Cotocau.
The traditional card game of Alcoi, now digital
About the project
Cotocau is the digital version of coto and cau, the most emblematic card game of Alcoi and its surroundings. Played every year in the social halls of the filaes, especially on Fridays and at the world championship held in October, it's a game deeply woven into Alcoian culture.
This project was born from personal initiative, just a genuine desire to build something useful and free for the community we grew up in. Together with Ivan L. (design and UI), we wanted to make this tradition accessible to anyone, from anywhere, at no cost.
The platform faithfully adapts the two most popular game variants played in the filaes, letting players join open matches or create private rooms to play with friends regardless of distance.
