How to capture and check big wins

Introduction

With a large win, it is important not to miss the moment and collect maximum evidence: technical, financial and communication. This allows you to make sure that the slot calculations are correct, eliminate possible errors and, if necessary, protect your rights through the support service or regulator. Below is a clear plan of action.

1. Record results immediately

1. Screenshots and videos

Take screenshots of the screen before and after winning: balance, bet, win, back ID (if displayed).
Record a short video (5-10 seconds) showing the animation of the win, the opening of the bonus round and the final balance.
Save files to the cloud (Dropbox/Google Drive) and locally with a time stamp.

2. Unloading logs

If the casino provides transaction history in your personal account, download CSV or PDF with a full log: time, bet, result of each spin.
For progressive networks, record the current value of the pool at the time of winning (screenshot of the progress bar or amount).

2. Spin fairness test

1. Back ID and RNG

Record the spin ID (if available) and note the UTC time.
Upon request to support, request a report on the generated RNG number for this spin and its verification by a third-party laboratory (eCOGRA/iTech Labs).

2. Reconciliation of RTP and Distribution

Compare the actual value of the win with the declared RTP report of the slot: make sure that the payout is within the statistics.
For bonus rounds, request a separate RTP report (if the slot supports Bonus Buy, Hold & Win) to see if there was an exception.

3. Financial documentation

1. Output transactions

In the first test output, save the transaction confirmation (screen or PDF from e-wallet/bank): amount, time, status "processed."
Keep receipts for each subsequent tranche as well.

2. Payment details

Record the details of the funds: wallet number, bank account. Keep this data protected.

3. Tax and legal documents

Save screenshots and statements for the declaration, even if single winnings are not taxed in your jurisdiction, in case of a professional game.

4. Communication with support

1. Ticketing

Open the ticket in the chat or by e-mail immediately after fixing: indicate the details of the win, attach screenshots and logs.
2. Case number

Save the ticket number and all correspondence; Copy all confirmation messages from the support.
3. Escalation

If the response is delayed or looks formal, request escalation to the manager or compliance department; Specify SLA dates (typically 24-48 hours).

5. Storage and security of evidence

1. Secure storage

Save copies in two clouds and on local media. Encrypt the folder with a password.
2. Audit and reserve

After a month, check file availability and integrity. Mark the check date.

6. Actions in dispute situations

1. Rejected cashout

Request a reason for refusal, attach evidence. If the decision is incorrect, contact the regulator (UKGC, MGA, Curacao) with copies of tickets and logs.
2. Delayed payments over SLAs

Remind about the license regulations, indicate the ticket number and require specific processing times.
3. Legal aid

If you refuse to pay more than €10,000, consult a gambling lawyer or use alternative arbitration (eCOGRA, IBAS).

Conclusion

A clear procedure for fixing and checking a large win is a guarantee that you will receive exactly the amount you deserve. Collect screenshots and logs, document transactions, interact with support and store all evidence. This will allow you to defend your rights and protect yourself from technical or bureaucratic failures.
