Great Blue by Playtech: Gameplay Explained
What is Great Blue?
Great Blue is a Playtech title listed in HappyBingo’s catalog. This educational article focuses on sea shells and free-game modifiers. The game format is listed as five-reel, 25-line slot. The sections below explain the documented sequence and identify details that require the specific edition’s help screen.
Gameplay: Sea Shells and free-game modifiers
Great Blue's published help describes line wins and a separate Scatter evaluation. Three or more Scatters start Sea Shells with eight free spins and a two-times multiplier. Two shell selections then add free spins or increase the multiplier.
Feature sequence and gameplay details
During the feature, another qualifying Scatter group adds fifteen free spins while preserving the multiplier. The Wild also has its own substitution and doubling rules. The source distinguishes line-based awards from Scatter awards calculated against the total stake.
Understanding the terminology
A Wild substitutes only as allowed by the paytable. An expanding Wild occupies more positions, while a sticky Wild remains for a defined sequence. These are different properties. Neither property, by itself, tells you the chance of starting a bonus or receiving a particular award.
