Swipe up, down, left and right to move all the color circles. But be aware, this is not a 2048 clone. You are NOT matching numbers or colors here. Gameplay is based on the additive RGB Color Model. In RGB+ you add primary colors together - Reds, Greens and Blues - to make secondary colors. Cyans, Magentas and Yellows are secondary colors that when combined equal White. After every swipe a Red, Green, or Blue circle randomly appears on the grid. To help you score big and clear the grid, combine White circles with one another. Rack up a high score until there are no moves left. FEATURES: Minimalist design Fresh theme and gameplay Familiar sliding block puzzle mechanics Leaderboard Share highscores Special Thanks to Thomas Young, Hermann Helmholtz and James Clerk Maxwell. RGB+ is fresh take on the sliding block puzzle genre made popular by Threes and 2048.
