Greener Pasteur Slot Review

Viruses and bacteria might be fascinating stuff, but it’s hard to imagine that anyone would want to put them into an actual slot game. And yet, that’s what 2 By 2 Gaming have done with their Greener Pasteur slot that was released in 2015. Is it any good, however? Well, that’s what we’ll be looking at in this review!

Theme and Graphics

Bacteria and viruses, eh? So how does that work? Well, it’s actually quite simple and what we like is that the game isn’t taking the theme too seriously, so what you can expect to see on the game’s reels is a nice mix of funky viruses, crazy doctors and various laboratory stuff.

Unfortunately, 2 By 2 Gaming couldn’t do away with the classic set of card symbols and that is a big minus in the context of the theme, as it tones down the creativity factor by quite a bit. We aren’t going to pretend that it kills the slot, but we do believe that you should always try to get the most out of silly themes.

And the game’s audio? Well, that’s nothing special either, so we are struggling to praise Greener Pasteur for how it looks and sounds. Given the unique theme, it really does seem to be a missed opportunity.


Now that we’ve covered the slot’s audiovisuals, we should turn our attention to its gameplay features – and we’re naturally going to start with the Wild symbol.

In Greener Pasteur, it comes in the form of a magnifying glass and it works as a substitute for all the other regular symbols. It can appear only on reels 2 and 4, but the interesting bit is that it also doubles as a win multiplier, so there’s certainly some silver lining to the deal.

Next, there’s the Scatter symbol that looks like a carton of a milk and that can appear only on reels 2, 3 and 4. And what’s going to happen once you get three or more of these symbols in a single spin? Well, you’ve guessed it – you’re indeed going to activate the slot’s Free Spins feature.

The initial batch that you can get consists of twelve free spins, but you can get eight additional ones by finding more sets of Scatters, so it’s possible to get some really nice chains if you’re lucky.

To round things off, there’s also the Special Germ feature that’s triggered on a completely random basis (although the chances of it appearing do increase during all free spins). And what does it do? Well, it does something with all the germ symbols – and there are actually three different outcomes. First, it may turn them into the top-paying symbols. Second, it may turn them into Wilds. Third, it may transform them into random coin wins.


Greener Pasteur builds on a playing field that has three rows and five reels, so there aren’t any real surprises waiting for you on this particular front. Meanwhile, the number of paylines was set to 30.

They’re all fixed, so you can’t really tinker around with the setup, but you can choose from a reasonable range of betting levels. It is slightly disappointing, as there’s just one slider that players can use in order to adjust their desired stakes, but it’s far from being disastrous. In practice, you can play for as little as €0.30 or as much as €30, which ensures that Greener Pasteur remains accessible for all kinds of players.

Finally, we’d also like to mention that the game’s theoretical RTP (return to player) has been set to 96%.


When everything is put together, we’ve got some seriously mixed feelings about Greener Pasteur. On one hand, it’s a game that has a very quirky theme and reasonable gameplay features. On the other hand, its audiovisuals are nothing to write home about and the interesting theme seems to be incredibly under-utilized.

It really does feel that developers should be able to do much more with themes this creative, so we feel obliged to give the slot a thumbs down for not living up to its potential. That said, there’s nothing wrong with the game apart from that, so chances are that you will be able to get some hours of fun from it. Just don’t go in expecting a polished experience!

Where to Play

2 By 2 Gaming, the company behind Greener Pasteur Slot, might not be among the most important players on the slot gaming market, but they have managed to get their games to a fairly decent number of online casinos – and we’d very much like to recommend the Mr Green casino to everyone who’s interested in giving the reviewed slot a go.

First of all, these guys have a fabulous gaming arsenal that features hundreds of interesting slots from all kinds of developers, including NetEnt and Microgaming. That would be quite good on its own, but there are also some treats for players that prefer classic casino games like roulette and blackjack – for example, Mr Green have all kinds of live casino Roulette tables on standby 24/7, so you’ll never have any issues finding one to sit down to.

Secondly, Mr Green are basically a dream come true for those who like gaming on the go, as the mobile apps they offer for iOS and Android systems are arguably the very best around. You don’t even have to trust us on this point – just look up how many awards they’ve already won for them! Not forgetting that they have quite low min. deposit limits of 5 pounds for many payment methods.

And the kicker? Mr Green are one of the very few online casinos that have an actual personality, so you can expect to witness some truly hilarious writing and promotions during your stay!
