Casino welcome offers look like gifts and behave like traps. Plug any bonus into the calculator below and get a 0–100 score based on realistic expected retention — not marketing spin.
Numbers update live.
The score uses a 4% house edge assumption on pokies, subtracts expected play-through loss from the bonus, applies max-cashout caps and deducts points for hostile terms (low max bet, short expiry, pokies-only). It's a quick sanity check — not financial advice. Always read the full T&C before accepting any bonus.
Because the wagering scales with them. A A$5,000 bonus at 40× play-through = A$200,000 in turnover. At a 4% house edge that's A$8,000 expected loss to clear — bigger than the bonus itself. Large headline numbers with ugly rollover are designed to look generous, not be generous.
Anything above 55 is worth considering. Above 70 is rare and usually either a small no-deposit free credit (3–5× rollover) or a deposit match below 30× on bonus-only. Be skeptical of anything scoring 85+ unless you've read the T&C twice.
No — spins vary too much by game selection, bet size and expiry to model cleanly. In practice, 50 spins worth ~A$10–15 expected value. Treat them as a small bonus on top of the score here.
Zero meaning no cap is the gold standard. Many offshore bonuses cap winnings at 5–10× deposit — a brutal nerf that invalidates big bonus wins. If max cashout is 5×, set it to 5 in the tool and watch the score drop.
Because you're forced into pure negative-EV games. All-games bonuses let you wager on low-edge tables like blackjack (0.5%) or video poker (0.3%) to clear the rollover cheaper, even after contribution weighting.
They score very well because wagering is only 3× on a small free credit. Even if they cap cashout at, say, A$500, the expected retention still easily beats a typical A$1,500 / 35× deposit match. That's why they appear near the top of our no-deposit guide.
