Revealing a winning combination on any of the high-paying symbols will unlock grand rewards with the symbol lock re-spin feature. The winning royals lock into place as the reels re-spin in hope of landing more of the same symbol. Re-spins continue until no further matching symbols land on the grid.
Each time you land royals, you influence the symbol upgrade meter, a chandelier each side of the slots. The first time you land nobles on a spin, the chandelier begins to glow, resetting once more if you don't land any nobles. A second consecutive spin landing nobles makes the chandelier glow brighter still, and a 3rd consecutive spin landing royals triggers the upgrade feature which transforms your royals to the next highest paying symbol.
This lavish royal garden ball has no wilds, scatters, or free spins, but the collective re-spins, symbol lock and symbol upgrades feature keep things interesting. The max payout of 300x also appears small, but Rising Royals does have a reasonable RTP of 96.01%. With a max bet of $250, this slot can pay out $75,000 on a spin.
