About Dr Jekyll Goes Wild slot

In Dr. Jekyll and Mr. Hyde, authored by Robert Louis Stevenson, the respectable Dr. Jekyll turns from time to time into the hell-mad Mr. Hyde. The story goes that this doctor, tired of his day job, concocts an elixir that turns him into a primitive, brutal, and barbaric version of himself—Mr. Hyde. He simply wishes to live without cruel repression of his baser instincts. And yet, every time he takes the potion to become free and wild, he comes back again and again to be the good Dr. Jekyll who must live in good standing.

Developers of the game, Barcrest, have done an excellent job of lifting Robert Louis Stevenson’s story straight off and creating a slot where in the dark alleys of London we get to meet both Dr. Jekyll and Mr. Hyde. With an extremely distinct Victorian style to both the graphics and the sound, we as gamers are supposed to feel transported back to the second half of the 19th century when playing this slot. If you're a history buff and can stomach mystery and horror-themed slots, this one is a no-brainer.

The concept behind the game is fundamentally straightforward. You play 10 predetermined lines with a wager ranging from $0.10 to $500 per line. When you manage to get two or three wins on a row, you secure a payout. But the real enjoyment comes during the free spins when you can play two different variants of the game and spin an effectively boundless number of times.

Stakes and winnings

The game has coin values ranging from $0.10 to $500.00 and offers 10 fixed paylines. With that in mind, the cost to play a single spin on the game can vary between $1.00 to $5,000.00, which is a huge range and makes the game suitable for all kinds of players.

The maximum you can win playing Dr Jekyll Goes Wild is 250,000 coins. This is a huge max win! Hitting that amount might be virtually impossible, but it's nice to know that the game can be incredibly generous when it's in the mood. And that's what makes this game such a classic at land-based casinos.

Dr. Jekyll Goes Wild has, interestingly enough, three different sizes of return to player over time (RTP). What makes this even more intriguing is that the size of the bet determines how much you get back with this game.

When wagering amounts less than $20, you will receive a poor RTP, specifically 94.20%. If you make your wager at $20 or higher, the RTP suddenly jumps to a decent 96.20%. The best RTP you can get while playing with Big Bets is a very nice 98.20%.

Symbols

Barcrest / Scientific Games has dropped five one-of-a-kind paying icons into the game. Those icons are as follows: the logo, a depiction of Big Ben, a streetlight, a rack holding five test-tube-sized items, and a piece of parchment with a goose quill. For the other three paying icons, which pay less than the icons mentioned above, the developers went with rehashed versions of the trusty old playing card symbols (A-10). But at least in the case of the Big Ben symbol, it's unlike any other paying icon in the history of video slots. Also, it's worth mentioning that you can tell the difference between the five test tubes and the paper with a quill, but not much between the Big Ben symbol and the Ace of Spades.

Game features

The free spins rounds are where "everything happens" in Dr Jekyll Goes Wild. If you are a fan of Free Spin features that come with a plethora of specials, and present the player with the opportunity to spin along an endless line of successive free games, then this is a game you cannot overlook.

Free Spins

A symbol that stands for both the Good Doctor and his belligerent counterpart is the free spins scatter. Three, four, and five of these icons, respectively, will award you 10, 15, and 20 free spins. You play these with the same stakes and lines as the base game. If you happen to get more Jekyll symbols on the screen, you win even more free spins.

You get to play with something special in the feature, which is that Dr. Jekyll takes on the role of wild. Also appearing on the reel for the first time is a new symbol. This symbol, which represents the eponymous elixir, gives you the chance to play Hyde Spins.

Hyde Spins

If the elixir symbol lands on reel 1, the free spins round will change to the feature Unlimited Hyde Spins. This round has no fixed end and can go on for eons.

An hourglass appearing on reel 5 will either end the round or continue with more Hyde Spins. If the bonus ends, the game will resume in Jekyll Free Spins mode, given there are spins left to play.

Naturally, Hyde Spins also has a wild feature, and this is much more pronounced compared to the Jekyll Spins function. Every symbol depicting Hyde is a wild, and when a joker appears, it locks into position. A joker that shows up in the same round as the elixir symbol not only is wild (which already makes it awesome), but also becomes sticky (for an even better win chance). The wild and sticky joker feature means this round could be very good indeed.

This sticky wilds feature can help you achieve a winline, which means a line that pays in almost every spin. It is yet another feature we have seen before in NetEnt's Dead or Alive. And if you trigger this particularity with a Big Bet, it is going to pay off in a level that it wouldn't even if you were to trigger it with a regular bet.

Big Bet

Like several other Barcrest slots, Dr. Jekyll Goes Wild features a Big bet. The concept behind such features is to offer players the chance to produce more lucrative outcomes, or hits, from the game. In exchange for doing so, players pay a bit more for their spins.

When you place a Big bet, you begin by first paying an additional large bet on the board. You then receive five spins of the reels. The crucial element here is to look for the symbol that shows both Dr. Jekyll and Mr. Hyde. The more of these symbols that appear, the more free spins you get to play in Jekyll Free Spins mode (up to an incredible maximum of 75!).

If you stake $ 200, at least three symbols are needed to yield free spins (5). Stake $ 300, and three symbols will get you 10 spins. Stake $ 400, and with two symbols, you're in the bonus round. Stake $ 500, and you're still using just two symbols to net you 10 spins. In total, you have six symbols to play with, yet the maximum number of spins you can get is 75 and that's only if you have the right combination of those six symbols.

Summary

Dr. Jekyll Goes Wild truly is distinct from the other slot offerings and presents a captivating way of triggering its Big Bet feature. Once you're in the Bits Spins round, you're kind of forced to enjoy the experience because you sit through around 20 games and get a couple of superb chances to go excellent i.e. enter the "free spins part." So, if you like to play for even more reason, this game gives it with a hell of a lot of flash.

Key details to understand and never forget are that RTP varies by stake level. Basically, if you're only playing for low amounts, you're really not in a profitable range when we look at things over a long stretch of time. On the other hand, not every player is comfortable with moving up the stakes. So, we suggest you first get a feel for the game by playing for free (like you can in the review above) and then step up to playing for higher amounts. Also, try out the Big Bet feature to get a feel for how the game works at a different intensity level before you dip into your bankroll to play for real.
