Space is a light, brief, blockade game where the last player who can move a jumper wins.

There are ten blue pawns, ten yellow pawns and one green neutral pawn. There are two blue jumpers and two yellow jumpers. The board is a 5 x 5 grid. Put all the pieces on the board in random positions. Blue removes one blue pawn and yellow removes one yellow pawn. These are the two spaces, unoccupied positions.

Players can only move pieces of their colour, while both players can move neutral. Pawns are moved to an orthogonally adjacent position, as long as it is unoccupied. Jumpers are moved as far as they want across a row or column as long as they land on an unoccupied position. A turn involves moving a pawn and a runner, in either order, and moving the pawn is optional. If you can't move your jumper, you lose.
 

How good is this game?
Well I think it's the bees knees, whatever that means. It's a simple, easy, pass time. Not as dweeby as it looks.

Construction notes:
You can make it with whatever pieces, like glass pawns, chess pieces and a 9 x 9 inches (23 x 23 cm.) paper board. But the setup is awkward. It is best made with uniform discs, which also has the side benefit of being portable and easy to store. No board. These are plastic discs from Scholar's Choice with holes for the jumpers made with a drill press.

Ludological notes:
I'm going to introduce two new terms. But I forgot what they are. Blockade something.
 
 
 
 
 
 
 
 

This could probably use bigger holes, quite doable, and the plastic warps a bit around the drilling, which you don't really notice. It functions. I store these feather-light discs in a little wedding gift bag, from Michaels. This is rugged, tiny, portable, easy to learn, easy to play, and - the point of discs - easy to set up.
