I doubt anyone will go for the full £50, but the first £15 free bet is fairly straightforward.
Open an account with 888sport and place a bet of at least £15 and 888sport will then credit your 888sport account with a £15 free bet token.
This is where it gets a little bit costly: Place a further 9 bets of at least £15 each, and you will qualify for a second 'bet bonus' free bet token of £15. Place a further 5 bets of at least £15 each, and you will qualify for a yet another 'bet bonus' free bet token of £20. Only bets of at least £15 each will count towards your next free bet (bets of a lower value do not affect your entitlement to the offer).
Obviously most people won't want to take up the second offer, but it's not bad if you are prepared to gamble the large sums of money (hey, some people do). For everyone else... the free £15 is pretty good.
How to redeem a free bet:
You can view any free bet tokens you have by clicking on My Account from the home page and selecting the Free Bets option.
To redeem a free bet, just make a bet selection the way you ordinarily would. The option to redeem a free bet token on that bet will appear at the bottom of your betslip. Simply mark the box that appears beside it, and select an outcome from the dropdown menu to the right.
T&Cs: Offer applies to new customers only. Existing or previous 888sport customers do not qualify. All qualifying bets must be a minimum of £15 and must be placed at odds of evens (2.00) or greater (for each-way bets total stake must be at least £30). Multiple bets count as one bet and all legs must be placed at odds of evens (2.0) or greater. Free bet stakes are not included in any returns. Free bet tokens must be used in their entirety on a single bet. They cannot be used to place a succession of smaller bets. If the odds of the selection on your first bet are less than evens (2.00) your next bet at evens (2.00) or greater will qualify for the free bet. Non-runners do not count as qualifying bets. Duplicate bets on the same selection in the same event do not count as qualifying bets. Free bet tokens can be used to place single bets only and expire after 30 days. The loyalty bonus promotion expires 90 days after the customers opening £15 or more bet. Offer is limited to 3 free bet tokens per person, per household, per computer, per e-mail address or per payment details. This offer cannot be used in conjunction with any other open account offer. 888sport offers are intended for recreational players and 888sport may limit the eligibility of customers to participate in any promotion. Free bet tokens must be used in accordance with 888sport's general terms and conditions. 888sports decision is final on all matters relating to the awarding of any bonus and shall not be subject to review or appeal by an entrant or any third party.
