In Color Pillar: Stack Game, you have to collect colored platforms to build a higher stack and achieve the goal of the game. Every level will present you with a new challenge. You need to be aware of which colors you need to collect and build the correct stack to achieve the goal. Every time you fail to build the correct stack, you will lose points. 

You need to be careful and try to collect as many diamonds as possible to avoid losing points. When you reach the goal for each level, you'll get a reward. You can use the diamonds to increase your speed and get more points. Every level has a leaderboard where you can see how you did compared to other players.
