Butterfly Staxx Slot Review
There’s an unusual theme, look, and feel to Butterfly Stax slot, a release from summer 2017 that’s already proved enough of a hit that it’s inspired a sequel.
You can try the free play demo for Butterfly Staxx on this page before exploring more online slots or comparing UK casinos.
Flowers, butterflies, and a tropical night sky aren’t classic online video slot looks. We hate to stereotype (something no-one ever says without immediately stereotyping, so accept our apologies), but this design might be considered more female-friendly than some of the classic slot themes.
We’ve seen more of this style of games recently, with new themes and more whimsical, gentle, and even ecological graphics being used in games.
There are more differences than just the look and feel though, and the first one that hits you is the bigger playing area with four rows of symbols.
NetEnt can’t have got to their position in the market without getting things pretty right, but should you head off to this beautiful tropical jungle to see if a butterfly stacks on your reels?
Let’s have a deeper look in our Butterfly Staxx slot review.

The Facts and Figures
The Butterfly Staxx slot is a low volatility game. These much-misunderstood measure plots win frequency against win size: games that pay out bigger prizes tend to do so less often, and these games have “high volatility”. Reverse the ratio – lower prizes paid more often – to get a “low volatility” (the measure is also called variability) game.
The theoretical return to player records how much of the money a game received in its lifetime it should (if players behave in expected ways) return to players. For Butterfly Stax, this RTP is 96.8%, which is pretty high, though only marginally so. Most players better understand this figure as representing a “house edge” of 3.2%.
The top single pay-out is a very nice 240,000 coins, which is paid out at the top of a staking range that runs from 0.2 coins to 400. (Usually 20p to £400 in the UK, but please check staking and pay-out limits in the site you’re using.)
The layout is non-standard, with five reels (as usual) and four rows (against the usual three) to give players a 20 symbol playing area, across which run 40 pay lines.
If you have a device that runs JavaScript and HTML5 you should be in business to load up and play Butterfly Stax slot.
The Game
Playing this game is very simple, and the controls follow a standard pattern for this developer.
The control panel runs across the bottom of the screen on a desktop, with, at the far left, the Bet window, which is set with a level control to the right of the full stake. The centre of the panel is the play button, which is flanked by a max bet button and the autoplay function.
To the right of that, you complete your betting decisions with the coin value control. Finally, your balance is recorded.
Look for further controls in the game frame.
How to Win
The information controls in the frame will open up the pay-table for you, and this is what it will tell you.
The lowest paying symbols pay out for sets of between three jacks and five aces.
Then we have flowers and butterflies, in this order:
Blue flowers; Pink flowers, and finally Butterflies, which start paying out from just two symbols.
There is a scatter and a wild. Startlingly, both are simply the word in question!
Butterfly Staxxby Slot Bonuses
Scatters trigger the Butterfly Spins round.
Three scatters gives you five spins, four give you six, and five give you seven.
The free spins come with new cocoon symbols. These are either active, turning into butterflies, or dormant, doing nothing. Butterflies fly to the left to complete wins and then remain on the reels until the round ends.
Respins are triggered in the base game. Butterfly symbols stack to fill a reel and trigger a respin. Butterfly symbols fly to the left of the reels and lock on the reels until respins end, which happens when no more butterflies land.
Wilds act as you would expect them to!
The Verdict
NetEnt keep ‘em coming, and Butterfly Staxx slot arrives looking slightly different but delivering everything you have come to expect from NetEnt.
There’s a great top prize on a good range of betting with very generous RTP. The low volatility means that you’re likely to enjoy long sessions on this game, though if you stake at the top of the betting range, the 240,000 top prize is one of the best.
NetEnt make games that look and play fantastic. The Butterfly Staxx slot is no different, with a nice take on staking symbols and some real variety in the bonus games. We like the theming that makes a pleasant change, is easy on the eye, and very well delivered.
Come out of your cocoon today and see if you’re destined to be a beautiful, big-winning butterfly! There’s no better game to stretch your wings on.
