The Spin Lab Slot Machine - Demo, Free Play ,Game, Casino

The Spin Lab slot machine was first released by NextGen Gaming in 2015. It immediately attracted both penny punters and high-rollers thanks to the wide betting limits that range from $0.40 to $1000. The high return to player ratio of 95% makes the slot more appealing for the prospective winners of a $50,000 maximum win. The casino game has a classic 5x3 layout with 25 pay lines. The lack of a jackpot wheel may be disappointing but is easily made up for by the special features. The bonus options of the Spin Lab slot include free spins and multipliers, as well as progressive free games. The game is available to play for free, so players can sharpen their skills before making actual wagers. You may need to play demo version to figure out the game’s functionality.

The Spin Lab Slot Demo Review

The Spin Lab game is another project from NextGen in which you can now play in demo mode on our website. The video slot was designed to attack your free time and offer a unique theme that other developers rarely use. 

NextGen introduced this game in April 2015. Despite the lack of a progressive jackpot, you can still win 50,000 coins, and it is easy to do with the bonus options and special symbols that are often used in video slots of this brand. All of this takes place on 5 reels with 25 active paylines. Keep reading to find out more. 

How to play this slot

The good news is that the Spin Lab casino game is available on desktop devices and smartphones/tablets. This gives gamblers freedom because they can play anywhere with Internet access. Whichever device you choose, the gameplay will be comfortable. 

To take part, wager at least 40p. Thanks to the low entry threshold, this slot machine is suitable for many players. To bet, use the appropriate button on the control panel. Pay attention to the fixed lines. Playing with 25 betways gives many ways to make combinations. 

The speaker button turns the sound effects on and off. The adjacent ‘i’ key opens a section with a paytable and several pages with general rules. Once you have read the rules, return to the main screen and start the game by pressing the big green button on the right. The Autoplay feature is available as well. It plays spins in an automatic mode, not requiring your participation. 

Finally, the video slot is equipped with a Gamble button. It is not available throughout the game, activating only when you become a winner. This is a mini-game to increase the payout, and we’ll talk about it a bit later. 

The Spin Lab slots symbols and soundtrack 

Modern three-dimensional visuals attract attention from the first seconds. This works perfectly with the thematic soundtrack devoid of loud sound effects, helping players focus on the winnings.

If you’re missing one symbol to win in the Spin Lab slot, use the Wild. This substitutes for all characters except for the Scatter, which by the way, appears quite often. Both symbols pay. You get 1,000 coins for five Wilds and 625 more for five Scatters in any position.

The basic set of symbols is represented by:

  • Cube.
  • Atom.
  • Molecules.
  • DNA.
  • A & K.
  • Q & J.
  • 10 & 9.

As soon as five Cubes appear on the screen, 800 coins will go to your account. For Atoms, Molecules, and DNA, you will earn 600, 500, and 400 coins. A & K offer 200 coins, and the remaining card suits pay 100 coins. 

This may not be the greatest variety, but the symbols offered form winning chains often. In addition, the video slot works with 95% RTP. 

Bonus options

To enter the bonus round, at least three Scatters need to appear in any position on the Spin Lab slot machines reels. Initially, gamblers have 5 free spins and the ability to choose their own additional options. You can pick one feature for each of the three sections.

Row 1

  • Symbols are the same. One of the four most-profitable symbols of the basic set is randomly selected. During the spins, the pictures will turn into this symbol. 
  • Symbols stacked. All these symbols are again involved, and one of them will be stacked during the bonus.
  • Symbol prizes. By randomly selecting one of the symbols, you will receive a generous cash reward when it appears on the screen.

Row 2

  • Stacked wilds. During a bonus, each landed Wild becomes stacked.
  • Additional wilds. More Wild symbols appear on the playing field. 
  • Wilds + multipliers. The reward for any combination of wilds is multiplied by 2-10x. 

Row 3

  • Multiplier (all wins). Any winnings obtained in this bonus will be doubled. 
  • Pays both ways. This option in the Spin Lab slot machine means a payout for combinations in both ways. They can start from the first left reel or the first right reel. 
  • Extra rounds. You will get +5 free games and more chances to win, respectively. 

Is that enough? We think this is a great set of options and bonuses, even though there is no jackpot wheel. 

Pros and cons of the slot 

On the first impression, free The Spin Lab slot is bright, attractive, and at the same time simple. The only bonus option is very interesting, although sometimes it takes a long time to trigger it. Regardless of whether you play with the minimum or maximum bet, there are high chances of winning.


  • Wild combinations pay generously. 
  • Free Spins bonus with different modifications.
  • Multipliers.
  • Low entry threshold.


  • No turbo mode.
  • The only bonus round.
