666 Casino offers an enticing welcome bonus aligned with its devil-themed concept. The welcome package includes a match bonus of up to £66 across the first six deposits:

  • First deposit: 100% match bonus up to £66 and 66 free spins on the Book of Dead slot.
  • Second deposit onwards: 50% match bonus up to £66 (no free spins).

Upon a minimum deposit of £20 for the first time, players can unlock the welcome package. The maximum bonus bet allowed with bonus funds is £5 per game. Cash bonuses are valid for 30 days, while free spins on the Book of Dead slot expire after ten days. The maximum winnings from free spins are capped at £50.

To convert bonus funds to cash funds, players must fulfill a 35x wagering requirement, calculated based on the cash deposit plus bonus funds. Slot games contribute 100% to the wagering requirement, while other games, except for scratch cards and keno, do not contribute.
