A Game From My Childhood
GKAI is a logical game I played very well with pen and paper during my childhood among friends, family, and adults alike. Everybody loved the game because it's challenging and it involves critical use of logic.
I recently came across the game in an old diary which I used to play the game back then and I thought about making it available online for everyone to play.
Now, you can experience the same excitement and challenge that entertained us for hours. No pen and paper needed—just your brain and determination to crack the code!
