Short answer. Every bonus rule set we read reserves the right to void bonus winnings, confiscate the bonus and sometimes close the account for "abuse", and most name the behaviours. The recurring list: betting both sides of an even-money market (red and black, player and banker), hedging across accounts or sites, bonus stacking, multiple accounts, parking unsettled bets until wagering is done, delaying bonus rounds, arbitrage or matched betting, using VPNs to reach a restricted country, and bots. This page quotes the clauses so you can keep your play inside them. It does not describe ways around them.

How detection works, per the terms
Stake (5g) and Sportsbet.io (2.1.19) state they examine device properties, geo-location and IP masking, transactions and blockchain analysis. BC.Game lists device fingerprints, IP history, wallet ownership and payment instruments among linked-account factors (8.3). BitStarz audits every withdrawal (3.14). Expect the review to happen at withdrawal, after you have met the requirement.
Staying inside the rules
- One account, your own identity and payment methods, no VPN into a restricted country.
- Bet one side of a market at a time; no opposite or covering bets while a bonus is active.
- Finish bonus rounds and settle bets before the requirement completes; do not park them.
- One bonus at a time where the terms say so (BitStarz 3.12.1); do not combine offers.
- Stay under the max bet and inside the eligible game list.
- Keep bets ordinary in size and pattern; several brands flag sudden stake changes around completion as "patterns designed to clear with little risk".
FAQ
Can a casino void my winnings for bonus abuse? Yes; every term set above allows it, and several also allow deposit confiscation for connected-account fraud (Duelbits) or account closure.
Is betting red and black at the same time allowed with a bonus? BitStarz says such bets do not count; Shuffle and Cloudbet treat guaranteed-outcome betting as abuse. Avoid it.
Is using a VPN bonus abuse? It is a breach of terms at Stake, Pin-Up, Roobet, Duelbits, Rollbit and Sportsbet.io when used to reach a restricted jurisdiction; BC.Game allows VPNs except for that purpose.
