Expert's review Martin Anastasov

Slot tested

Thank goodness that these are butterflies and not moths because the latter wouldn't have fared well as part of the title of this amazing game by NetEnt.

Butterfly Staxx gives away the two defining features of this game: there are butterflies aplenty and they can form staxx, which goes to a specific effect in a game that can pay up to 25,000x your bet.

This is one of those games that I see available in a good share of online casinos, and every once in a while I can't resist giving it a chance to surprise me.

Theme and Graphics

Flowers and butterflies are somewhat of an unlikely theme for an online slot, however, it has been created masterfully by NetEnt and made to offer a gaming experience on a unique idea.

The golden, shimmering butterflies tend to be the most ubiquitous symbol on the reel-set, but it occurs in the company of flowers and the royal cards' symbols.

NetEnt have given Butterfly Staxx a composed appearance, as the game's symbols are steady on the reel-set until they become part of a winning outcome.

But despite the placid appearance, I find the gameplay dynamic since each time a staxx of butterflies is formed on any of the reels, the game can go off on a roll of respins, which tend to result in wins that are at least two times greater than the wager.

Extra Features

Whether you like this game at the very start depends on the whim of the butterflies. These can interact with the wild symbol and lead to better wins on the respins. But this isn't all to the game, as there is a free spins feature.

  • Butterfly Respins

    The bioluminescent insect is the highest-paying symbol on the paytable and can appear as a solitary symbol or it can come in one or more full stacks of four along the reel.

    Each time a full stack lands on a reel, all four butterflies will fly to the first reel, along with any of the additional matching symbols that have appeared anywhere on the reel-set.

    The symbols remain in place while the rest are sent away in a respin, which can result in additional butterflies that also fly towards the left to join the stacks.

    Respins are awarded for each additional butterfly that appears on the reels until there are none left, in which case the game counts the winnings.

  • Butterfly Spins

    This is the name of the free spins game, which is triggered by three, four or five scatter symbols; these outcomes generate five, six, and seven Butterfly Spins in that order.

    In the event, you are taken to a screen filled with cocoons, one in each position across the four rows and five reels. Each spin can reveal either none, one or more butterflies, which then mimic the same which they do in the base game: fly to fill up the leftmost available position on the reel-set.

    Each spin that results in butterflies can count for a winning outcome, while additional butterflies can make the subsequent wins even stronger. It goes to the player's favour that Butterfly Staxx comes with 40 paylines, as this number is more welcoming to the better share of butterflies landing across the reels.

    Personally, I find this bonus feature preferable to a classical free spins moment, at least for this game. This bonus is similar to the Hold and Win type of a bonus feature, with the exception that you get a fixed number of spins, which can't be retriggered.

Bets and Payouts

It is typical of NetEnt to enable a wide range of coin values and bet levels on their slots. Butterfly Staxx is one such game that has the smallest coin value of one penny and £2.00 per a fixed Bet amount of 20 so that a coin value of 5p results in a total bet of £1.00.

Players who want to up the ante can increase the Bet Level in order to wager bigger amounts against the game.

Not surprisingly, I found the payouts to be on the weak side, however, this is balanced out by two key factors: the frequent appearance of butterfly staxx and low volatility. On yet another positive note, the theoretical RTP is 96.80%.

The category of high-paying symbols includes blue, purple and red flowers and the butterfly symbol. The latter pays 15x the bet stake for three, 30x for four and 60x for five symbols.

Minor symbols are jack, queen, king and ace; each kind pays the same, fixed amounts: 5x for three, 10x for four, and 20x your bet stake for five matching symbols.


There is a reason why Butterfly Staxx is still popular, so much so that I think it is more memorable than its sequel Butterfly Staxx 2. The butterflies make the game unpredictable, which goes both ways. At times a full stack results in more than one respin, and the winnings that come of it, while other times a stack doesn't pan out anything in return.

I find the free spins bonus quite enjoyable as the butterfly symbol is the only thing that can emerge from the cocoons, so there is always the possibility that each of the 20 positions gets populated by that symbol. With 40 paylines across the board, this is a great way to make outcomes with a big pay potential.

For closing thought, I would definitely keep Butterfly Staxx on the menu, not that I've ever tasted any in real life - nothing which a trip to a few specific countries wouldn't cure.
