KREPZEN is a game designed by Néstor Romeral Andrés, from Nestorgames, and implemented by Garage Imagina. Place the 3×3 group of balls on the board, trying to match as many colours of existing balls as possible. For each matching colour you’ll get 5 points. For every ball placed on an empty space you’ll get 1 point. If you place a ball atop another ball of a different colour a black ball will be created, that you could remove by spending points.
If you’ve done well enough, you can submit your score to the hall of fame!
