Beat a grandmaster puzzle!
Watching the balls split at the end is a very satisfying win to the puzzle.
I found the random + row/column requirement + number of tiles felt too difficult to strategize. I tended to play until I was half out of tiles and then start thinking hard. But pushing to the harder difficulty levels, I really got into the strategy.
Weirdly, in my memory some of the puzzles are more than 3x3, but it looks like all difficulties are the same. I guess it just seemed more daunting…
Great work!
