Sign in

You never have to sign in to play — every game, every archive day and every leaderboard works without an account. What one adds:

• Sync your streak across devices — an anonymous player is identified by this browser's cookie alone; an account makes phone and laptop one record, so clearing the browser stops costing you a day.
• Claim your leaderboard name — appear as yourself on the daily boards, or stay off them entirely.
• Keep your lifetime history — every finished day in every game, yours to export or delete.
