Expanding symbol · 5,000x
Greentube's upgraded Egyptian legend — hunt the Book to unlock expanding-symbol free spins.
Book of Ra Deluxe is the definitive Egyptian adventure slot from Greentube, the online arm of Novomatic. Launched in 2008 as the enhanced sequel to the 2005 original, it put the ‘expanding special symbol’ free-spins mechanic on the map — a formula copied across the industry ever since. You play a fedora-wearing explorer digging through a pharaoh's tomb across 5 reels, 3 rows and 10 adjustable paylines.
It is still a high-volatility favourite: wins can be scarce, but the free-spins round can pay up to 5,000x your stake at a 95.10% RTP.
Choose how many of the 10 paylines to play and set your stake (roughly 0.40 to 100), then spin. The golden Book is both wild and scatter: it substitutes for every regular symbol and, when three or more land anywhere, it triggers the Free Games round.
You get 10 free spins, and before they start one regular symbol is chosen at random to become the expanding special symbol. Whenever it appears it stretches to fill its entire reel and pays on any position — the moment the biggest wins happen. Any base-game win can also be sent to the optional Gamble feature to double it on a card-colour guess.
In the 10 free spins, one random symbol expands to fill whole reels and pays anywhere — the source of the 5,000x top win.
The Book substitutes for all regular symbols and triggers the free spins when three or more land.
Double any base-game win by correctly calling the colour of a face-down card.
Long dry spells are normal, offset by explosive free-spins potential and a 5,000x ceiling.
A certified, consistent return across 5 reels and 10 adjustable paylines.
The Explorer is the top symbol, followed by the golden idol, scarab and the Egyptian letters and numbers. The Explorer is also the symbol you want as your expanding pick: fill all five reels with expanded Explorers and you hit the 5,000x maximum. The Book's dual wild/scatter role keeps the base game ticking while you wait for the feature.
The blueprint that every ‘book’ slot copies, and still one of the best. Simple mechanics, iconic feel and a genuinely thrilling free-spins round — just come prepared for the high volatility.
