Puralax is a simple puzzle game where you need to paint every colored tile into one single color to complete each level. Each level has a different target color, indicated by the color of the top bar on the screen. Rules are simple: You can move colored tiles between white empty cells in vertical or horizontal directions (one cell at a time), or you can paint a neighbor tile by dragging one tile into another. Each tile has a limited amount of moves, shown by little white dots inside it. When you paint one tile, you can generate a chain reaction that will begin to paint every attached tile from the same color. The first six levels comes with an assistant that remind you the rules and tells you which tiles move where. So, what are you waiting for? Start painting, and remember... colors are alive!
