There are wilds, a gamble feature, a non-progressive jackpot of 25,000 coins as well as a progressive random jackpot amount that fluctuates with every coin that’s played – you wouldn’t expect all that from a retro slot machine.

Playing this game can be done from as little as 0.40 a spin but if you are a high roller, those stakes can be increased to a maximum of 100.00 a spin. The more that’s bet per spin, will result in higher returns and a bigger non-progressive jackpot sum.

Gaming Design

Styled on a classic fruit machine, the 5 Line Mystery slot machine is designed to resemble the other slot games in this series of classic machines. The reels are placed centrally and the machine itself is a purple colour. The paylines pierce through the reels to highlight the 5 different paylines on offer. To the right you will find the bonus panel with a cash amount that alters with every spin. Beneath the bonus meter you will find the gamble feature.

To the very lower of the reels is the player control panel, allowing you to alter your bets to suit your budget. You’ll also find buttons for autoplay, the paytable, the start button and the gamble feature beneath the control panel.

The symbols that make up this a slot game are; jokers, red 7s, cherries, oranges, lemons, golden stars, plums and watermelons.

Slot Stats

Featuring 3 reels and 5 fixed paylines, players can adjust their bets accordingly at any point of gameplay. Minimum stakes are 0.40 and they return a maximum non-progressive jackpot of a minimum of 1,000 coins. Bet maximum stakes of 100.00 and that non-progressive jackpot will turn into 25,000 coins.

High rollers betting maximum stakes will need to search for the red 7s to be rewarded with that non-progressive jackpot.

Bonus Features

To start with, you have the mystery bonus cash amount – this is triggered by spinning in three jokers on your payline. No matter what you stake – you will be awarded a guaranteed cash sum. The amount you can receive fluctuates from spin to spin, so it could be 5,000 coins on one spin and 1,000 coins on the next. This is what makes 5 Line Mystery slot machine so intriguing as you never know what you are going to receive.

Next you have the Mystery Game which is designed to resemble scratchcards. Six different panels will be displayed on the screen with differing cash amounts, these are situated beneath the win and bonus panels. These cash amounts will be covered up and will shuffle on your screen. You are required to select one of the six to unveil a prize. This prize will be credit to your account and the remaining five panels will be unveiled.

The panel that you selected will now display a ‘X’ inside. You will get a second attempt at winning more cash. Four panels now display cash amounts, one will display the X and the other the bonus – this awards the amount displayed in the bonus panel. You can continue on this bonus until you unveil the X or uncover all six cash amounts – including the bonus prize.

Gamble allows you to gamble any base game win that you trigger on your reels. Guess the correct colour that the light will come to a stop on and you will win. It’s a 50/50 game of chance allowing you to double your cash or lose everything.

Mystery Machine

In our opinion, 5 Line Mystery is the best slot game in the classic slot series from Novomatic. The mystery element adds even more excitement to your gameplay – this amount will flash as the reels spin and land on an amount as the reels come to a stop.

There are so many ways to accumulate cash and the mystery bonus allows for some huge wins. We found this slot machine to be of medium variance which featured a return to player (RTP) percentage 95.00%.
