Rise of Ra is Amusnet's most-played game with an actual bonus round, and it is the only title in our coverage of this studio where the studio publishes its own volatility rating on a numeric scale.

A rare piece of first-party data

Amusnet rates its games out of five for volatility. Rise of Ra is a 4.

That is more useful than any "medium-high" label, and it is worth flagging because most studios do not publish anything comparable — PG Soft classifies its entire catalogue as "medium" regardless of structure, which carries no information at all.

A 4 out of 5 from the developer, on a catalogue otherwise full of low-variance fruit machines, tells you this game behaves differently from everything around it.

The free spins are the game

Three scatters award 15 free spins with a 3x multiplier applied to wins, and the round retriggers.

Two things follow.

A flat 3x across the whole round is a different structure from the accumulating or randomly-assigned multipliers used in modern releases. Every win in the round is worth exactly three times its base value — predictable, and it makes the round's outcome depend entirely on what the reels do rather than on a second multiplier lottery.

The retriggers are the tail. Players report rounds running to very large spin counts. Fifteen spins at 3x is a solid but ordinary result; the same round retriggered repeatedly is where the game's reputation comes from, and where its 4/5 volatility rating originates.

The wild doubles

The scarab beetle is the wild, and a wild participating in a winning line doubles that win. Combined with the free spins multiplier, a wild-assisted win inside the bonus is worth 6x its base value.

That stacking — 2x from the wild, 3x from the round — is the game's compounding mechanism, and it is the only one it has.

The progressive on five wilds

Distinct from the Jackpot Cards system, Rise of Ra carries a progressive jackpot that pays on five wild symbols on a payline, with a larger award if it lands during free spins.

That is unusual. Most progressives trigger randomly or through a dedicated bonus; this one is tied to a specific reel outcome, which means it is at least in principle visible on the paytable rather than being a black box.

The maximum win claim

Some sources state 10,000x. We would treat that cautiously.

A 15-line 5x3 game whose only compounding is a 2x wild and a 3x round multiplier does not naturally reach five figures without extreme retrigger sequences. The figure may describe a theoretical retrigger chain rather than a realistic outcome. It also sits alongside a separately-quoted progressive jackpot, and the two may have been conflated somewhere in the chain of sources.

Stakes

Reported as five fixed bet options ranging from 15 to 300 credits. Fixed bet steps rather than a continuous range is another land-based cabinet convention carried into the online build.

Who it suits

Someone who wants a genuine bonus round from a studio that mostly does not build them, and who can tolerate a variance profile the developer itself rates at 4 out of 5.

It does not suit anyone expecting the gentle grind of the studio's fruit machines. This is a different kind of game wearing the same brand.
