Special Features of Great Blue

The bonuses in Great Blue are what truly elevate this slot. The Scatter symbol, represented by a giant clam, can trigger the free spins feature when it appears three or more times on the reels. This is where the real fun begins.

If three or more Scatters appear during free spins, 15 additional spins are reactivated with the same multiplier. This can create impressive combinations and large prizes.
