The new cap reduces your total betting target by £750, making it significantly easier to clear the bonus safely within standard game stake limits. There are also typically time restrictions on how long you have to fulfil the qualifying requirements after registering and the time you have to use your bonus before it expires. In both instances, the longer the time, non-gamstop casinos the easier it is for players.
