Mechanisms differ so players are able to claim deposit match bonuses and cashbacks, participate in competitions and raffles, and exchange accumulated loyalty points for real or bonus cash.
In addition to freebies offered to new members, all gaming sites present one or more ongoing and/or time-limited promotions created for those that are no longer newbies. No money will change hands even if you win unless the wagering requirement is met only then will the operator approve your payout request and release the funds. Having obtained a balance boost, you can pick one of the featured Roulette variants and start placing bets. An online casino might welcome you with a no-deposit bonus claimable as soon as you open an account but such propositions are nowhere near as common as welcome bonuses available only with the initial (or the first few) deposits. Roulette bonuses that will fit your needs the best are linked either to RNG table games or Live Roulette tables, though there’s nothing to stop you from claiming standard sign-up offers and various ongoing deals as long as you’re aware that as little as 10% or 20% of bets placed on your favourite game counts towards the rollover requirement.
