Royal Double

Players on the lookout for the best online slots will want to pay close attention to Royal Double, the old-school title from Tom Horn Gaming.

This three-reel mini-slot punches well above its weight class.

To go along with a very appealing vintage design, there are instant cash prizes of up to 10,000x the bet size, up to 40 free spins at a time, and strong overall RTP, as well as plenty of chances for players to double their win size.

Theme

“Royal Double…”

… may be an evocative title, but what does it mean?

In this case, the “Royal” refers to the jester wild symbol. This icon substitutes for other symbols (except bells and 7’s) while also offering base play’s top payout of 5,000x.

“Double” points to something very different indeed…

… all gaming symbols may appear on the reels with an “x2” marker. Such symbols award twice their normal value on winning combinations.

These symbols include many of the classic icons found in slot gaming since time immemorial. These include cherries, lemons, oranges, plums, grapes, and watermelons. Lucky 7’s lead to a bonus mystery prize up to 10,000x!

This Tom Horn Gaming title’s most gaming important symbol, however…

… is the golden bell scatter symbol. This is the gateway to free spins, gamblers’ best opportunity for big wins in this title.

Betting Options and Functions

There are 27 fixed pay-lines, all paying from left to right. The overall per-spin bet range is set simply from 0.10 – 100.00 times the betting currency. ‘’Autoplay’’ is available as a simple on/off toggle, though players should exercise caution, as there are no win/loss limits available.

Player options, pay-line information, game rules, and more are available via an expanding menu at the lower left corner of the game screen. The overall theoretical return to player ratio is very strong at 96%.
