  • Until a reward is claimed.The guarantee ends once you approve a Robux reward. Rewards cost us money, so a family cannot take both.

Subscribing takes three steps

The account belongs to a parent or guardian. Children never register and never see a payment page.

  1. Choose a plan.

    Monthly with 15 extra days free, or yearly with one month free.

  2. Sign in with your email.

    We send you a link. There is no password to choose or forget.

  3. Enter your card.

    On Stripe's secure payment page, which shows the amount and the date before you confirm. Then add your child and play.

More questions? Questions parents ask. The full wording is in the terms.

Their next test is coming. Start practising tonight.
