About Royal Gems slot

Good morrow knights and maidens of Castle Jackpot, we’ve got a glistening addition to our collection of slots online that we think falls right under our remit with the mention of royal in its title. Developed by Red Tiger, Royal Gems slot is set against the backdrop of a castle’s treasure room and is strewn with golden coins, gem stones and treasure chests. Offering thee more ways to win through its unconventional locking cluster system and its use of super gem symbols which can land on any spin across the 8x8 online slot reels, could you find the higher payouts?

There is no shortage of Gem themed slots here in the castle keep with Starburst slot and Gem Blast two of the personal favourites of our King and Queen. Yet Royal Gems has earned its place in our listings as the symbols used across the expansive reels aren’t just limited to one size with rubies, sapphires and diamonds appearing in either 2x2, 3x3 or massive 6x6 size. If you continue to add more gems of those colours during each spin, they’ll lock in place, and could win you a 2x multiplier if you fill the entire reels with clusters.

Royal Gems Slot Bonus Features

Locked Clusters

While spinning the reels of Royal Gems online slot, if the gem symbols form a winning combination, they will be locked in place for the next spin. On the next spin, if a matching gemstone joins that cluster a new payout is made, and the cluster remains in place. This format will continue until no new matching symbols join the existing clusters or create new ones.

Crown Upgrade

If thou art lucky enough to land the crown symbol anywhere on the game reels, it will fly across the grid and upgrade the existing cluster to higher-paying symbols, which can mean higher payouts.

Full Screen

During any spin of the reels in Royal Gems slot, if clusters are formed and cover all 64 gem spaces on the reels the final payout available to jousters will be doubled.

Super Gems

Throughout any full spin of the reels, larger versions of the available gemstones can appear on the reels in either 2x2, 3x3 or 6x6 size format. These can offer thee larger payouts and can be locked with smaller symbols to create clusters.
