A popular underwater slot
Dolphin Reef keeps things simple: 5 reels, 3 rows and 20 lines, with a cast of sea creatures. The clownfish is the top symbol, followed by the sea turtle, then the starfish and seahorse pair. The card symbols A, K, Q, J, 10 and 9 fill the lower part of the paytable.
It is one of the 12 Mega888 games BolehSpin players opened most in the last 30 days, so it is often the first slot people try in the Mega888 H5 lobby.
The dolphin wild
The dolphin is the wild and substitutes for all symbols. The help page gives it no pay value of its own, so its job is to complete lines for other symbols.
Its second job is more important. When a dolphin lands on reel 2 and another on reel 4 at the same time, the free games feature starts.
How the respin feature works
The help page explains the feature step by step:
- Any wins from the triggering spin are paid first.
- Reels 2 and 4 expand, and every position on those two reels becomes a substitute for all symbols, including the scattered chest.
- Reels 1, 3 and 5 are respun 5 times while reels 2 and 4 stay wild.
- For the chest pays, each expanded reel counts only once.
- The feature uses the same lines and bet as the spin that started it, and its wins are added to your line and scatter wins.
Treasure chest scatter
The treasure chest is the scatter. Five chests pay 100, four pay 10 and three pay 3. The help page does not say whether these amounts are multiplied by your line bet or your total bet, so check your win display after a chest hit.
Red or black gamble
After a win you can try the gamble screen: guess whether the next card is red or black. A correct guess pays even money, so your win doubles; a wrong guess loses it. Press Collect to keep the win and go back to the reels.
