Question: how many dollars are robux?
Answer: Although, much like Monopoly money, Robux don't have any real cash value in and of themselves. At any time during Roblox, you can visit the Buy Robux page to make a direct purchase. Spending $4.95 grants you 400 Robux (R$) and spending $9.95 grants you R$800. Naturally, the more you spend the better the value is.
