Swish & Squeeze
Swish & SqueezeSwish & Squeeze are 'bead capture' games, but no mancalas. The basic idea behind both is simple and original, yet I'm not quite sure how I got it, but both find their origin in the hexplane and Squeeze came first. I made square translations, but discarded them later because though not less challenging, they were less elegant.
The diagram shows an initial position for either game. It is made up completely by one player, who may be, or better be, familiar with all its intricacies. He places the six rooks around the edge and 19 beads in the 37-cells center. The other player may choose a color at the cost of the first move, or vice versa.

First to capture ten beads wins.
