As source material for a slot goes, it doesn’t come much more unlikely than the 19th French biologist Louis Pasteur. A good pun goes a long way in the online casino world and that’s the case in Greener Pasteur (geddit!), a madcap 5 reel, 30 payline slot from 2 By 2 Gaming.
This science-themed game comes with a random germ feature that transforms symbols into the top paying symbol, a random cash prize or a wild. Also on offer are free spins. Enter the lab from between 30p and £30 per spin.
An anarchic laboratory is the setting for Greener Pasteur – joining the lower value playing card symbols are chemical flasks, a trio of grinning germs, a syringe, a microscope and the slightly deranged looking biologist. The most lucrative symbol is the Greener Pasteur logo – land 5 of these for a payout of 800 coins.
The magnifying glass is the game’s wild, appearing on reels 2 and 4 only. As well as substituting for all other symbols apart from the scatter, it also awards multiplier prizes of 2x, 3x or 4x whenever it forms part of a winning combination.
Greener Pasteur comes with a Free Spin feature which is triggered by landing the milk carton scatter on the middle 3 reels. As well as a payout of your total stake, you’ll also be given 12 free spins. It’s possible to re-trigger more free spins so hope to see those milk cartons spin into view – you will 8 more.
In both the base game and the free spins round, you can benefit from the Special Germ feature – blasts of gas will fire from below the reels and in the process turn germ symbols into either the top paying symbol on view, a cash prize or a multiplier wild. A new payout is then made with the new symbols in place. Expect to see the Special Germ more often in the free spins.
Greener Pasteur is a light-hearted affair – the visuals have a cartoon quality and the action plays out to a bouncing backing track. We found the variance here to be in the medium range. The free spins come along at fairly regular intervals and paid solidly. We never found a real bumper payout there though.
This strange, science-themed slot is an enjoyable romp. The grass may not be greener on the other side but it’s certainly enjoyable finding out. As far as science goes, I recommend The Lab from ELK Studios or Cyrus the Virus from Yggdrasil Gaming.
