coins respectively. The treasure chests must land consecutively but unlike the other symbols they are considered winning combinations regardless of whether they land from left to right or right to left.

The Dolphin Wild and Re-Spin Feature

The Dolphin Reef wild symbol is represented by the featured creature itself. The dolphin wild symbol will only ever appear on the second and fourth reels and when it does it assists in forming winning combinations if they are possible by acting as a substitute for any of the symbols including the scatters. The wild will also expand to cover the entire reel which results in more possible winning combinations.

Like wilds in many mobile casino slots at, when the dolphin wild symbol appears on both the second and fourth reel simultaneously, the Dolphin Reef re-spin feature is triggered. When this happens both of the reels become entirely covered in the dolphin wild symbols and the first, second and third reels spin a further five times for free. At the end of the five re-spins the wild reels resume to normal for the next paid spin.
