The Sea of Riches slot game has a standard variance and an average RTP of 96%, so you can reasonably expect regular payouts if you play the game for a long period of time. What is especially noteworthy about the Sea of Riches slot online is that it isn’t a regular payline slot but a cluster-pays game. This format is steadily gaining popularity for reinventing the slot machine experience. Wins are no longer formed on paylines or even ways, but rather in clusters, which is why the grid is much larger than usual. Clusters start from five-of-a-kind symbol combinations and can be formed with at least 15 symbols overall in the Sea of Riches online slot. As long as the symbols’ edges and corners are touching each other, they will form a cluster and make up a win. The symbols in the game consist of gems in vibrant colours, along with coins made of various metals. The ruby is the most lucrative symbol, with a 150x payout for 15 symbols or more in a cluster. The wild has no payout of its own but can substitute for any missing symbols needed to score a winning spin. You’ll also find bottles on the reels, which are needed to boost the game’s level. Collect 25 bottles to move up a level, which each come with generous modifiers like symbols turning into wilds and multipliers added to wilds. What’s more, every win in the Sea of Riches slot machine will trigger a random modifier for the subsequent spin such as symbols transforming into the same symbol, cascade reels, the removal of low-paying symbols and more. If you’re lucky, you could also trigger the free spins bonus round.
