Are there any good minigame-like PC games that are great to play in short busts or to pass the time if you're downloading/installing something? Sometimes I'm in such situations, however I don't want to boot up something that I can get stuck into, or something that requires a lot of attention for a while.
I'm talking about the sorts of things you'd find in Warioware, or Rhythm Heaven. That sort of thing.
Hanafuda - the Flower Cards. Game despite being abstract at the beginning, after a few rounds becomes very simple. However, I don't use Kyushu Style ruleset, as I stick to the Tokyo Style (literally two combinations replacing two other). Not the kind of game that you described, but also very neat one.
There are also Hanafuda games on Android. Just put "Hachi Hachi" or "Koi Koi" into the search. The first is way different than I have shown here.
