Kolumno is a puzzle game where you drop a ball down the side of a sphere aiming to reach the bottom without being blocked. Your task is to manipulate the ball so it fits the rotating elements with gaps in them.

This might seem like an easy task, but things quickly become more difficult with added mechanics like stopping the ball mid-fall to pause at key spots, shrinking or enlarging the ball or even drilling into the blocking elements.

While the graphics easily identify the game's origin on smartphones, they are both simple and stylish. The game is easily underestimated. The initial levels are still easy, with only one action to press and unlimited time, but soon actions need to be combined in order to successfully clear each level.

Next to figuring out the right order of actions, actually timing them correctly requires increasingly strong reflexes. The different levels are accompanied by a relaxing soundtrack.
