Detailed review about Butterfly Staxx Slot

Butterfly Staxx The Swedish developing studio is conversing with us via sparkling butterflies and blooming tropical flowers. Elegant, innovative animations, plus electronic but serene music, will magnetize us during the gameplay, where the fluttering creatures will eventually go through the (generous for the player) metamorphose from cocoon to a Butterfly.

This is a Low Volatility slot with an RTP (return to player percentage) of 96.8%. If you want to know – one of the most preferred pages by experienced players is “How to win at Starburst slot”.

Personal testers’ opinion about Butterfly Staxx slot (Review and recommendations from the testers’ team)

At first glimpse, you can be mesmerized by the well-designed animations and relaxing soundtrack of the Butterfly Staxx slot. The unique pay mechanism is wonderful to watch.

However, except for the Butterflies, the other symbols’ combinations are very low-paid. 3x the bet for a 5OAK top symbol! You soon realize that only makes a significant difference if it happens on multiple lines, preferably on all 40 of them – to generate 120x the bet amount for a full screen of 20 Butterflies – it seems insufficient, to say the least!

In fact, the whole paytable is a bit “cheap”- even 5OAK will not help to improve your balance, and you can hardly keep your beginning capital steady.

Throughout our game test period, we made the following observations:

  • The Butterflies you get during the base game Re-Spins feature are trying to help with the progress. During our test with a couple of hundred spins, the Re-Spins were activated very frequently, but only 75% of them ended with a win, while the other 25 % had no additional butterflies. From the winning percentage – the highest win we received was a rough 55x the bet. All in all, a really good paid combination from Re-Spins is rare, but the function will not let your balance fall fast.
  • You need a lot of patience to receive the 3 Scatters triggering the bonus Free Spins feature (sometimes you will have to wait for 200 – 500 spins). The Free Spin feature itself is nothing special; 2 out of 5 spins are usually empty. The average winning during the Free Spin feature is 80x – 120x the bet, not impressive, given the low chance of getting one. This slot machine has the probability of triggering this feature below the middle factor – 0.24% (i.e. every 417th spin). Our test group average winning here was only 43x the bet.
  • 86% of the prize pool on this slot is reserved for the usual spins.
  • During the usual spins, our test group record was 229x the bets.
  • 16% of the bets are reserved for payment during the Free Spins feature.
  • The Wagering here is 6.24 (out of 10) and, together with the slot’s low dispersion, makes us give neutral recommendations for fulfilling the bonus requirements. You can try to complete the requirements for the bonus money, but this is not the most suitable NetEnt slot for that.
  • Butterfly Staxx has a recommended bet balance of 300x the bet or more.
  • On the other hand, we observed many times streaming exhibitions of playing Butterfly Staxx with high stakes, winning a lot during the first Re-Spin or the first Free Spins.

Slot’s symbols and features

  • The video slot has a 5×4 playing field with 40 fixed pay lines.
  • The unique slot mechanism produced by NetEnt introduces a one-of-a-kind Butterfly Re-Spin feature being initiated by a vertical fluttering group of 4 Butterflies (stack) landing on any reel.
  • On the low side of the paytable are the card letters – JQKA, the medium paid symbols are the 3 flowers, and the top paid is the golden Butterfly.
  • The exception here is that 2 butterflies are also a paid combination.
  • Wild is one lotus flower- substitution for all symbols (except Scatter).
  • Scatter is a small rose bouquet randomly appearing on all reels.

Butterfly Re-Spin Feature

A vertical stack of 4 Butterflies on any reel is triggering the Re-Spin function of the base game. The stack flutters left – becoming sticky, and grants 1 Re-Spin, during which any additional Butterfly dropping will activate another Re-Spin making the new Butterfly edition joining left the ‘old’ locked stack. This repeats until there is no further Butterfly symbol landing.

Butterfly Free Spins

3, 4, or 5 Scatters on any reel will reward with 5, 6, or 7 Free Spins. During the Free Spins, only symbols of Cocoons are displayed on the screen, where after the stop of the reels, random Cocoons will be converted to Butterflies.

Just like in the Re-Spin feature, they will flutter left, becoming sticky till the end of the bonus round. Any 2+ Butterflies on a pay line will be rewarded. All the bet line wins are added to the total win with every next Free Spin as well.

How to win at the Butterfly Staxx slot? (Conclusion)

As usual, our first advice is to test the game in DEMO mode before starting to play for real money. It is good to choose big and popular Canadian online casinos to play this game because we think it has lost its popularity, and in the big online casinos, it will be easier to collect the prize pool.

We do recommend the Butterfly Staxx slot to bonus hunters, but only:

  • If bonus hunters tested the machine to define if it is “hot” or “cold” (in DEMO), and
  • If they place average bets around 10 CAD (not higher).

We recommend the following game tactic:

  • “Hit and Run.”
  • Try with 50 – 75 spins, and if you trigger any bonus features with a win from them around 50x total bets, it is good to change the slot after this.
