On the home screen, tap Daily Challenge. Today's Challenge shows the mode, the difficulty, the deck and the XP it gives.
The same grid for everyone
Same grid for everyone on the first try. If you try again, you get another grid: a lost game cannot be replayed on a board you already know. The difficulty changes every day, the mode every three days and the deck every five days.
Share your result
Tap Share my result. Your result is a row of squares, one per move: green for a pair, red for a miss. It shows how you played without revealing the grid.
Extra XP and a streak
Winning the challenge gives extra XP: 100 in Easy, 200 in Medium, 350 in Hard. Win it several days in a row to build a streak. Then the card says Completed today!
