How can I improve my high score (it's currently 37)?
Mostly, people seem interested in their best score at Puzzle Rush, which is interesting but often a rare statistical outlier. An alternative viewpoint is to try to be consistent in your scores, by avoiding low scores. I thought I was quite consistent with an average just over 75% of my best, but how about this? https://www.chess.com/member/gothgirlgames Average puzzle rush score 85.5% of best (pretty good best too) - 31.78 / 36 . The equal top of the all time rankings has managed it while being pretty consistent too, with an average of 39.81 for a best of 55.
