Great Blue is the deep-ocean slot the Malaysian Mega888 community talks about most — not because it pays often, but because when the bonus lands, the amount can be far larger than a typical slot round. The developer-published RTP is 96.5%.
Its defining feature is the clam bonus round. You collect Scatters to trigger it, and the clam you pick decides how many free spins you get and what multiplier applies — up to 33 spins with multipliers as high as 15x. That combination of many spins and a high multiplier is what produces the big wins players share screenshots of.
Understand one thing before you play: high volatility means your balance will dip more often and for longer stretches between bonuses. If your bankroll is small, your per-spin bet needs to be small too, so you have enough spins left to actually reach the bonus. Most players who bust out do so not because the game is bad, but because their bet size was too large for their bankroll.
An honest note: the RTP figure on this page is the number published by the game developer, not a result we measured ourselves. RTP is a long-run average across millions of spins — it does not predict what happens in your session. Gambling carries a risk of losing money. 18+ only.
