The Daily challenge card on the home screen opens the sequence of the day. Every player gets the same sequence on the same date. It changes at midnight, on your phone's clock.
One try, one goal
The challenge always uses 6 colors at normal speed, and starts with 3 colors. Each day brings a variant, in turn: Standard, Mirror (backwards) or Shuffle (the buttons move). The goal follows the variant: 8 colors in Standard, 6 in Mirror, 7 in Shuffle. You have one try a day, and no second chance.
A streak of goals
Each day you reach the goal adds one to your challenge streak. The card shows Goal reached! or your result, then New challenge tomorrow.
Share without spoiling
The Share button of the card sends the challenge number, your result if you reached the goal, your streak and a row of squares for your recent days: green for a goal reached, red for a goal missed, white for a day not played. The sequence itself is never in it.
