Same board as in Three Men's Morris
https://en.wikipedia.org/wiki/Three_Men%27s_MorrisTwo players.
Players have four pieces each. Different color between players.
You start with the board empty. Players take turns placing pieces one-by-one on the board.
Once all pieces have been placed, therefore leaving only one spot open, players take turns moving a piece around.
Pieces move to one adjacent spot. You cannot move to a spot that is occupied by another piece. To move to a spot, it has to be connected to the one you are at.
You can capture an opponent's piece by jumping over it, landing at the spot behind it. The captured piece is removed from the board.
The one who has no pieces left loses.
Any idea what it is called?
