Online Scratch Cards Guide
Online scratch cards are instant-win games: you buy a card, reveal hidden symbols by “scratching” with the mouse or a tap, and win if the symbols match a prize rule shown on the card. The outcome is decided by a random number generator the moment you buy the card; scratching only reveals it. In casinos they sit alongside pokies and other instant games, and several studios, most notably Hacksaw Gaming, which started out as a scratch card developer, publish dozens of titles.
How an Online Scratch Card Works
- Choose a card and a price. Online cards often let you choose the stake, from cents to tens of dollars. Prizes scale with the stake.
- Buy the card. The RNG determines the result immediately and the card is dealt.
- Reveal the panels. Scratch manually or use “reveal all”. The order of revealing has no effect.
- Collect any win. Wins are paid as a multiple of the card price, as shown in the paytable.
Common prize rules include “match three identical amounts and win that amount”, “match a winning number”, or “find a symbol to win the amount beneath it”. Some cards include multipliers or a mini bonus game.

Online Cards vs Paper Scratchies
Australians know scratch cards mainly as paper tickets sold through lottery outlets. The two products work differently:
| Feature | Paper scratchie (lottery) | Online casino scratch card |
|---|---|---|
| Result source | Printed in a finite print run | Random number generator per card |
| Prize pool | Fixed number of each prize across the whole run | Each card independent; fixed probability for each prize |
| Price | Fixed by ticket | Adjustable stake on most cards |
| Return disclosure | Odds of winning stated on the ticket or website | RTP and prize table in the game rules |
| Speed | One ticket at a time | Can be played in seconds, including autoplay |
With a paper series, prizes that have already been claimed change what is left in the pool. With an online card, every card has the same chances regardless of previous cards.
“Odds of Winning” vs RTP
Two numbers describe a scratch card, and they are easy to confuse:
- Odds of winning (hit rate): how often a card wins any prize, for example “1 in 3.5”. Many of these wins are small, often equal to or less than the card price.
- RTP (return to player): the share of all money staked that is paid back over the long run, for example 96%. The house edge is 100% minus the RTP.
A card can have a high hit rate and a low RTP, or the reverse. Example (illustrative prize table for a A$1 card):
| Prize | Probability | Contribution to RTP |
|---|---|---|
| A$1 (stake back) | 1 in 5 (20%) | 20.0% |
| A$2 | 1 in 10 (10%) | 20.0% |
| A$5 | 1 in 50 (2%) | 10.0% |
| A$20 | 1 in 200 (0.5%) | 10.0% |
| A$500 | 1 in 2,000 (0.05%) | 25.0% |
| A$5,000 | 1 in 500,000 | 1.0% |
| Total | Wins about 32.6% of cards | 86.0% RTP |
This card wins on roughly one card in three, but 20% of all cards only return the stake, and a quarter of the RTP comes from a prize that arrives once in 2,000 cards. In a typical session of 100 cards you would expect to get back noticeably less than 86%.
What to Check Before Buying
- The RTP in the game rules. Online casino scratch cards usually state it; compare it with the 95% to 97% typical of online pokies.
- The maximum win and whether it is a multiple of the stake.
- The prize table, to see how much of the RTP depends on rare top prizes.
- Autoplay settings. Instant cards can be bought very quickly; set a number of cards and a loss limit.
- Bonus terms. Scratch cards may count 100%, partially or not at all towards wagering, and some casinos exclude them.
Where to Play Online Scratch Cards
The casinos below accept Australian players and list Hacksaw Gaming, whose catalogue includes a large range of scratch cards alongside its slots. Search each lobby for “scratch” to see the current titles, and check each card’s RTP before playing.
Hacksaw’s slots, such as Wanted Dead or a Wild and Le Bandit, appear in the same lobbies; our profile of Hacksaw Gaming covers the studio.
Scratch Cards and Responsible Play
Scratch cards are quick, cheap per card and visually simple, which makes it easy to buy many in a row without noticing the total. A A$2 card bought every 10 seconds adds up to A$720 of stakes in an hour. Use the casino’s deposit and session limits, and see setting limits and reality checks for practical tools.

Frequently Asked Questions
Yes. The result of each card is set by a random number generator when you buy it. Scratching only reveals the result, so the order in which you scratch has no effect.
Compare it with online pokies, which typically return 95% to 97%. The RTP should be stated in the game rules; if it is not, check the prize table or choose another card.
It means about one card in three wins some prize. Many of those prizes only return the price of the card, so the hit rate says little about the RTP.
No. Paper scratchies come from a finite print run with a fixed number of prizes. Online cards are generated independently, each with the same chances.
It depends on the bonus terms. Some casinos count scratch cards fully towards wagering, others partly or not at all.
