Hi. Thanks for this. Things I like: they're from actual games; you're given previous player; you're given highest move (though occasionally strange that the AI doesn't find anything higher....). Things I'd like to see different: to see what the AI's play actually was, after you've played; for the scoring system to take more notice of how well you do versus potential points and less of how well the previous player happened to do; (and this is the biggy for me) to have a rating system that puts more weight on how well you do with the games you play than with how much you play. Right now it's an awful lot to do with volume of puzzles you complete, which could be one metric but it's not the one I'm interested in.... Thanks!
