Book of Ra 6 Deluxe adds a sixth reel and the Extra Bet feature to the classic formula. The max win triples from 5,000× to 15,000×, but activating the sixth reel doubles the stake.

Book of Ra Deluxe uses a 5×3 grid with 10 paylines. Book of Ra 6 Deluxe offers the same 5-reel base layout but includes an optional sixth reel activated by the Extra Bet. With Extra Bet enabled, 6-of-a-kind combinations become possible. The payline count remains at 10 in both versions, but the sixth reel significantly changes the paytable values for premium symbols.

The 5-reel version defaults to 95.10% RTP. The 6-reel version has a default RTP of 95.03% without Extra Bet, rising to 96.06% with Extra Bet activated. Both carry high volatility. The key tradeoff: the 6-reel version offers higher theoretical returns with Extra Bet, but the doubled stake per spin increases bankroll pressure. A $1 base bet becomes $2 per spin with Extra Bet.

The 5-reel Deluxe caps at 5,000× total bet. The 6-reel version reaches 15,000× with Extra Bet active. The difference comes from 6-of-a-kind symbol payouts. The Explorer pays 500× per line for 5-of-a-kind and 1,500× for 6-of-a-kind. With the expanding symbol on all six reels during free spins, all 10 paylines pay the 1,500× rate simultaneously.

The 5-reel Deluxe suits players who prefer lower per-spin cost and consistent mechanics. The 6-reel version targets players comfortable with doubled stakes for tripled maximum win potential. For a bankroll of $200 at $1 base bet, the 5-reel version provides roughly 200 spins of runway. The same bankroll on the 6-reel version with Extra Bet provides only 100 spins — cutting the chance of reaching a bonus round nearly in half.
