Castaway Cove Slot by Relax Gaming

The reels hang from torn pirate sail-cloth, pinned to a wooden frame with the wreckage of a galleon visible just over the left shoulder. Waterfalls cascade down dark cliffs on the right, a stone skull formation looms behind, and a half-buried treasure chest sits on the sand below. It looks like a Saturday-morning cartoon version of Skull Island, and that cartoonish tone carries through to the symbols: weathered pirate captains, a navy-coated lieutenant, and four colours of golden ring as the low pays.

The grid is wider than it looks at first glance. Six reels by four rows with 466 connected ways replace traditional paylines, so symbols pay across adjacent reels rather than along fixed lines. Wilds substitute for everything except the bonus tiles, and there are five distinct chest variants (CH1 through CH5) that act as the engine for the whole game.

Coins are the thing to watch. They drop on the reels carrying multiplier values, and chests landing alongside them collect everything currently visible, with single chest landings advertised as paying up to 2,000x. Trigger Free Spins from Relax Gaming's scatter cluster and the chest tier you collect upgrades the coin values for the duration of the bonus, so a CH1 grab during base play and a CH5 grab during free spins are very different beasts. The maximum return is capped at 4,364x, which sits at the modest end for a high-volatility chest collector and tells you something about how the variance is distributed.

Bet range stretches up to 200 EUR per spin, double what most Relax titles allow, with no buy feature on the MT build. If you've played the Dream Drop sister, this is the same beach without the progressive jackpot pool siphoning off the maths, which means a fatter base return and a higher ceiling on stakes in exchange for losing the six-tier prize ladder. The tropical-island scenery and the chest mechanic carry over identically, so picking between them comes down to whether you want jackpot exposure or a cleaner base game.
