Wondering why your points are decreasing even though you're solving more challenges?
In lots of levels in order to see a hint, you are agreeing to 'spending' a certain amount of points to reveal the hint. The cost of a hint is very much dependent on the challenge, in particular, how difficult it is. You should expect a higher cost to reveal hints for harder challenges!
If you don't want to use up points on revealing hints but are stuck on a challenge, check out this article for other ways to help solve challenges!
