On a phone, open the cashier and find the coupon field before you confirm the deposit. Springbok and White Lotus both want the code entered first. A deposit that goes through without the code usually stays as cash.
Springbok's mobile copy says bonuses and tournaments accepted on desktop apply on mobile and the other way around, because there is one account. The wagering games, the 30× deposit-plus-bonus rule and the R100 maximum bet are account rules, not desktop rules. Playing on a phone does not raise the maximum bet.
Gbets, Hollywoodbets, Apollo, White Lotus and Silversands all run website cashiers. Enter the same codes listed on the code page, then check that the bonus wallet shows the amount you expected before you stake.
Screenshots of a banner are weaker evidence than the cashier. If the banner says one cap and the cashier says another, the cashier is the offer you are funding.
Questions on this page
Does Springbok's bonus work on mobile?
Springbok's own mobile page says a bonus accepted on one platform applies on the other, and that you have one account. The coupon is still entered in the cashier.
Do I need an app to take these offers?
No. The coupons are cashier codes on the website. Apollo, White Lotus and Silversands also offer a software download. The promotion text is on their websites.
