Cube Spark vs Fireworks Sudoku

Cube Spark is a simple but challenging game that is all about destroying cubes by tapping the ones that match the color of an electrified cube. The target color changes over time and your score grows faster and faster as long as you continue to make matches quick enough. There is a laid back "Zen Mode" that doesn't have any penalties for clicking the wrong color and a more competitive "Challenge Mode" that takes a life away for every wrong selection. You can destroy single cubes with a tap or you can destroy groups of cubes quickly by swiping your finger across them. There are score leaderboards to climb and plenty of Achievements to discover and unlock. So, stop reading this and go spark some cubes!!
