A game of Yontel in progress

Yontel is a pointless game designed by Louigi Verona, the goal of which is to create a rectangle out of an unlimited amount of xubusei.

A mistake: red area marks a gap that is impossible to fill with a xubus

Due to the shape of the xubus, the goal of the game is impossible to achieve. However, it is possible to lose by creating a gap that cannot be filled. Therefore, the process of the game involves growing the xubus field, at the same time making sure there are no gaps.

Yontel can be played on paper or with physical pieces, arranged into a jigsaw puzzle structure.
