You get exposed to a variety of puzzles with a variety of ratings. Your score on any one puzzle is based on the difference between your own puzzles rating and the puzzle rating itself and how much time you took to solve it.
This is from your puzzle stats:
You can see the different ratings for the puzzles, how many moves they had, how many of those moves you got correct, the target time for the puzzle (which is based on your rating), the average time people take, the amount of time you took, the score percentage and the score you received.
You should take as much time as you need until you are sure you have solved the puzzle. You always get at least 5 points for the correct answer.
Is the difficulty of the puzzle based on your rating or the tier? Because it seems as if the puzzles have been getting harder as I’m going down in rating and I don’t know if it’s due to the tier. It seems as if my rating will never recover
