5 Line Mystery Slot Machine Casino Game
Bonus slot machines or bonuses in general are features in slot games that can range from free spins, free games, spin and bonus multipliers, or double or nothing features, just to name a few. With free online slots, the variety is endless, whereas before, players did not have nearly the range to choose from as they do today.
If you are looking for a modern version of a classic Euro-slot (the type you see in bars and cafes around France, Italy and Germany), then this 5 Line Mystery slot machine will probably appeal. The style of game is different from the slots you get in Vegas, but a lot of people adore this simple style of play.
We have a free version of 5 Line Mystery slots here (below). The game should just take a few second to load if you have a decent internet connection and you can then play for free for as long as you like.
The game requires no download and you do not need to register to play.
5 Line Mystery is a 3x3 reel slot machine with 5 pay-lines, produced by Novomatic. The main theme is a nostalgic recreation of old, physical machines that used to be popular in just about every gambling den. Living up to the name of fruit slot, it offers cherries, lemons, oranges, plums, watermelons and grapes for gamblers with a sweet tooth. Alongside them, you will find jokers, which act as Wilds, and stars, which are the gateway to a bonus game.
The main feature of this pokie is the random jackpot visible on the upper right corner of the screen. While Novomatic do not share how the value is determined, it always sits much higher than your wager, making it a real good prize. To win it, you need to get three Joker symbols in a single pay-line, which will reward the sum determined for that spin by the bonus counter.

Alongside this special feature, three stars lead to a simple bonus in which activate the Mystery Game feature. It will reveal six panels with cash prizes displayed, before they flip over and begin to shuffle. After that, you take a pick between the shuffled panels, and win its value, which is added directly to your stash.
Best Free Slots With Bonus
5 Line Mystery offers you high variance gameplay, which fits with physical machines most of the time. Its payouts aren’t great by themselves, as they are mostly there to keep you afloat while you chase the Mystery Game or the Bonus prize. Alternatively, you can make good money by guessing red or black to double your prize, but if you guess wrong, you lose everything.
5 Line Mystery in UK, NZ and AU
Australians and New Zealanders won’t have any trouble trying out and enjoying this pokie from Novomatic. And given the popularity of fruit machines in the United Kingdom, it’s no surprise the developers have made it available there, too.

This slot machine has 3 reels, each with 64 stops. The game picks 3 random numbers from 1 to 64, one for each reel, and maps them to a symbol on the corresponding reels. The reel stripping was carefully constructed to achieve a return of 96.9%, on average. For more information, please see my full design of the game.
I designed a single-line version of this game in August 2008, when I was asked to speak to the Gaming Technologies Association, in Australia, on the topic of slot machine design. It took a while to find someone who could do the graphics, but the wait was well worth it. I would like to extend my thanks to Dingo Systems Inc. for the artwork, and JB for putting the graphics into my design in the form of a JavaScript game for you to enjoy.
