Snijpunt is a game played on a 6x6 board:

POINTER ZONE - The bottom row and left column excluding the bottom-left cell (which is not used).
FIRST TURN - White drops a stone in the pointer zone row. Then Black drops a stone in the pointer zone column (these two pointer stones). Then Black drops a black stone at the intersection of the two pointer stones
TURN - On each turn, each player moves his pointer stone and drops a stone at the intersection.
Dropping a stone at an empty cell is mandatory, if possible.
Otherwise, the intersection stone changes color.
GOAL - A player wins by making an orthogonal 4 in-a-row.
An example

White's turn. He can move to the 'b' or 'c' column, dropping a white stone at the green or red dot. Dropping a stone at the red dot would be a bad move, since then, Black would reply moving to row 5. White would be forced to move to column 'e' and Black would win moving to row 4.

I think the actual goal (orthogonal 4 in-a-rows) is very restrictive. The first phase translates into just filling the board, and then try to outperform the adversary in the swapping moves. If we allow diagonal 4 in-a-rows the game gains dynamics and becomes much more tactical, which is suitable for such a small playing board.

There's a website with information about the game (in Dutch). I wish to thank Hans Bodlaender for translating the rules.
