Although I also have Push It, which simply can’t be beaten for compactness and portability, Planepita is a lovely little production which adds some fun twists to the same disc-flicking genre without taking up much space in the shelves.
The planet board and the discs are all magnetic such that when you flip a disc face-down it sticks to the surface making it much harder to dislodge, but also making it worth only half as much for area-majority. You can choose to flip a disc after flicking only if it stopped in a different zone to the black disc. At the end of the round, once all discs have been played, whoever has the majority in each of the three zones scores points. But not before the black disc (which starts in the centre but may very well have moved) hoovers up every face-up disc in the same zone as itself (it’s a black hole!), removing them from the board.
The top of a face-up disc attaches to the bottom of another, so (delightfully) the black disc will pick up any face-up disc you touch it to the top of, and then you use that disc to pick up the next, until the black hole is trailing a little column of discs which you lift off the board and deposit on the little separate black hole mat :).
There are also a handful of little circular tokens which might be assigned to a disc and, once again, you just pop them on top of the disc and they’ll stick there. Neat!
