Personal testers opinion

You will have to wait a long time until the slot machine gives out a combination of three scatters and triggers the bonus free spins feature. The probability of triggering this feature is below the middle line - 0.24% (every 417th spin). My average winning from it was only 43x.

As for the usual spins, the maximum winning was 229x total bets. 86% of the prize pool is reserved for the usual spins. You can try to complete the wager requirements for bonus money as it has 6.24 points out of 10 possible. 16% of bets are reserved for payment during the free spins feature. On the other hand, I have a lot of times when streams were playing Butterfly Staxx via the high stakes and win a lot during the first re-spin or the free spins feature. 

Review and recommendations by the testing team

One of the most popular slots among NetEnt fans. Many would expect big wins from it. Well, let's see how generous the "butterflies" are :)

  • If talking about the winning combinations of all symbols except the butterflies, the provider did not give them high value, and even the full lines are quite cheap, that will not let you improve your balance, you will hardly keep the one you had in the very beginning.
  • You will not get a free spin feature as often, except the re-spin feature. Sometimes you will have to wait for 200 - 500 spins to trigger the free spins feature.
  • The free spin feature itself is nothing special, 2 out of 5 spins are usually empty, the other 3 close three reels. The average winning during the free spin features is 80x - 120x total bets, not impressive at all, given the low chance of getting one.
  • However, the butterflies you get during the normal spins and which are added to a re-spin are helping with your balance keeping. You may get this feature quite often, but the additional butterflies that would give a really good combination are rare enough. Nevertheless, it will not let your balance fall as fast.

The slot has an average dispersion value, that's why we will leave neutral recommendations for fulfilling the bonus requirements. It has a recommended bet balance of 300x total bets or more. Recommended game strategy: up to 50 spins, leave after getting a win from a 50x bet, regardless of the way you got it during the free spin feature or a normal game re-spin feature.

Description of the slot machine

Deciding to continue the series of Staxx, started last summer (for example Neon Staxx slot), the developers created the machine with 5 reels and 40 lines. The formation of the pay combination occurs only from left to right. Butterfly re-spin and bonus free spins feature not only allow you to diversify the gameplay but often lead to the appearance of the inscription of "Mega Win".


  • Provider of the slot machine - NetEnt
  • Number of reels - 5
  • Gaming Lines - 40 (always active)
  • The cost of one coin is from 0.01 to 2
  • Number of coins per line - 1-10
  • The range of bet sizes ranges from 0.20 to 400
  • Wild symbol - yes
  • Scatter - yes
  • The free spins feature - yes (triggering with 3 scatter symbols). The player gets 5 free spins. During the free spins feature all symbols are cocoons which can be converted to butterflies. They fly to leftmost positions and stick there, forming the combinations. 
  • The bonus re-spin feature - yes. The whole reel of butterflies triggers it. Re-spin continues until any new butterflies appear on the reels. All butterflies fly to the most left free position and are sticky there until the end of the re-spin feature. It has a big potential for winning but usually ends after 2-3 re-spins.
  • The RTP (return to player percentage) in the online slot is 96.8%

Symbols and payments

  • Card symbols can bring the player from 5 up to 150 coins on every line.
  • Flowers symbols can bring a player from 50 up to 250 coins.
  • Butterflies are the top symbols that can pay up to 600 coins.
  • Wild does not form its combinations. It only replaces all symbols except scatter.
  • Scatter is a purple flower with a corresponding inscription. The appearance of a bouquet of 3 - 5 symbols launches the bonus game with free spins.

The free spins feature

Dropping 3+ scatters triggers the Butterfly free spins feature. You will get 5, 6 or 7 free spins, during which only green cocoons will appear on the screen. After each stop of the reels, a part of the cocoons turns into butterflies, and they shift to most left positions.

The re-spin feature

During usual spins, the Butterfly re-spin feature can be triggered. To launch it, you need any whole reel filled with Butterflies. Re-spin will come and if on any position new butterfly will fall - new re-spin will be triggered. All Butterflies fly to the most left positions (same as during the free spins feature), creating the winning combinations.

How to win at Butterfly Staxx slot machine? (conclusion)

And this time we will begin a paragraph as you expect: always test the slot machines in a demo mode before depositing real money. A good strategy you can use here is "Hit and Run". Try with 50 - 80 spins and if you trigger any bonus features with a win from them around 50x total bets, it is good to change the game after this. It is good to choose big and popular casinos because we think it has lost little of its popularity, and in the big online casinos will be easier to collect the prize pool. Recommended bets are average. The slot machine may be pretty good for bonus hunters, but best try to determine the "mood" before you start.
