The EV calculator is a simple piece of software which can work out the estimated value on offers with 0x or 1x wagering. This is most likely to be free spins winning, wagering your initial deposit or a bonus that the bookmaker has credited to your account. 

It is fairly common for casinos to send out invite only offers to account holders so there may be times when you wish to check the value of an offer you have received. Once you have entered all of the details of the offer the EV calculator works out whether the offer is worth completing. 

For more complicated casino offers with higher wagering requirements or other complex terms you can use the Simulator software. The Simulator can simulate an offer a large number of times to get an accurate EV for that offer over the long term:
