How to Play

To start playing Dr. Jekyll & Mr. Hyde, do the following:

  1. Open the title on a browser page
  2. Click on the "?"
  3. Check out wintable
  4. Bet between €0.3 and €90
  5. Spin the reels to your heart's content

The title has 30 paylines and 9 regular symbols, from which you can create combinations on a 5x3 playing field. There are also several Wilds here. The first one can turn into Mr Hyde and occupy any reel completely. The 2nd and 3rd in the base game are combined, turning into 2 separate Wilds during the bonus round.

Also, the slot has many useful features that allow you to customize it according to your preferences. For example, you can switch the control to left-handed mode, as well as turn off/on the music and sounds in the slot.

Dr. Jekyll & Mr. Hyde RTP and Volatility

8.1 
The RTP of the slot is 95.60% and the volatility is high.

The return percentage is a theoretical indicator that displays the amount that you can return at the end of a gaming session. Please note that RTP can only be relied upon in theory, since the outcome of each spin cannot be predicted. In addition, for the return percentage to work, you need to do about 1,000 spins, and possibly more.

High volatility is a good sign for risky punters. With this indicator, the slot will pay quite rarely, and the prizes will not be small.

Theme

8.7 

The game invites you to immerse yourself in a gloomy city of the 19th century, where gas lamps flicker in the streets, and in the alleys, you can meet the real Jack the Ripper. The playing field almost disappears against the background of an ominous fog creeping along the sidewalks, and what is at the end of the dark street in the background is completely impossible to understand. The atmosphere is conveyed correctly, and the flashing of the lantern after each spin only confirms this.

The musical accompaniment of the slot is also made with taste and knowledge of its subject matter. Throughout the game, a great melody sounds, which at the same time uplifts the mood and makes the gameplay more reckless. When prizes appear on the grid, the slot responds with a muffled hiss that only complements the overall soundtrack.

The symbols of the game are 4 card denominations from J to A, as well as the Parchment with a feather, Cigar, Police Helmet, and Jekyll himself with his evil alter ego Hyde.

A regular-game Wild, made in the form of a laboratory table, can turn into the Hyde and take up an entire reel during the base game. In addition, the slot has a double free spins symbol depicting the Police Badge and Dr Hyde's potion. It splits into two separate ones before the start of the bonus round.

Bonus Rounds & Free Spins

7.5 

Wild Feature

There is only one Wild in the base round of the game. It is depicted as a laboratory table with various alchemical accessories. This symbol can suddenly disappear in a greenish smoke, and in its place will be Mr Hyde, who occupies the reel completely. Interestingly, more than one such Wild can appear on the screen.

Free Spins

The split Scatter symbol, representing Hyde's green potion and the Police Badge at the same time, can appear on the screen in triplicate. In this case, a bonus round consisting of 20 free spins will start. If 4 or 5 Scatters land, you will receive 30 or 50 free games respectively.

Before the round begins, either the Police Badge or Dr Hyde's potion must be selected. Each of them will turn into a Wild with special features.

  • The Police Badge becomes a sticky Wild that gradually spreads vertically
  • Dr Hyde's potion moves to the left with each new spin

It should be noted that these features are available only during free spins.Dr. Jekyll & Mr. Hyde Slot - Free Spins

Max Win

6.4 
Maximum win – 4,000x the bet.
There are some really big payouts available in the game, but they are not easy to get because there are not very many bonuses here. In fact, to increase your chances of winning, you need to wait for the start of the free spins round. We advise you to carefully monitor the progress of the game so as not to lose your bankroll before this happens.

Overall Rating

7.7
Dr. Jekyll & Mr. Hyde is a very colorful and exciting title with a lot of interesting features. By triggering the bonus round, you can really increase your chances of winning big prizes. However, beginners might find this slot attractive but a bit difficult to learn. We recommend that you play the demo before playing for real money.
