Games
Kuhard
A ridiculously complex game. In appearance, it looks like chess since it is played on a checkered board using a variety of pieces with their unique abilities. However, the rules are completely different. Learning Kuhard is an exercise of pain and it takes several years just to become a decent player. This is due to how convoluted it is. Winning conditions, and even in some cases, pieces' movement, change as the game progresses. These changes can be triggered by a variety of conditions such as a certain number of turns played, how many pieces have been removed from the board, and even the date and time. At the start, the goal is to kill the opponent's commander, but it can later become crossing the board, eliminating all of your opponent' pieces, or killing the cooks, and more. Due to its complexity, Kuhard enjoys very little popularity, though those who love it are passionate about it.
Kuhdrid
A streamlined version of Kuhard meant for the general population. Kuhdrid is similar to Kuhard at the start of a match. It uses the same pieces and board and the initial rules and winning conditions of killing the opponent's commander are the same. The major difference is that Kuhdrid rules are fixed and do not change as the game progresses. Also, a few of the more complex pieces have simplified abilities. Due to its straightforwardness, Kuhdrid is far more loved than Kuhard by the masses. True Kuhard experts, however, tend to dismiss it as child's play and lament the fact that the complexities of Kuhard aren't appreciated as they deserve.
Rubarg
Rubarg is similar to pools, but played on a hexagonal table instead of the familiar rectangle. The balls are arranged in a lozenge at the beginning instead of a triangle and there are 24 of them. Player one must sink balls one to twelve, while player two tries to do the same with balls thirteen to fourteen.
Card Games
There are card decks in Nirnivia and Ostark, but they are presented differently to those on earth. Each deck has forty-eight cards in it. Each card is identified by a shape and color. There are sixteen shapes, them being: A square, a rectangle, a circle, an oval, a triangle, a parallelogram, a lozenge, a trapezium, a pentagon, an octagon, a star, a cube, a cylinder, a sphere, a pyramid, and a cone. Those shapes are available in three colors: Red, green, and blue. Many games can be played using these cards, most in groups as adversaries, and some alone.
Yombalk
A game where colored stones are posed on a board. Each player places a stone of his/her color every turn. To win, one must align four stones of the same color. It gets more complicated since only ten stones of each color can be placed on the board, after that, they must be switched with other stones.
Video games
There are video games in Nirnivia but they are rather primitive. Home consoles aren't available yet, and so they come in the form of arcade machines and are fairly rare. Most of them are single screen affairs with simplistic gameplay using a joystick and one or two buttons.
