    ⚠️ This bonus has negative expected value. The wagering requirement is too high relative to the game RTP. You'd likely lose R1400 more than the bonus is worth.

    How the Bonus Value Calculator Works

    The calculator estimates how much of a casino bonus you'll retain after meeting wagering requirements. It uses the formula: Expected Value = Bonus Amount − (Total Wagering × House Edge).

    For example, a R1,000 bonus with 30x wagering on slots with 96% RTP: Total wagering = R30,000. Expected loss = R30,000 × 4% = R1,200. Expected value = R1,000 − R1,200 = −R200. This bonus is slightly negative EV.

    To improve your expected value, play games with higher RTP (like blackjack at 99% where permitted), or look for bonuses with lower wagering requirements. Anything under 25x is generally good value.
