Wings of Ra Slot Review: Mystery Coins Change the Reel Mix

Wings of Ra is a compact five-reel Egyptian slot whose Free Spins gradually alter the symbols available on the reels. Mystery Coins reveal one random symbol, and every coin landing in the bonus fills a 14-coin meter. Each completed meter converts the current lowest-paying symbol into another Mystery Coin, so progress changes the reel mix rather than simply adding a multiplier. That gradual removal is the central idea: coins can help clear low symbols, but their shared reveal means a spin’s coins are not independent selections.

Ten lines and a shared mystery result

The base layout is 5×3 with ten paylines, and wins pay on adjacent matching symbols. Mystery Coins can land and reveal a random symbol; all Mystery Coins on the same spin reveal the same symbol.

Three Free Spins symbols anywhere trigger twelve spins. Every qualifying scatter above the minimum adds three more, so a larger trigger starts with a longer round. Mystery Coins that land during Free Spins add to a special bar requiring fourteen coins per fill. When complete, the current lowest-paying symbol is transformed into a Mystery Coin; transformed symbols on the reels also count toward the overall progression. The bar can fill more than once, continuing until every symbol except the highest-paying one has been transformed.

How the bonus changes over time

Second, once a low-paying symbol has become a Mystery Coin, future coin reveals can no longer reveal that converted symbol. The pool of ordinary symbols therefore contracts as the bar advances, while transformed positions themselves contribute to later filling. This creates a compounding loop: a completed meter changes the board and can make subsequent progress easier to track, but it does not promise a particular high-paying reveal. Importantly, the conversion affects both the symbol set and the progress count: symbols changed on the reels also contribute to filling the bar. Once a symbol is converted, Mystery Coins can no longer reveal that symbol, so successive fills progressively narrow the ordinary reveal pool. This is the bonus’s lasting state change; it persists across its spins rather than applying only to the coin that completed the meter.

Nor does it publish symbol odds or explain whether every possible transformed position is equally likely to contribute. A long bonus can still spend many spins collecting coins before another conversion, and the shared random reveal can produce the same lower symbol across several coins in one spin.

Configuration and limits

The detailed record lists 95.69% RTP, volatility index 18.06, 5×3 reels, ten lines, 3,166x maximum payout and a release date of 27 February 2020. The official catalog describes volatility as high. The game supports stakes from 0.10 to 50, and no Feature Buy is listed. These figures apply to the standard record; no alternate RTP configuration is supplied in the official catalog for this title.

The feature’s strongest point is that each completed meter makes a lasting, visible change to the available symbol set, giving the bonus more direction than a simple collection counter. Its restriction is dependence on Mystery Coin landings: until the fourteen-coin threshold is reached, the board remains unchanged, and the shared reveal may not produce a useful symbol.

Strengths and weak points

Strengths

A 14-coin threshold produces a lasting, visible change by converting the lowest-paying symbol, so bonus progress has a concrete effect on later spins.

Weaknesses

Meter progress depends on Mystery Coin landings with undisclosed odds, and multiple coins share one random reveal per spin rather than independent results.

Our Editor’s View

Wings of Ra gives its Free Spins a defined progression: collect Mystery Coins, fill the meter, and remove the lowest-paying symbol from the ordinary pool. The conversion can repeat, while the revealed coins share a symbol on each spin, so the same mechanism carries both its upside and its constraint. That makes the bonus easy to explain and lets the board evolve in view, though the rate of change remains uncertain. The modest ten-line base layout keeps attention on the coin system, but the bonus still requires repeated collection before the symbol mix shifts. Players who prefer a feature with visible milestones may appreciate this gradual transformation, as long as they do not read the meter as a guarantee of premium-symbol wins.
