Quick Answer
In an online casino context, “playthrough” (also called wagering requirements or turnover) refers to the number of times you must bet your bonus amount (or sometimes your deposit plus bonus) before you can withdraw any winnings earned from that bonus. For example, a 30x playthrough on a $100 bonus means you must place $3,000 in total bets before cashing out. Australian players should know that under the Interactive Gambling Act 1997 (IGA), licensed offshore casinos offering bonuses to Australians operate in a legal grey area, and local laws prohibit unlicensed operators from targeting Australian residents. Always verify the terms before accepting any bonus.
Understanding Playthrough in Detail
Playthrough is a core mechanic used by online casinos to prevent bonus abuse and ensure the casino maintains a mathematical edge. Without it, players could simply claim a bonus, withdraw it immediately, and walk away. Here’s a breakdown of how it works:
How Playthrough Is Calculated
Most casinos define playthrough as a multiplier applied to either:
- Bonus amount only – e.g., 30x on a $100 bonus = $3,000 in bets.
- Deposit + bonus – e.g., 30x on ($100 deposit + $100 bonus) = 30 x $200 = $6,000 in bets.
- Winnings from free spins – e.g., 40x on any winnings from free spins.
Always check which calculation method applies, as a “deposit + bonus” requirement is effectively twice as expensive.
Example Scenario
You deposit $50 and receive a 100% match bonus ($50 extra) with a 35x playthrough on the bonus. You must bet 35 x $50 = $1,750 before withdrawing. If you win $200 during this period, those winnings remain locked until the $1,750 in bets is completed.
Game Contribution to Playthrough
Not all bets count equally toward playthrough. Casinos assign different contribution percentages based on game type:
- Slots – Typically 100% contribution (every $1 bet counts as $1).
- Table games (blackjack, roulette) – Often 10–20% or even 0%, because they have lower house edges.
- Video poker – Usually 10–20%.
- Live dealer games – Often 0–5%.
Important: If you play a game with low contribution, you may need to bet far more than expected to clear the playthrough. For example, a $1,000 requirement on blackjack at 10% contribution would require $10,000 in bets.
Common Playthrough Terms and Traps
- Max bet limit: Most bonuses cap your bet size (e.g., $5–$10 per spin/hand) while wagering is active. Exceeding this can void your bonus and winnings.
- Game restrictions: Some slots are excluded from playthrough (e.g., high-RTP games like Blood Suckers or progressive jackpots).
- Time limits: You must complete playthrough within a set period (e.g., 7–30 days). Failure means forfeiting the bonus and any winnings.
- Maximum cashout: Even after meeting playthrough, some casinos cap how much you can withdraw from bonus winnings (e.g., 10x the bonus amount).
Australian Legal Context: The IGA 1997
The Interactive Gambling Act 1997 (IGA) is Australia’s primary law governing online gambling. Key points relevant to playthrough and bonuses:
- Prohibition on “in-play” sports betting and unlicensed casino services: The IGA makes it illegal for operators to offer “real money” online casino games (slots, roulette, blackjack) to Australian residents unless they hold a valid Australian license. However, no Australian state or territory has issued such licenses for online casinos—only for sports betting and lottery.
- Offshore casinos: Many overseas-licensed casinos (e.g., Malta, Curacao) accept Australian players despite the IGA. The law targets the provider, not the player, meaning you are not breaking the law by playing, but the casino may be. The Australian Communications and Media Authority (ACMA) blocks unlicensed sites and issues warnings.
- Bonus legality: The IGA does not specifically regulate bonus terms like playthrough. However, Australian consumer law (Australian Consumer Law, ACL) prohibits misleading or deceptive conduct. If a casino’s playthrough terms are unclear or hidden, you may have legal recourse—though pursuing offshore operators can be difficult.
How to Evaluate Playthrough as an Australian Player
Before accepting any bonus, ask these questions:
- What is the playthrough multiplier? (Lower is better; 20–35x is common.)
- Is it on the bonus only or deposit + bonus? (Always prefer bonus-only.)
- Which games count at 100%? (Stick to slots if you want quick clearance.)
- Are there max bet or game restrictions? (Avoid if your preferred game is excluded.)
- What is the time limit? (7 days is tight; 30 days is more reasonable.)
- Is there a max cashout? (A cap of 10x bonus or less makes the bonus unattractive.)
Mathematical Reality: Why Playthrough Favors the Casino
Even with a generous bonus, playthrough often erodes your expected value. Consider a $100 bonus with 30x playthrough on slots (house edge ~5%):
- You must bet $3,000.
- Expected loss from betting = $3,000 x 5% = $150.
- Your bonus is $100, so your net expected outcome is -$50.
This means most players will lose their deposit and bonus before meeting playthrough. Only if you get lucky (or choose games with very low house edge) can you profit. Australian players should treat bonuses as entertainment, not guaranteed profit.
Key Takeaways for Australian Players
- Playthrough is a wagering requirement that locks your bonus and winnings until you bet a specified amount—always read the full terms.
- Australian law (IGA 1997) prohibits unlicensed online casinos from targeting you, but you are not personally penalized for playing. Stick to reputable offshore operators that are transparent about terms.
- Game contribution matters: Slots are best for clearing playthrough; table games are often poor value due to low contribution rates.
- Watch for traps: Max bet limits, time constraints, and max cashout caps can make bonuses worthless. Calculate the expected value before playing.
- No Australian-licensed online casinos exist for slots or table games, so all bonuses you encounter are from offshore sites—verify their licensing and reputation independently.
- Always prioritise responsible gambling: Never chase playthrough with funds you cannot afford to lose. Set deposit limits and time reminders.
