Bonus spins on Book of Dead
No verified welcome spins sit on Book of Dead. Play'n GO titles are reported at Casumo, so a qualifying slot bet there can be placed on it where the lobby carries it. See free spins.
The UK version
Five thousand times a £5 stake is £25,000, or £10,000 at the £2 limit for under-25s. Autoplay is removed in the British version, so every spin is pressed by hand.
Verdict
High volatility in its purest form. The base game is thin; a premium expanding symbol is where the large wins come from.
