Frequently Asked Questions
What is GAIN.GG?
GAIN.GG is a simple GPT (Get Paid To) site. GPT sites allow you to earn rewards by completing tasks. These tasks can be taking surveys, watching videos, downloading apps, and much more.
Do I need to spend money?
You don't. Coins can be obtained by completing offers, and most offers do not require purchases.
What are coins?
Coins are the virtual currency used to represent your balance on the site. You can exchange these coins for a variety of rewards shown on our Withdraw page.
Every 1,000 coins is worth $1.00 USD.
How do I get started?
To get started, simply sign up using your preferred login method. We currently offer Google and Steam sign-in.
Once you're logged in, navigate to the Earn page – where you will see our range of offer walls.
How do I earn coins?
You can earn coins by completing offers on our Earn page.
Click on one of our available offer walls to see a list of offers you can complete. Each offer will show a short description and the amount of coins awarded for completing the task. Make sure to complete everything mentioned in the description.
Most offers will award coins within 5 minutes, unless otherwise mentioned, however in rare cases offer credits can be delayed by up to 48 hours.
How long does it take to receive rewards?
It may take up to 3 hours for unverified accounts to receive their rewards. Verified accounts are eligible to receive instant withdrawals.
Our staff will automatically verify an account after it has completed a minimum of 50,000 coins ($50.00) worth of offers. This amount is a minimum - accounts will not become automatically verified at this stage, and staff members review accounts after each withdrawal to check if the account should be verified.
Please do not contact staff about verification unless you have earned a minimum of $100.00. We offer 'balance allowances' before this stage, which allows you to receive insant withdrawals until you have withdrawn a certain amount, which you may request in support chat.
Why are my coins pending?
In order to combat fraud, our staff manually review certain high value offers. In some cases, such as if the offer requires payment, we may require additional proof of completion before awarding your points.
Most users can expect to receive their points within 24 hours, but we reserve the right to hold these high value offers for up to 90 days after completion if we believe the offer may have been completed fraudulently.
Why have I not received my coins?
In order to combat fraud, our staff manually review certain high value offers. To see if your offer is pending verification, click on your Profile and then click on the Held Offers tab.
If the offer is not pending our verification, you must contact the offer wall provider you used to complete the task.
Our staff here at GAIN.GG cannot investigate why an offer has not credited properly. You must contact the offer wall providers directly to receive compensation.

Is the roulette game fair?
Yes, the roulette game is provably fair, and uses a SHA-256 hash to prove that the round result was determined before the round started and before any bets were placed. SHA-256 hashing is used in the Bitcoin blockchain which is what the security of the network is built on.
To verify the round you're playing is legit, first take note of the hash before you place your bet. After the round has ended, the salt is revealed, which consists of 20 hex digits. This is then appended to the round result, separated by a '-' symbol, which is then hashed. If the result digit prepended to the salt is the actual game result, and the hash value you get by simply hashing the *result*-*salt* string matches the hash that you saw before the round started, then the game result is proven to be fair.
We understand that the above may not make sense unless you are somewhat familiar with basic cryptography. In more basic terms it means if we wanted to successfully change a round result and for the hash to match, we'd have to make two strings hash to the same thing, which has never been done by anyone in history. The probability of two hashes colliding is about 4.3*10^-60.
For the actual results themselves, we don't use any services like random.org to show true randomness. The reason for this is there would be no incentive for us to not make the results random, for example making green show up less often would only serve to decrease our house edge, and making green come up more often would allow users to bet on green and potentially make positive expected value bets.
Since there are 15 squares, the chances of hitting red or black are ~46.66%, and the chances of hitting green are ~6.66%. This means the house edge is 1/15 = ~6.66%.
