4 en raya is an Android game developed by Jesús Merino that offers a modern twist to the classic game of Connect Four. The game's retro 8-bit aesthetics give it a unique and nostalgic feel.

The objective of the game is to create a line of four of your pieces before your opponent. You can play against the computer or another player on the same device. Additionally, the game offers a mode where it doesn't stop when someone makes four in a row. Instead, the game continues until the board is filled. In this mode, the winner is the one who gets the most four in a row.
