How It Plays
this slot runs on a 5×3 grid with 10 fixed paylines. Bet range is 0.02 to 20 per spin. The game is straightforward – land matching symbols left to right, collect the payout. Hit frequency sits at 30%, so you’ll see wins roughly one in three spins on average, though most are small.
The real engine is the free spins feature. Land 3 or more Book of Ra scatters anywhere on the reels, and you unlock 10 free spins with a 2x multiplier applied to every win. Before the round starts, one symbol is chosen at random to become the expanding symbol – it can stretch across up to 3 vertical positions on a single reel, stacking wins. Land that symbol multiple times and the payouts compound fast. You can also retrigger more free spins by hitting scatters again during the bonus round.

RTP / Volatility
RTP is 95.1% – a solid jump from the original game’s 92.13%. Volatility is HIGH, meaning payouts are clustered: long dry spells punctuated by chunky bonus hits. The max win is 10035x your bet, which is substantial for a high-variance slot but not extreme. Minimum bet of 0.02 keeps the game accessible; maximum bet of 20 suits bigger stakers.
Free Spins / Expanding Symbols
Trigger: 3 or more scatters land on any reel.
Award: 10 free spins with 2x multiplier.
Mechanic: One symbol expands to fill up to 3 positions vertically. If you land that symbol on multiple reels in a single spin, the expanded stacks can combine for significant payouts. Retrigger by landing more scatters – the bonus can stretch if the expanding symbol keeps landing.
This is where the slot grows teeth. Base game can feel flat, but the bonus round is where the expanding symbol mechanic does the heavy lifting. A lucky spin with multiple expanded symbols stacking across reels 2-4 can push you toward that 10035x ceiling fast.
Risk Game
Any win can be gambled in a 50/50 double-or-nothing game. Click the gamble button and choose your side – win and your payout doubles, lose and it vanishes. High-risk, high-reward friction. Skip it if you want to bank smaller wins; lean into it if the bonus just landed and you’re chasing the max.
Theme / Design
Ancient Egypt setting with Pharaoh treasures and hieroglyphic symbols. The Deluxe version upgraded the graphics and soundtrack from the original – it has a brick-and-mortar casino feel rather than a slick web design. Simplicity is the strength here: no flashy animations or cluttered feature menus. The game is easy to read and plays the same on mobile, tablet, or desktop.
