As Elk's The Lab is entirely based on a scientific theme, its background is a space vortex, which is akin to a black hole. A spinning disk on the screen pulls in the stars and space matter around it, and that gives the game a sense of sci-fi modernity. As the spiral spins constantly behind the reels, it makes the symbols behind the reels appear to hang in the deep space, just like they're hanging in deep space.

The wagering controls can be accessed by clicking the bet amount on the bottom right of the screen, which will allow you to adjust the bet per spin as high or low as you wish. It also contains a unique feature that allows you to set different types of betting strategies, such as raising the bet amount as you lose the bet, for instance. It would be fine if you designed your own plan, of course. As you can see, the elements that appear in this space-based slots lab are the blue symbol of water H2O, the purple symbol of oxygen O2, the silver symbol of platinum Pt, and the gold symbol of gold Au.

It is important to remember that if you land three or more of these in a row, you will have a chance to win and the prize values will begin to increase from water at the lowest level of wins to gold at the highest level of wins, where you may be able to win up to 60 coins if you land five of them in a row. Secondly, there are the crystal molecules that come in a variety of colors, such as pink, purple, blue, and green. It is important to know that payouts on these spins range from 3 symbols upwards, from pink at the lowest level to green at the highest level, where you can strike up to 1000 coins at the highest level.

As scatter symbols, the X symbols function as multipliers, which means that they increase the size of any win you receive whenever they appear anywhere across the reels. There is no doubt that this feature can be particularly useful after the free spins feature, when a big win can be multiplied even further. There is a Lab symbol located on the second reel of the game and this is one to look out for. As soon as it lands directly over the vortex on the center line on the top of the slot machine, the free spins feature is instantly triggered. Upon triggering this feature, you are rewarded with free spins to try and hit those big payouts that are waiting for you. The Lab symbol will also turn into a wild symbol when this is triggered, as well as triggering the sliding reels feature.

During the course of the game, the wild Lab symbol can be substituted for other symbols along the paylines. This means that when you are playing the free spins feature, there are many opportunities for you to seriously boost your total, often resulting in a big win overall once the spins are over. The Lab is an interesting and unique science-themed slot game that has a fun and pretty nifty bonus game as well as a feature where you can win free spins. Why not take a trip into space today and play free slot games on your computer, smartphone or tablet, straight from the comfort of your own home.
