Monster Lab

Monster Lab is a mad-scientist slot from Evoplay in which the reels are specimen tubes holding a cast of odd creatures. It runs on five reels, three rows and 20 paylines, with four colourful monsters at the top of the paytable and smaller critters below.

The feature set is generous for a medium-volatility game. Expanding DNA wilds land on reels 1, 3 and 5, molecule scatters award up to 25 free spins, and when the round ends a card pick offers win multipliers or 20 more spins. A bull bonus symbol adds a separate bonus game. The RTP is 96.0 % and bets run from 0.1 € to 100 €, a good fit for players who enjoy layered features.

Three matching symbols on one of the 20 lines win. The blue creature is the premium symbol at up to 100x the bet for five, and the other top monsters start at 1x for three. The pink creature, the bird, the trunked creature and the snake are the low tier, paying 0.2x to 7.5x the bet.

The DNA-strand wild appears on reels 1, 3 and 5, expands when it lands and substitutes for everything except scatters and bonus symbols. Three, four or five molecule scatters trigger 15, 20 or 25 free spins, and the round can be retriggered. Once it ends, you pick a card for win multipliers or 20 extra free spins. Three or more bull symbols start the bonus game.
