We invite you to our relaxation puzzle Bubble sort, where you will operate with colorful balls. At each level, the balls will be distributed in transparent glass flasks. Your task is to have only balls of the same color in each flask. If this is not the case, you need to sort. Click on the selected flask and the top ball will jump out and hover over it. Next, click on the container into which you want to throw this ball and proceed in this way until you have sorted all the balls. If there is only one empty bulb left, this is not considered an error.
