Grand Blue

Overview

Grand Blue is presented by Fa Chai as a Megaways-style slot with a theoretical return of 96.59 % and what the studio labels as “Medium-Low” volatility. The official win cap sits at 3,500× your stake and the feature set lists Free Games, an Increasing Multiplier and even a Progressive Jackpot. That mix is unusual: a relatively modest top prize paired with a volatility band that is softer than most Megaways releases.

Key facts

• Confirmed (official): 96.59 % RTP, Medium-Low volatility, 3,500× maximum multiplier, Megaways payline engine, features include Free Game, Increasing Multiplier, Retriggers, Buy Feature and Progressive Jackpot.
• Listed elsewhere (unverified): Variable grid shown as 5-6-6-6-6-5 with up to 32,400 ways; stake range €0.80 – €1,000.

What this means for a player

• The 96.59 % RTP is comfortably above many modern studio averages. Over very long play it trims the house edge to about 3.41 %.
• A “Medium-Low” volatility tag suggests gentler bankroll swings than typical Megaways titles. Expect more small/medium hits and fewer droughts, although confirm in practice because the label isn’t a mathematical guarantee.
• The 3,500× cap limits life-changing payouts but keeps the prize ladder achievable. If you chase single-spin jackpots in the 10,000×+ zone, this game won’t scratch that itch.
• Because of the lower variance and capped potential, it suits bonus wagering requirements, casual sessions and players who simply want frequent interaction with features.
• If the Buy Feature is offered in your jurisdiction, weigh the cost carefully; with a 3,500× ceiling it rarely makes sense to pay more than 100× for instant entry.
