You can pay for premium games such as ACBL Speedballs, Instant Tournaments, Daylongs, etc. on BBO with BB$ (BBO dollars). BB$ are like pre-paid entry fees.
You can purchase BB$ with a credit card or paypal from https://www.bridgebase.com/bb$
You consume your BB$ as you pay for various games.
Mobile users ( phones, tablets ) can purchase BB$ via the link above or from the mobile app shop. Please note that the appstore prices are significantly higher than on the browser version.
Desktop users have access to a BB$ button when they login.
You can instruct BBO to keep your BB$ balance topped up when you purchase, by activating the “Auto-refill” feature. Then you never need to worry about “running out” of entries at an awkward moment.
If you get stuck, an email to email@example.com will loosen things up.
And that’s all there is to it.
