The calculator
Wagering is capped at 10x in Britain. Averages assume stakes on games that count in full. A bonus can run out before wagering is complete.
Reading it
Stakes needed is bonus times requirement. Per day tests the deadline. Average value is the bonus less the long-run cost of clearing it.
