About Stack Color GameStack Color is a colored block stacking game. Pieces come in above the stack and move from side to side back and forth. When a piece is correctly aligned over the stack hit the mouse left click button to lay the piece. Each perfectly timed piece is worth 5 points. When you get 3 placements perfect in a row it activates a stack bonus which further boosts your score. If you get a piece on the stack but do not have perfect timing you will score a point and your next colored block will be slightly shorter. Keep playing until you miss the stack and see how many points you can score. This is a JavaScript web application which uses cross-platform mobile-friendly HTML.
