Alignment

The principle is very simple.
On a gridlined sheet, you need to check the empty squares.
A cross mark shows the square that you selected.
The goal is to align your signs next to each other, horizontaly, verticaly or in diagonal.

As soon as 3 to 5 side by side symbols form a line, you are awarded one point. The opponent is obviously looking to do the same.

As a wise strategist, you too will aim to block your opponent from marking points by positioning your symbols in such a way.

The first to reach the required number of points is the winner.

Once you selected a square, its the opponents turn to check an empty one which will marked with a circle.

And like this, once at a turn the squares are being filled.
