There are a few requirements you must meet to qualify for the referral reward:

1. Your friends should register within the 2 hours of clicking the link and then enter the game within that time period.
2. They must install the game from the specific megacool (mgcl.co) URL that you are sending them. If they install it any other way, it won't work.
3. They need to be new players. If they had the game installed on their device before, it won't count.

Your friends probably either didn't meet this requirement, used the wrong link, or accessed the link from their other device (i.e. they had to get the link on phone A, install the game on phone A, and do it within 2 hours of clicking the link on the same phone A).

Please try this step-by-step again with one of your friends, and if the counter has not increased, please contact us and include your friend's Player ID (looks like John#12345).
