Smart plays to turn bonuses into cash
- Pick wagers with clear odds listings at -500 or longer so your bets count 100% toward playthrough.
- Avoid opposite-side hedges that negate contribution. If you aim to clear Onyx Cash fast, focus on straight moneyline, spread, totals, or single props that meet odds requirements.
- Keep an eye on the 60-day expiry for match bonuses and claimed Onyx Cash. Don’t let credits sit unused.
- Use the minimum deposit threshold ($10) to trigger promos without overspending; then scale up when you’ve met the playthrough.
