I don’t understand the scoring method for challenges. I solve a challenge worth 400 points and get 2 points. Why?
This is a common point of confusion. If you track your score at the upper right of the screen, you ALWAYS get awarded the full point value of each puzzle. There is no partial credit for puzzles!
The “+ XXX” animation you see when you complete a puzzle shows how far you’ve advanced in the rankings upon completion, which will vary depending on how other people are scoring
