If you like to play online slots with a cute theme at an online casino with free slots, you can’t go wrong with Butterfly Staxx and Butterfly Staxx 2 at The Phone Casino. Check out our reviews of each game to learn more about these titles.

Butterfly Staxx

As you may have guessed, butterflies and other beautiful elements of nature are at the centre of Butterfly Staxx, a 5×4-reel slot from NetEnt, the developer of hits such as Gonzo’s Quest and Starburst. This wonderful slot has 40 paylines and offers players an RTP (return to player) of 96.8%. It’s a low-volatility title, which means players stand the chance to win more frequent but smaller prizes.

Graphics and soundtrack

As with many NetEnt titles, Butterfly Staxx undoubtedly features some incredibly polished graphics. The game plays out against a mountain backdrop at dusk, with fireflies fluttering in the background. The reels are surrounded by greenery and a blossoming tree, creating a calming atmosphere for players to enjoy.

The reels themselves are populated with various beautiful plants for both the regular, wild and scatter symbols, as well as green ace, king, queen and jacks for the regular symbols. The highest-value symbol in the game is, of course, the yellow glowing butterfly.

The animation in this title is more calm and serene than flashy and eye-catching, but it works with the overall design of the game.

Soothing electronic-style music plays throughout, with gentle sound effects occurring when the player spins the reels. If you get a win or trigger a bonus feature, uplifting sound effects play to let you know.

Bonuses and features

Butterfly Staxx keeps it fairly simple, with features that you’d find in many other slot titles including wilds, respins, and free spins. Wild symbols can substitute for all symbols except the scatter and can appear anywhere on the reels. Respins are triggered when an entire column of butterfly symbols appear on the reels. These symbols will move to the far left to replace any that aren’t already butterflies. This will keep occurring during your respins until no more butterfly symbols appear, marking the end of the Respins bonus game.

One of the extra bonus games that you won’t find in other titles are the Butterfly Spins. This mini-game is triggered by landing three to five scatter symbols, which then reward you with five to seven Butterfly Spins. In this feature, cocoon symbols will land with each spin, with specific ones transforming – as in nature – into the game’s iconic glowing butterfly. These butterfly symbols could award you with big wins, depending on how they appear.

Players could win 640x their wager when playing this online slot.

Butterfly Staxx 2

The sequel to the mellow and calming online slot we discussed above, Butterfly Staxx 2 builds upon the experience offered by its predecessor. Again the action takes place on a 5×4-reel with 40 paylines, but this time the game offers an RTP of 96.35%. Volatility that varies from low to medium means players of this slot could possibly see regular, smaller prizes, or a mix of smaller and larger prizes.

Graphics and soundtrack

The sequel takes a similar approach to its graphics and soundtrack, offering players a more relaxing experience, especially compared to many other online slots that focus on thrills and excitement. This time, gameplay takes place against a stony window that looks out towards a blue sky and a lush forest. Surrounding the stony window are plants with gently swaying beautiful pink flowers, as well as little balls of light that float around, adding life to the game.

The reels are home to various flower symbols, as well as symbols for the ace, king, queen, and jack. The glowing butterfly again takes centre stage, but this time it’s got a more detailed design, with its wings featuring clearer patterns.

Just like the first game, animations are smooth and gentle, avoiding being unnecessarily flashy or over the top.

When it comes to the soundtrack, the sequel features music that is now even more relaxing than the first title. Wins are again punctuated again by upbeat music that combines with the blooming flowers around the stony window, serving to highlight the importance of your win even more than the first game.

Bonuses and features

This game offers much the same experience as the original Butterfly Staxx with its wilds, scatters and free spins. However, the Butterfly Spins from the original game is also still available to play, as well as a new bonus game called Butterfly Frenzy, in which players reveal hidden prizes by selecting butterfly symbols that appear on the reels. You can choose from one of these games when you land three or more scatter symbols.

Players could win 240x their wager when playing this online slot machine.
