Wings of Riches is a 5-reel, 3-row slot with 20 paylines, released by NetEnt in December 2019. It runs at 96.63% RTP with a volatility rating of 4.5 out of 10, sitting in low-medium territory. Hit frequency is a healthy 38%, the maximum payout caps at 800x your total stake, and bets range from 0.20 to 100 per spin. The butterfly theme is gentle and colourful, and the feature set follows suit - three clean mechanics that interact during Free Spins to create an escalating win potential that the base game only hints at.
NetEnt kept the design focused here. Rather than stacking half a dozen features on top of each other, Wings of Riches uses a Spreading Wild, a retrigger-capable Free Spins round, and an Increasing Multiplier that builds through the bonus. Each piece is simple on its own, but they combine to create Free Spins sessions where the final spins carry substantially more weight than the first.
Spreading Wild
In the base game, Wild symbols can initially appear on reels 2, 3 and 4. When a Wild lands, it may spread to reels 1 and 5 as well, extending its reach across the full grid. The spread is not guaranteed on every appearance - sometimes the Wild stays put on its original reel, other times it pushes outward to cover additional positions.
The mechanic works differently during Free Spins. Instead of landing organically and potentially spreading, one Wild symbol is randomly placed on the reels before each spin. This guaranteed Wild placement is a significant upgrade over the base game, where Wilds depend entirely on the reel draw. Every single Free Spin starts with at least one Wild already on the grid, giving each spin a head start toward forming winning combinations.
Spreading Wilds on the centre reels are the most valuable in the base game because they have the potential to bridge wins across all five reels simultaneously. A Wild on reel 3 that spreads both left and right covers reels 2 through 4 at minimum, and can extend to cover all five positions in a row.
Free Spins
Three or more Scatter symbols anywhere on the reels in the main game award 10 Free Spins. The feature can retrigger during play - landing two Scatters adds five extra Free Spins, while three Scatters add ten extra. There is no stated cap on retriggers, so the round can extend well beyond the initial ten spins if Scatters cooperate.
The retrigger threshold of just two Scatters for five additional spins is notably generous. Most NetEnt slots require three Scatters to extend a Free Spins round, so the two-Scatter option here effectively doubles the retrigger frequency. Combined with the guaranteed Wild placement each spin, the Free Spins round is where Wings of Riches does its real work.
Increasing Multiplier
The Increasing Multiplier is exclusive to Free Spins and is what gives the bonus round its escalating character. During the feature, a Multiplier symbol can randomly appear on reel 5. Each time it lands, the active win multiplier increases by one, starting from x1 and climbing to a maximum of x5.
The multiplier is cumulative and persists for the remainder of the Free Spins session. Once it ticks up, it stays at that level. If the Multiplier symbol lands on four separate spins throughout the round, the final multiplier reaches x5 and every subsequent win - including those boosted by the guaranteed Wild placement - gets multiplied accordingly.
The interaction between the Increasing Multiplier and the retrigger system is where the maths become interesting. A long Free Spins session that retriggers multiple times gives the Multiplier symbol more opportunities to appear, meaning extended rounds are disproportionately more valuable than short ones. A 30-spin Free Spins session with a x5 multiplier running for the final ten spins produces results far beyond what the base game can achieve.
Base Game Rhythm
Outside of the bonus features, Wings of Riches plays as a standard 20-line game with a high hit rate. The 38% frequency means you are landing wins on roughly two out of every five spins, which keeps the base game active and the balance relatively stable. Most of those wins will be small returns below your stake, but the Spreading Wild adds occasional spikes when it extends across multiple reels and completes several lines at once.
The base game serves primarily as the vehicle for reaching Free Spins, where the real earning potential sits. Three Scatters on a 5x3 grid with 20 lines is a reasonable ask, and the high hit frequency keeps you in the game long enough to get there without bleeding through your bankroll.
RTP, Volatility and Where It Fits
The 96.63% RTP is above average for NetEnt and for the industry generally. The 4.5 out of 10 volatility and 38% hit frequency reinforce the low-medium profile - this is a slot designed for sustained play rather than boom-or-bust sessions. The 800x maximum win reflects that positioning.
Wings of Riches sits in a similar bracket to Butterfly Staxx and Wilderland within NetEnt's catalogue - visually polished, mechanically restrained, and mathematically gentle. The butterfly and nature theme is executed with NetEnt's usual production quality. What sets it apart from its stablemates is the Increasing Multiplier, which gives Free Spins a clear escalation arc that many low-medium variance games lack. You are not just waiting for big symbol combinations - you are watching the multiplier build and hoping the round lasts long enough for it to reach its ceiling.
