Here are a few of our favourite mystery slots:

Jack Hammer 2

This is an example of a slots game that was originally launched as a sequel but ended up becoming more popular than the original. Jack Hammer and Jack Hammer 2 are both made by gaming giant NetEnt. NetEnt is a Swedish gaming firm that originally made its name in the land-based casino business. Over the years, it has become far better known for its extensive online offerings - with slots such as Jack Hammer 2, it is not hard to see why.

This is an original and genuinely entertaining game that offers something different from the standard five-reel slots layout. The biggest selling point of this spy-themed slots game is that every time you land a winning combo, you get at least one more spin for free. Winning combos are made up by three or more matching symbols on consecutive reels, starting with the leftmost reel. When you land a winning combo, you will notice that instead of paying you instantly, the game kicks into respin mode. The reels spin again, with the winning combo staying in place. When the reels stop, any further symbols that contribute to the existing winning combo or create additional winning combos stick in place. The reels then spin again, which continues until no new winning combos are created. You will be paid out at this point, hopefully after building up a substantial winning combo (or several).

There is also a free spins bonus feature, which is triggered by landing five or more free spins scatters on the reels. If you land three or four, they will stick in place and the reels will spin again, giving you another chance to land five in one go. The free spins feature works in the same way as in the base game, with multiple chances to win with every spin.

Agent Jane Blonde

It would be hard to avoid this slots game even if you tried, as it appears on countless sites all over the world. An online slots classic, Agent Jane Blonde surely must be one of the most-played mystery slots of all time. Created by Microgaming - one of the biggest names in the business and responsible for some of the most-played slots ever - this flashy-looking game is sure to appeal to anyone who enjoys mystery-themed slots. Clearly based on the James Bond franchise but replacing James with a woman, the game is a stylish and enjoyable slot. With its comic book-style illustrations, it certainly stands out from most of the other identikit slots out there at the moment.

Although it is simple to play, there are quite a few options when it comes to setting your bet, so new players might be confused initially. It is all very straightforward, however, and you simply have to choose your coin size, number of lines and bets per line. The total bet amount displayed will change as you adjust the settings, so you can keep on top of what you are betting. As this is a nine-line slots game, the payouts are decent. The free spins feature is triggered when you land three or more scatters on the reels and has the potential to be very lucrative if you get lucky.
