You read that right smarty-pants who like straightforward video games: according to its creator, Disc is the game for you.
This iPhone and iPad game from Tapush asks you to connect two discs of the same shade to create one much darker disc. Eventually you'll make grey discs, which score you points when you put them next to one another.
Here's the trailer, clever clogs.
Disc is out now and costs $0.99 / £0.69, with no IAPs. Below is the link to grab it from the Apple App Store.
