The crosswords were okay, although difficulty did not increase to an enjoyable level for as long as I tried it. The number of ads are just about tolerable though boring. But I want a relaxing game and when I had played for about twenty minutes some sort of competition kicked off and there was no way of opting out. After a few rounds of getting a leaderboard - as well as annoying ads - after every puzzle, I gave up and uninstalled because I was getting aggressively bored.
