About Sphere Mastery GameSphere Mastery is a Sokoban-inspired pushing game where you move a white sphere around the playing field. Whenever a yellow sphere is adjacent to your placement the white sphere pushes the yellow sphere over a square away from it. You can jump to any position on the grid with each move, but have a limited number of moves to fill all of the cell locations that have a yellow outline with either the yellow spheres or the white one. Unlike in regular Sokoban games you can push rows of 2 or more spheres, though the nearest one must be in an adjacent cell. Similarly, when you jump into a location you push in all 4 directions instead of only 1 in regular Sokoban. This is a JavaScript web application which uses cross-platform mobile-friendly HTML.
