Bet365 – Halloween Warm-up
Players can expect some spooktacular prize potential of up to £1000 from bet365‘s special Halloween warm-up. This is essentially a prize draw, where every £10 staked (pardon the pun) on selected slots earns you a ticket for the draw. This eerie offer period runs from the 21st of October until the 27th and includes a range of epic Halloween games to try.
Mr Vegas – Step into the Alchemist’s Lab
Starting from the 28th of October until the 3rd of November, players at Mr Vegas can enter the Halloween alchemist’s laboratory. If you love a puzzle, this is the offer for you.
Each day, clues will be provided to help you guess the game of the day, including hints about the game provider. All you need to do is solve the clues and complete the daily task listed in the table to earn a spin on the Halloween Wheel of Vegas. The daily task must be completed by 23:59 GMT each day. We love how Mr Vegas has designed this promo, super creative indeed.
