Create more and more valuable materials: drop objects into the box and connect the same ones. There are many types of stones, metals, and jewelry in the collection, each with three stages of development and an educational card with facts about history, mining, and value. Unlock new materials, find crystal energy bonuses, and use special tools when the field gets tight. Calm music, pleasant physics and vivid effects make each successful combination especially enjoyable.
Move the next object with your finger or mouse and release it over the box. Two identical objects of the same level combine to create the next one. Make sure that the stack does not stay above the red line. A regular reset consumes energy, and rare upper levels are slightly more expensive. After a lot of resets, the scale gives you the best item that has already been opened. Sometimes a crystal piece of glass appears: smash it with a falling object and get energy. The point-delete button removes the selected item, and the super-lock explodes up to seven random items.
