The game is played on a empty limited 8x8 board. Also, each player has 20 soldiers and 1 King.
Black should jump to d7 (the blue cell) to win at b6 in a diagonal 4 in a row.
I caught this game rules on the oldie Jeux et Strategie, a game and puzzles magazine that crossed the 80s and my youth. I only have some old xeroxes so my information about this other games are very limited. If someone has more information's about abstract games present on JeS please send them to me.
