Circles Up: build a tunnel — is a puzzle game where you need to stack rings on top of each other. Tap just in time so that the circles stand up straight and line up in a high tower. If you make a mistake, the circle will become thinner, so in the future you will have to aim even more precisely! How high your tower will be?
