Rollbit runs a zero-rollover welcome offer, which is rare in the category. Winnings from the bonus credit as cash on the first qualifying bet rather than after multiple replays.
What to check in the current Rollbit T&Cs before opting in: the maximum bet size during wagering (usually $2 to $5), the time limit on completing the rollover (often 30 days), the game contribution rates, and whether any games are excluded entirely. Breaching any of those clauses voids the bonus and any winnings derived from it.
The full expected-value calculation, including realistic completion probabilities by game type, is on the Rollbit bonuses page.
Score breakdown across seven categories, deposit-tested screenshots, payout times we actually measured, and the bits the operator does not mention in their welcome banner.
