Who lives on the reels
The ocean cast is split into four pay levels. A grey shark and a green sea turtle pay the most of the regular symbols, followed by a yellow striped tropical fish. An orange seahorse and a purple starfish share the next level. The letters A, K, Q, J, 10 and 9 are drawn as blue bubbles at the bottom of the table.
The orca wild
The killer whale replaces any symbol except the pearl scatter and doubles all wins it is part of. On the paytable, every regular symbol has a pink WILD column next to its normal value: a line of five sharks reads 750, and the WILD column shows 1,500 for the same line with an orca in it. The orca on its own pays 10,000 for five.
Pearls and the shell bonus
Three or more pearl scatters anywhere open the bonus. Before you pick anything, you are already given 8 free spins with a x2 multiplier. Then five pink shells appear and you open two of them.
- A shell can add free spins, raise the multiplier, or do both.
- The help page gives the top as 33 free spins or a x15 multiplier.
- Three or more pearls inside the bonus add 15 more spins, keeping the multiplier of the spin that triggered them.
- The page states that further free spins can keep being won.
The gamble screen
When you win, the Gamble button opens a card screen. It shows BET, LAST CARDS and DOUBLE TO, so you can see what is at stake. Pick RED or BLACK for the next card, or press COLLECT to keep the win and go back.
Not covered by the help
The MAJOR, RANDOM and MINOR numbers at the top of the main screen are not explained. Line direction, RTP and maximum win are not given either, so this page does not mention any.
Playing it sensibly
Twenty-five lines add up quickly, so look at the total bet beside the line count before you start AUTO START. Treat the gamble as optional, set a stop point for the session, and keep it as entertainment.
Great Blue at BolehSpin
You will find Great Blue in the Mega888 lobby at BolehSpin. It runs in H5 straight in Chrome or Safari, so there is no APK to install and no extra Mega888 ID to remember.
