This is an addictive game that will keep the users playing since everyone is curious to reveal the next level. The game has unlimited levels and it’s a very unique concept. With a little code change, you can convert it into RGB (red, green, blue) color format, or even use both formats as the user makes progress or let them choose RGB vs HEX.
