Are you waiting for something? Like... your turn, the cooking time or anything else? Why don't you put some blocks together?
Well, Metris does exactly that. You need to climb over steps of increasing height, using just the pieces of Tetr... I mean, using completely-original shapes that have not been copied from any other game!
Sarcasm apart, it's a quite relaxing game for passing some enjoyable time. You'll have to use logic and creativity to overcome unlucky combinations of shapes, but it's nothing hard, provided you're good at holding your nerve!
