William Hill Casino is offering a new promotion that pays players to try their hand at winning the now enormous Beach Life progressive slot jackpot.

As if taking home the £3.7 million jackpot wasn't enough, William Hill Casino is giving players cashback when they wager on the progressive slot and lose. The premise is simple: bet £5, and if you don't get paid by the machine, your bet will be refunded to your player account by the casino.

The cashback William Hill Casino promotion lasts all week. Refunded wagers will appear in player accounts on Sunday.

The Beach Life progressive jackpot can be played at all Playtech casinos. To win, players must wager the maximum bet on all paylines and activate the game's bonus feature by hitting three or more treasure chest symbols on one active payline. From here, they must align five sun symbols on the 20th payline.
