"C4" is a very easy-to-understand rule game that you win by arranging four circles.


The player can just click on the column where you want to place a circle.


When clicked, a red circle is placed at the bottom of the column. The player wins if you arrange four red circles vertically, horizontally, and diagonally 45 degrees in any direction.


When the player places a red circle, AI will immediately place a blue circle.


If you click on the column where the red circle or the blue circle is placed, the new circle will be placed on top of the circle on which it is already stacked. This "characteristic of c4" is that "the circles accumulate".


After that, if you put four red circles before AI it will win ... ...


Because I was not used to the stacking method at the beginning, I lost easily.


It is like this when I actually play. As AI puts a circle immediately, it may be settled in about 15 seconds as soon as possible.

AI is quite a tough opponent, but of course it is also possible to win.


Even human beings can easily play with paper and pencils, so it may be fun to play with friends and colleagues for a while to kill.
