The Spin Lab from NextGen Gaming is a science themed slot machine featuring samples of DNA and atoms. The graphics are nice and the background music and sound effects are pleasant. The special feature of the game is definitely the exciting free spins, as they allow you to choose enhancements. The game is best for players that want to play a slot for a while and wait for the free spins. Once you manage to trigger them, you will find that it was well worth the wait, as you can win a lot of money if you make the right decisions.

The wild symbol

The colourful wild symbol replaces other symbols to complete winning combinations, but it does not replace the scatter symbol. When you manage to get the symbol five times on a pay-line, you will also win 1000 coins.

The scatter symbol

Three more scatter symbols will start the Spin Lab free spins bonus game. If you manage to get 2 or more scatters on the screen, you will also be awarded a coin prize. The scatter symbol pays out regardless of its position on the screen.

The free spins bonus game and the enhancements

The slot machine features a very unique free spins game that is triggered when you get 3 or more scatter symbols anywhere on the reels. You will then be awarded an initial 5 free spins. Then you have the option to select several enhancements that will be applied during the free spins. You can choose a total of 3 enhancements from a selection of 9. They are divided into rows, and you can pick one option from each row. In the first row you have to make a decision about the high-paying symbols. You can choose to have them all treated as one previously selected random symbol, have a selected symbol appear stacked, or to have a randomly selected symbol award a coin prize whenever it appears. In the second row you can decide how the wild symbols are treated. Make your choice from either getting stacked wild symbols, extra wild symbols, or a random wild multiplier of up to x10. In the third row you can make your selection about the game. You can either have all your winnings doubled, enable winning combinations to be possible from both ways, or to get five additional free games. As you can see, the pick and mix feature from the slot can make it incredibly rewarding if you choose the right features, and of course if you are lucky. However, even though there are just five free spins, you can win a lot of money.

Gambling your winnings

The slot gives you the option of gambling your winnings after each winning round. You can select a card colour for a 50% chance of doubling your winnings, or you can select a card suit for a 25% chance of quadrupling your winnings. You can leave the gamble at any time by clicking on Collect.
