Personal testers opinion about Butterfly Staxx

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 the free spins 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. 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 for the wagering rating. 16% of bets are reserved for the payment during the free spins feature. From the other hand, I have a lot of times when streams were playing Butterfly Staxx via the high stakes and win a lot during first re-spin or the free spins feature. 

Review and recommendations by the testing team

Winning in Butterfly Staxx slotOne 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 a high value, even the full lines are quite cheap, that will not let you get a bigger balance, you will hardly keep the one you had in the very beginning.
  • You will not get a bonus as often, except the "bursts" which sometimes may drop, after 100, 200 and even 300 spins you could probably find yourself in a game without a single bonus.
  • The bonus itself is nothing special, 2 out of 5 spins are usually empty, the other 3 close three reels. The average winning during the bonus game is х80-120, 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 somehow got you. 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 down as fast.
  • The slot has a low dispersion value, you will hardly keep your balance up while playing it, not recommended for playing the bonus games. It has a recommended x300 or more.
  • Recommended game strategy: up to 50 spins, leave after getting a win from a х50, regardless the way you got it, be it during the bonus game or a normal game re-spin.
  • Ps: Note that providers regularly change the slot scripts, which may lead to a different slot behaviour. The BNC team will do its best to keep you updated on the changes made! Remember that these are just some of the schemes and examples, you could find a completely different slot behaviour!

  • 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 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.

  • 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, Butterfly re-spin feature can be triggered. To launch it, you need any whole reel filled by 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 free spins feature), creating the winning combinations.
