A promotion is worth exactly what its terms allow you to keep, and the headline number is rarely the part that decides it.
That is the first thing to check in any offer, here or anywhere else. Winnings you can withdraw straight away are worth what they say; anything held behind a turnover requirement is worth only part of that until the requirement is cleared. How realistic it is to clear the terms comes down to the remaining lines: the expiry window, the minimum odds per ticket, and each game's share of the turnover.
For today's amounts and deadlines, check the promotions page, because no campaign runs forever. The guides below cover how to read an offer, not what happens to be live.
