The task in the Domino Roll game is to restore the picture, which is made up of multi-colored dominoes. Initially, at each level the bones are standing, not lying, and you need to arrange them to get the finished mosaic. To solve the puzzle you need to find the correct element, which will trigger a chain reaction. You only have one attempt to complete the task. If the tile you choose is a guide tile, only part of the picture will be restored, but you need all the dominoes to fit and not one of them left standing in the Domino Roll.
