Scratch cards and instant win games are a common way to take part in games of chance. But knowing how to check if you’ve won—or what to do next—can be confusing, especially with so many types available in shops, online, and on apps.
This guide explains how scratch card checker tools work, how results are shown, and what you might expect when playing online or in person. It also covers the basics of Random Number Generators (RNGs), how to claim any potential prizes, and tips to help you better understand each step.
How Scratch Card Checkers Work
Scratch card checkers are tools designed to help you find out whether a ticket or game has resulted in a win. You’ll usually find these on websites, or physical scanning machines in shops.
In the UK, one of the most commonly used apps is the National Lottery app. This can only scan draw-based lottery tickets—such as the Lotto, EuroMillions, or Thunderball—to tell you if your ticket has won. It works by reading a barcode or QR code printed on the ticket. It cannot scan physical scratch cards, including the foil-panel ones sold in supermarkets, newsagents, or other retailers. Those cards need to be checked manually.
To check a traditional scratch card, you must first reveal the panel by scratching it. Then, follow the instructions printed on the card—usually by matching symbols, amounts, or numbers—to see if you’ve won. If you’re unsure, staff in-store can often scan the card using their lottery terminal.
If you're playing scratch cards or instant win games online, the result is shown on the screen. You won’t need to scan anything—the game outcome is revealed after you interact with the game (usually by tapping or clicking to uncover the results).
Keep in mind that different companies may offer their own types of scratch cards, each with their own systems and processes. There is no universal scratch card checker that works across all brands, since each provider sets up their cards and rules differently. It may be a good idea to read the specific instructions or terms before playing, especially if the game isn’t from the National Lottery.
Checking For A Win Online
Online scratch cards and instant win games work differently from the ones you buy in shops. When you play online, you don’t need to physically scratch a card. The process is digital. You either click a button or swipe a screen to reveal symbols, numbers, or game outcomes.
The result is usually shown almost immediately. If you’ve won, the amount is displayed on the screen. For most online games, the prize will be added to your account balance automatically. You won’t need to take any extra steps to claim any smaller potential wins.
All licensed online games in the UK use something called a Random Number Generator (RNG). This is a type of software that picks outcomes at random. It makes sure that each play is independent and cannot be predicted or influenced. These systems are tested and regulated to ensure fairness.
It’s worth noting that not all online games are called “scratch cards”. Some are labelled as “instant win games”. These can look and feel different, depending on the website or app you’re using, but the outcome is still based on chance.
You’ll usually find information about how the game works, including the prize structure and odds, somewhere on the site or in the app. This can help you understand what sort of outcomes are possible before you play.
Odds may vary. For example, some scratch cards may offer a 1 in 4.5 chance of winning any prize, but that does not mean you’ll win once every 4 or 5 plays. Each game is independent.
Can You Check Your Scratch Card In Shop?
If you’ve bought a scratch card in person, you can have it checked at the same shop or at another retailer that sells similar cards. Most shops that sell National Lottery scratch cards have a terminal that can scan the barcode hidden underneath the scratch-off panel. This scan will confirm whether the card has won or not.
For other scratch card providers—such as those offered by certain bookmakers, charity lotteries, or private gambling companies—shop processes can differ. Some retailers may not be able to check these in-store at all. In those cases, you’ll need to follow the instructions on the back of the card or visit the provider’s website.
If your scratch card has been damaged, or if the scratch panel is unreadable, the shop terminal won’t be able to scan it. Try to keep the card intact until it has been checked and claimed.
Shops can usually pay out smaller prizes straight away. For National Lottery scratch cards, many shops can usually pay prizes up to £100 in cash. Some may pay up to £500, but this depends on the retailer’s policy and how much cash they have available at the time.
Any prizes over this amount may require you to fill out a claim form or post the card to the provider. You may also need to show proof of ID or address, especially for larger amounts.
How To Claim Scratch Card Winnings
Claiming a prize depends on whether you played online or bought a scratch card in person, and on how much you’ve won.
If you bought your card in a shop and won up to £100, many retailers should be able to pay the prize in cash. Some may pay more—up to £500—but this varies. Prizes above that usually require a claim form and may need to be posted to the organisation that issued the card. Full details are usually printed on the back of the scratch card or found on the provider’s website.
For very large wins (such as over £50,000 from the National Lottery), you’ll usually need to make an appointment to claim in person. This is to carry out identity checks and confirm the details.
If your win came from an online game, the prize will normally appear in your account balance once the game ends. Before you can withdraw the funds, the gambling company may ask you to verify your identity. This is a legal requirement in the UK. It helps prevent fraud and ensures all players meet the minimum age of 18.
You may be asked for documents such as a passport, driving licence, or utility bill. The checks usually only need to be done once.
Each company will have their own process for handling claims, so it may be best to read their terms if you’re not sure. It’s also worth checking if there are any time limits for claiming a potential win.
Scratch cards and instant win games are random by nature. There is no skill involved in the outcome, and no method can change your chances after you’ve bought or entered a game. No strategy can guarantee a win.
If you decide to play, it helps to set a budget and stick to it. Only spend what you’re comfortable with, and avoid chasing losses. Many gambling websites and apps include features like deposit limits, time reminders, or account breaks—these tools are available if you ever feel you need them.
