Special Symbols

The special symbols in the game are The Lab Wild and the X-Scatter multiplier. The Wild will replace all other symbols in the game during the free spins bonus only. The X-Scatter multiplier will double the win on the reels, when it lands with a winning combination.


The Lab is a 5 reels, 3 rows slot with a total of 15 active pay lines. Players can bet anywhere from $0.15 to $90 per spin. The bet size is adjusted by clicking on the Bet button and choosing the appropriate bet size. Players can also use the betting strategies which the slot has in stock. If you activate the Jumper strategy the bet level will increase after each win on the reels, before it reaches 4 levels above the base level. The Leveller strategy increases the bet level 2 steps after 5 consecutive losing rounds. If another 5 loses occur the bet level is increased for another 2 steps. The Booster strategy will increase the bet level one step after each losing round, until you reach 4 levels above the base level.

Bonus Round

The X-Scatter Multiplier will multiply the winnings by x2 if it lands on the reels along with a winning combination. When the Lab Wild lands on the second row on reel 2 the free spins bonus is triggered. You are awarded with 10 free spins, where the surrounding symbols on the reels slide over to the last 3 reels. The first two reels will spin giving you a chance to form big wins. All payouts during the free spins are doubled in size and you have a chance to win more free spins. Extra free spins are awarded when the +1 or +2 free spins symbol lands anywhere on the first two reels. The trick in this feature is to get matching symbols around the Lab Wild in order to have a bigger chance to get 5 of a kind wins during the feature.


The top payout in The Lab comes from the Green Crystal. It awards a payout of 1,000 coins if you manage to land 5 of them on a winning payline. Since the symbols can land stacked on the reels you can get several winning combinations on the reels with the top paying Green Crystal symbols. The top payout per spin is set at 30,000 coins if you manage to win a full screen of Green Crystals across the reels during the free spins bonus.
