Grid RelayDAY STREAK

A badge unlocks when you hit its day mark, and it can still upgrade while that part of the streak is still open: Easy, Medium, Hard, or Extreme. If the streak breaks, a later run can still come back and improve that same badge.

Gold shields

Gold starts with one shield, banks another every 7th consecutive daily clear up to two total, and auto-burns 1 for each missed day until the bank is empty.

Sign-in keeps your streak progress attached to you, with badges, prestige tier, and shield state saved across sessions.
