Each day you get five facts from topics like Movies, Sport, Science, Music, and Geography — plus one clue. Drag them into what you think is the correct order, then lock in your answer.
Lime green and orange feedback after each guess narrows it down. Five attempts, one puzzle, no interruptions. More points for faster wins on the leaderboard.
The preview cycles through a guess — same calm board you get in the app and on the web. No coins, timers, or pop-ups between rounds.

Higher is better. Win in 1 attempt = 6 points, down to 2 for a win on your last guess. Play but don't win = 1 point. Miss a day = 0 points and your streak breaks.
After you lock in a guess, lime green means that tile is in the correct position. Orange means the fact belongs somewhere else — drag it and try again.
