Rewards
Inviting friends: what works, and what we ask you not to do
The invite reward is there for people who bring in real friends. How to share your link in a way that works, and the few things that get accounts closed.
Share with people you know
The invites that work are personal: a message to a friend who you know enjoys a number game, a word with a colleague, a post to people who follow you because they are interested in what you share. Say plainly what fourdigits is and that it is for adults only.
Use the tools on the Invite screen
Your link, your code, a QR code for inviting someone in person and buttons for common messaging apps are all on the Invite friends screen. The link remembers who invited a friend even if they look around the site first and sign up later.
What we ask you not to do
Please do not post your link in groups you were not invited into, send it to strangers, or spread it across comment sections. It annoys people, it gets links blocked, and it does nothing for the reputation of a game you have chosen to recommend.
What gets accounts closed
Opening accounts for yourself under other names, creating accounts for people who have not asked for one, or inviting anyone under 18 all break the rules. Accounts opened only to collect rewards are closed and their rewards removed. One person, one account, always.
