My favourite Book Of Ra win was in the land based one where I had lost about £1k in the arcade so was tilted and went to the casino, got a bonus on Ra £2 stake sigh 10s…only for the explorer line to smash in during the free spins! Shame I didn’t have you as the expanding symbol mate!
Used to get the 400x pharaoh line loads for some weird reason too
On another note I once had a full line of birds on Lady Luck £5 stake and thought TEN GRAND!!! Then it flashed up £2500 as it turned out the last bitch was one square out of place!
