Short version: rakeback pays you a share of the casino’s house edge based on how much you wager, win or lose. Cashback and lossback pay a percentage of your net losses, so they pay nothing when you are ahead. Terminology varies by site, so always read the terms. At Duel, rakeback is instant and covers 50% of the house edge on slots and other games that carry an edge (60% on Duel Blackjack), with no wagering requirement. Duel’s Originals use Zero Edge instead (100% RTP inside a $50,000 wagered a day, $1,000 max bet daily allowance). Worked examples and a calculator are below, and the full offer is on our bonuses and rakeback page.
Rakeback vs Cashback vs Lossback at a Glance
| Rakeback | Cashback | Lossback | |
|---|---|---|---|
| Based on | Amount wagered and the game’s house edge | Net losses over a period | Net losses, often in a promotion window |
| Pays when you win? | Yes, it is earned by wagering | No, only when you finish behind | No, only when you finish behind |
| Typical timing | Instant, daily or weekly depending on the site | Weekly or monthly | After the promotion period |
| Typical form | Real balance at Duel; elsewhere often tiered with levels | Real balance or bonus funds | Often bonus funds with wagering terms |
| Main catch | Check the rate and which games count | A “percentage of losses” sounds bigger than it is | Wagering requirements and caps on the bonus form |
Terminology is not standardised. One site’s “cashback” is another’s “lossback”, so judge each offer by what it is calculated on and how it is paid.
Worked Example: $10,000 on a 4% Edge Slot
Take a slot with a 4% house edge and $10,000 wagered. The expected loss is $400. These three offers, applied to four possible session results, return very different amounts:
| Session result | Rakeback at 50% of the edge | 10% cashback on net losses | Why it differs |
|---|---|---|---|
| Net loss of $1,000 | $200 | $100 | Cashback is bigger only when you lose a lot |
| Net loss of $400 (the average) | $200 | $40 | Rakeback pays 5 times as much at the expected result |
| Break even | $200 | $0 | Cashback pays nothing when you are not behind |
| Net win of $600 | $200 | $0 | Rakeback still pays on the wagering |
Rakeback is calculated on the edge you paid, so it does not depend on the outcome. Cashback only rewards a bad result.
The reason rakeback usually looks better on paper is that it pays on the average case, while cashback pays only on the unlucky tail. Cashback can still be worth having if the percentage is high and the terms are clean, but compare it with rakeback on expected value, not on how generous the headline sounds.

How Duel’s Rakeback Works
Duel pays 50% of the house edge back instantly on slots and other games that carry an edge, and 60% on Duel Blackjack. It is credited as you play, withdrawable, and has no wagering requirement. For example, take a slot with a 4% edge: you lose 4 per 100 wagered on average, Duel returns 2, and the effective edge halves to 2%.
Originals are different. Dice, Crash, Plinko, Mines and Blackjack carry a base 0.1% edge, and inside the daily Zero Edge allowance ($50,000 wagered a day, $1,000 max bet) an instant 0.1% rebate brings the net edge to zero. Once the allowance is used the rebate pauses until the reset. See the RTP guide and the Zero Edge page for the full picture, and our no-wagering guide for why there are no playthrough terms to clear.
How to Compare Any Rewards Offer
- Find what the offer is calculated on: wagers and edge (rakeback) or net losses (cashback and lossback).
- Check how and when it pays: instantly to a withdrawable balance, or later as bonus funds.
- Look for wagering requirements and caps on the paid amount.
- Check which games count and at what rate. Rates often differ by game type.
- Compare on expected value using the worked example, not on the headline percentage.

Niko’s Degen Take: Cashback Is a Marketing Trick
Degen take
Cashback marketing is built to feel generous while paying you mostly when you are already down. Rakeback pays on the edge you already paid, win or lose, which is why the worked example makes cashback look sad. When a site flashes 20% cashback at you, ask 20% of what, paid when and with what rollover?
Put your numbers in the calculator, it takes thirty seconds. I lean toward Duel’s setup because instant and withdrawable beats weekly and wagered, but check it against your own volume before you believe me.

Rakeback returns a share of the house edge based on how much you wager, whether you win or lose. Cashback returns a percentage of your net losses, so it pays nothing if you finish ahead.
At the expected result, usually yes, because rakeback pays on the edge you paid rather than only on a bad outcome. Cashback can win if you lose heavily and the percentage is high with clean terms. Compare both on expected value.
Lossback usually means a percentage of net losses returned during a promotion period, often as bonus funds with wagering terms. The word is used loosely, so read the terms on each site.
50% of the house edge on slots and other games that carry an edge, and 60% on Duel Blackjack, paid instantly with no wagering requirement. Originals use Zero Edge instead.
No. It is credited instantly as you play and is withdrawable, which is why Duel has no welcome bonus to wager through. See our promo code guide.
Multiply your total wagered by the game’s house edge to get the expected loss, then by the rakeback rate. For $10,000 on a 4% edge slot at 50%, that is $400 × 50% = $200. Our calculator on this page does it for any numbers.
