Here's a project I've been working on which will cure your terminal boredom. This version of Tic-Tac-Toe is One-Sprite One-Script (like my other latest projects and has 3 AI skill levels and 2 player support. Also, this Tic-Tac-Toe game can be moved to anywhere on the screen and is fully rescalable. The Easy AI skill level is completely random and will not take your moves into account. The Normal AI skill level will block your moves, but the rest is random. The Hard AI skill will block your moves and attempt to win, and succeeds much more often than the others. Calculation in Easy is almost instant, whereas hard takes a few seconds. Who is X or O is random, and O always starts first. To set difficulty to Easy, press e. To set it to normal, press n. To set it to hard, press H. Finally, Have fun! (and Love-it if you enjoyed yourself writing little symbols on a grid)
