01Opening the crypt
Three or more 
Tombs anywhere on the reels start the free spins. Reviews report a starting round of 8 to 10 spins; the game shows the exact number on the intro screen. Before the first spin, one regular symbol is chosen at random as the special expanding symbol.
02How a symbol expands
When the special symbol lands on enough reels to pay — two for the pictures, three for the cards — every one of those reels fills with it. It then pays as if it were on all ten lines. The reels don't have to be adjacent: reels 1, 3 and 5 count as three.
| Special symbol filling all 5 reels | Pays (× total bet) |
|---|---|
 Pharaoh | 5,000× |
 Anubis | 1,600× |
 Golden mask ·  Horus | 600× |
 A ·  K | 120× |
 Q ·  J ·  10 | 80× |
03Retriggers add symbols
Three or more Tombs during the free spins award extra spins and a new special symbol. From then on, every chosen symbol can expand on the same spin, and their wins are added together. Reviews put the limit at nine special symbols — one for each regular symbol.
04Wins that aren't expansions
Ordinary line wins still pay during the free spins, and the Tomb still acts as Wild. Expansion wins are added on top.
05Realistic expectations
Most rounds end with modest wins. The 5,000× top win needs the Pharaoh as the special symbol across all five reels — very rare. Treat the big numbers as possibilities, not targets.
