What does play through mean at online casino?

"Play through" means wagering requirement — the number of times you must bet your bonus amount before you can withdraw any winnings. For example, a $10 bonus with 30x play through requires you to place $300 in bets before cashing out.

• Wagering requirement: The multiplier applied to bonus amount. 35x means bet 35 times the bonus value.
• Bonus only vs Deposit + Bonus: Some casinos require wagering only on the bonus; others require wagering on both deposit and bonus. The latter is harder to clear.
• Game contribution: Not all games count 100% toward wagering. Slots usually 100%, table games often 10-20%, some games excluded entirely.
• Maximum bet limit: Usually $5-$10 per spin while wagering. Exceeding this can void your bonus.
• Expiry period: You must complete wagering within a time limit — typically 7-30 days.
• No wagering bonus: The holy grail — any winnings are withdrawable immediately with no play through required.
