RULES:

Clixit is an offline multiplayer game (4-6 players). It works by inputting the same numeric seed in every device running the game. After that, each player has to input the number of people who will participate, and each one must choose a different deck. Doing so, the game will randomize a different deck for each player, and the match starts.

It follows basically the same rules as the card game Dixit, so if you played that game before, it will be very straightforward.

Note: In each turn, every player has to input the other's choices too, so the game can go to the voting screen.
