Royal Tumble™ by Dragon Gaming is a low-volatility slot with 1,024 fixed paylines, 4 rows and 5 reels. It uses standard playing-card symbols, including Jacks, Queens, Kings, Aces, number cards and suit icons. Wins pay from left to right, and matching symbols can trigger cascading reels, where winning symbols are removed and replaced by new cards for another chance to land a combination.
The game’s main mechanic is the wild upgrade system. After each cascade, one picture card may be upgraded to a wild, with successive upgrades carrying higher multipliers until the 20th consecutive win. A progress bar tracks this sequence, and wild symbols substitute for all symbols except the scatter. The RTP is 95.00%, and the demo version can be used to play for free and practice before playing for real money.
Three scatter symbols unlock the bonus game, which mirrors the base round and awards 8 free spins. The bonus can also be triggered with the Buy Bonus option. During the feature, symbol replacements may gain multipliers, and the round can finish with a choice between two cards for a possible extra free spins award.
