One board for everyone
Daily challenge, on the home screen, opens today's board. It is one of the levels 8 to 29, with the order of the trains reshuffled for the day: a board you know, played differently.
Every player gets the same board on the same date. It changes at midnight, on your phone's clock. The daily challenge opens once you have cleared level 8.
Your streak
Each day you win adds one to your streak, shown with a flame on the home screen. A day missed starts it over.
