Great Blue Slot — RTP, Max Win & Features

About Great Blue

Great Blue is one of Playtech's enduring classics — a 5-reel, 25-payline underwater slot with a 96.03% RTP at high volatility and a 10,000× max win.

How it works

Two or more Great Blue scatters trigger the free-spins round (up to 33 spins) where the Killer Whale wild doubles any win it joins and stacked multipliers can build serious payouts. The whole game lives or dies on that bonus.

Our take

A genuine old-school favourite with a strong 10,000× ceiling for its era. RTP is operator-configurable (you'll see builds from ~94.25% up to 96.58%), so check the in-game panel — but the headline 96.03% is fair, and the free-spins multiplier potential is why it's stayed popular this long.

The RTP reality

Great Blue's published RTP is 96.03%. RTP is configurable, so the same slot can pay back differently from one casino to the next. The only figure that reflects your game is the one in the slot's own info ("i") panel at the casino you're using.
