Every game works without one. An account gives you a leaderboard name nobody else can use, marked with a ✓ on the boards, and carries your personal bests to any device you sign in on. It needs an email and a password - nothing else.
Everything else on the site works: play as a guest, pick a name below, and your scores go on the boards under it. Check back for accounts.
The best you have posted in each game, from every device you have signed in on.
Nothing yet - play something.
This removes the account from Cognito and every score it holds from the leaderboards. It cannot be undone. Type your name to confirm.
Your scores go on the boards under a name you pick, tied to this browser. Clearing site data makes you a new guest - an account is how you avoid that.
What is kept and where is spelled out in the data policy. The two buttons below are the short version.
"Remove my scores" deletes every leaderboard row this player holds (guest rows from this browser, or the account's rows when signed in). "Clear this browser" wipes the personal bests, name, ids and session stored here, and signs you out; game saves such as the Michidex or the Meowney Printer bank are kept unless you clear site data in the browser itself.
