Our Review of Butterflies II
Butterflies II Slot: A Veteran Look at the Math and the Moment
Butterflies II is WGS Technology’s modern repaint of a very old idea. It is a five reel, fixed line video slot with upgraded visuals, a single on reel feature, and very little clutter. This is a game for players who like straightforward math, line driven wins, and do not need free spins or layered bonuses to stay engaged.
What the Reels Are Actually Doing
Butterflies II runs on a 5x3 reel set with 25 fixed paylines. All wins pay left to right starting from reel 1, with line wins built from 2 or 3 of a kind upward depending on the symbol. The layout is classic video slot, so anyone who has played older WGS or RTG titles will recognise the structure immediately.
Regular symbols handle the bulk of the hit rate. Low and mid tiers fill the screen often and keep small line hits flowing. Wild symbols sit in the mix and substitute for all regular icons except the scatter. The scatter pays anywhere on the reels for 2 or more, but it is strictly a pay symbol and does not carry a feature trigger.
Because there are no free spins and no separate bonus round, every spin in Butterflies II resolves on the main grid. The only exception is the Butterfly Feature, which is really a second evaluation of the same outcome after extra wilds are added. That keeps the game state simple and makes it easy to track where the value is coming from.
The Feature Set, Mechanic by Mechanic
- Wild: The standard wild symbol substitutes for all regular symbols except scatters. It appears in the base game and during the Butterfly Feature, and it is the main way the math stretches ordinary line hits into something more meaningful. Because the slot has only one real feature, wild coverage is critical. Stacked or clustered wilds across the center reels can drive the better line hits, especially when combined with the Butterfly Feature adding more wilds on top.
- Scatter: Scatter symbols pay out for two or more anywhere on the reels and multiply the total bet. They do not need to land on a payline and they do not trigger free spins or any side game. Mathematically the scatter is there to add a second layer of small to medium pays on top of line wins, which helps smooth the hit rate in a game that otherwise leans on one feature. Players used to scatters acting as a gateway to free spins should be aware that in Butterflies II the scatter is cash only.
- Butterfly Feature: The Butterfly Feature is the signature mechanic in Butterflies II. It triggers whenever the Butterfly House symbol lands anywhere on reel 1. First the game pays out any regular line and scatter wins from the spin. Then a butterfly appears from the house and flies to random positions on the reels, turning those symbols into wilds. The grid is then re evaluated and any new or improved line wins created by the added wilds are paid.
- Autoplay: Autoplay lets the player set a stake and a number of spins, then let the slot run. All normal rules apply, including the Butterfly Feature, wild substitutions, and scatter pays. There is no change to RTP or volatility. It is simply a quality of life tool for those who prefer a more passive session on a low complexity game.
Max Win Reality Check
External reviews put the top payout in Butterflies II around 3,000 times the bet. That figure requires a very strong combination of high paying symbols and wilds, likely with the Butterfly Feature dropping extra wilds exactly where they multiply the best symbol on multiple lines.
There is no progressive jackpot and no multi stage bonus to create a separate prize pool. All of the potential is baked into the line pays and the way wilds stack into those lines. That makes the 3,000x number more of a long tail top end than a headline jackpot. It is reachable in theory on any spin, but the pay table is not engineered for frequent massive spikes.
With medium volatility and a single feature, most sessions will live in the zone of regular small hits, occasional scatter pays, and periodic Butterfly Feature outcomes that land in the low to mid hundreds of times bet. The huge hits are rare events, not a regular part of the experience.
How It Feels at the Spin Button
Butterflies II presents a bright, storybook garden with clear, cartoon style symbols. WGS put real effort into the facelift compared with its older catalogue. The reels are easy to read, the payline markers are unobtrusive, and the control panel uses the usual coin and line selectors that long time online players are used to.
Spin pacing is steady, neither particularly fast nor slow. The game does not pause for long animations outside of the Butterfly Feature. When the House symbol lands on reel 1 the screen holds for a short sequence as the butterfly leaves the house and lands on random positions. The animation is brief and does not drag, which keeps the feature feeling like part of the main spin rather than a separate game.
Audio is light and inoffensive, with simple reel sounds and a small flourish when the Butterfly Feature triggers. There is no heavy soundtrack loop, which suits players who prefer to keep sound on without fatigue over longer sessions. The user interface is functional, with clear bet displays and a visible win field that makes it easy to see how much the Butterfly Feature added on top of the initial line hit.
The Veteran's Verdict
Butterflies II is a straight lined, medium volatility slot built for players who like simple rules and do not need a feature map to understand what is going on. The math is honest about that. There is one real feature, and it lives entirely on reel 1 with the Butterfly House.
Players who enjoy long, low stress sessions on 25 line games will find a comfortable home here. The mix of line pays, scatter pays, and the occasional Butterfly Feature keeps the credit meter moving without the extreme droughts seen in high volatility modern titles. The trade off is a lack of depth. There are no free spins, no pick bonuses, and no progressive chase. Anyone who wants layered mechanics or bonus choice will likely find Butterflies II flat after a short time.
For bankroll planning, this slot suits medium length sessions at modest stakes. The absence of big, rare bonus rounds means the game does not demand deep pockets to weather long dry stretches. At the same time the 3,000x ceiling and the way the Butterfly Feature can spike a screen with wilds give it enough punch to keep outcome focused players interested.
Players who like clear, old school video slot math with a single, visible feature trigger will appreciate what WGS built here. Those who expect scatters to open free spins or who want modern high volatility swings are better served by more feature rich games in other catalogues.
✓ Pros
- •Simple 5x3, 25 line structure that is easy to understand
- •Butterfly Feature gives visible, on reel wild upgrades without complex rules
- •Medium volatility suits modest bankrolls and longer sessions
- •Scatter pays add extra value without needing paylines
- •Modernised graphics compared with older WGS titles
✗ Cons
- •No free spins or separate bonus round despite having scatters
- •RTP is not transparently published by the developer
- •Feature depth is shallow and can feel repetitive over time
- •Max win potential is capped relative to modern high volatility games
Bottom Line
Butterflies II is a straightforward WGS line slot that trades modern feature stacks for a single, easy to read mechanic. The Butterfly House on reel 1 does the heavy lifting. When it lands, the butterfly converts random positions to wilds and the game re evaluates wins, which is where the better outcomes live.
For players who prefer simple math, medium volatility, and a clear understanding of how wins are built, this is a respectable choice. Those who expect scatters to trigger free spins or who want layered bonuses and extreme volatility will likely move on quickly. The game respects players by keeping the rules transparent. It just does not offer much beyond that one signature move.
