Ring on Tube (Ring on Tube)
Surely you remember what a corncob looks like, or maybe today you enjoyed boiled and seasoned with butter corn. Our object in the Ring on Tube game looks almost the same. This is a pipe with elements glued to it, similar to corn kernels. The task is to clean the pipe from foreign bodies. To do this, you will use a specially designed ring made from a unique material. This is know-how, which is kept under the strictest confidence. When you press the ring, it can shrink or expand, changing the diameter at your discretion and you, depending on the size of the pipe to be cleaned. You must reach the finish line and not trip on ledges or empty gaps. Throughout the cleaning, you should only manipulate the ring.
