Connect Four (1.7.4)

Connect Four is a two-player game first sold in 1974, where the goal is to get your pieces into a line of four in the 7X6X6 grid. In this version, the pieces are red sand and sand.
This is my first minigame map that I have actually finished, and I plan to update it soon, so that it will automatically detect when someone wins. Currently, you must manually decide the winner and reset the board.
If you make a Let's Play for this, feel free to send me the link 🙂
