Gold Lab is styled as a big lab of some weird scientist, who always has an uplifted mood. The background is some as-if scientific facility with huge playfield in the center shaped as some sort of potions conveyor and a scientist standing on the left is waiting for nice combinations to occur.
When at least two of framed bottles appear on the screen, one reel gets one re-spinning to catch luck to have the third similar framed bottle on the screen. If it does, then the scientist guy rejoices and does some action with a potion, pouring it into his potion pod, from where the liquid is poured in one of four test-tubes located on the right. They are filled in randomly but depending on a type of the framed potion that was screened. After this, a series of free spins starts, ranging from minimum 4 for one filled test-tube.
During the free spins, your bet is frozen and it keeps rolling until the free spins are stopped. In the free spins round, you receive an increased chance of winning, and the total win is calculated and added until the round stops. During it, you may be lucky enough to fill in another tube of potion (from one to three extra). In this case, after filling every, you receive one extra free spin, and a chance to win huge.
Ordinary wins during a free spin may be around 300 euros (with a normal bet in 10 euros, but you should bear in mind that bets range from 0.1 euro to 100 euros, and this is set manually by you).
During 200 spins betting 10 euros each time, you have a proven middle chance to win around 1.000 euros normally (in demo mode) but the RTP is somewhere around 96.06%.
Gold Lab - The x-times you may win range from x2 to x413, depending on the type of symbols you see on the screen.
The symbols are test-tubes of 4 kinds, 5 types of gemstones, and 4 framed tubes – wild symbols triggering the bonus game.
You can also make an automated game (with a possibility to stop at any time).
