Idle counter game, wasn't bad. Ads were optional, and at 30 seconds to speed things along, it wasn't overly obtrusive..... Sometimes rewards wouldn't register, but that wasn't bad either... then I went to play an ad for a minor reward and was presented with a two and a half minute long commercial.... no way to back out, had to close the game... then every reward had a similar length... which I'm sure compensates the developers fairly well, but that is just way to long for an ad in a game.
