TAKTIK

Copyright (c)  1978?  Berliner Spiele

Taktik is played on a hexagonal board with the following setup (the black cells are not used):

 

MOVE - Each stone may slide any number of empty cells on any direction (they cannot jump other stones). GOAL - Wins the player that aligns his 4 stones.

 

An example If the black stone below moves to cell [1], it may slide next turn into one of the cells [2] to win the game. White can only stop one of those threats.
