Monoka

Monoka is a multiplayer card game about strategy and confusion, where the goal of the game is to be the first with no cards, although doing so can be an arduous task, as it is up to you to figure out the game rules and how each card interacts with the last!

As an example, look at these two cards here:

Despite them having the same color, you cannot place them on each other.

Additionally, there are cards that only work in 1 direction, like the cards below, such that you can place the left card on the right, but not the other way around

There are many other situations like this, but I implore you to discover those yourself.
