A game of Yontel in progress

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

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 create a situation when a gap in the pattern is created. Therefore, the process of the game involves growing the xubus field, at the same time making sure there are no gaps.
