Rainbow Stacker Game

Rainbow Stacker is an arcade timing game that challenges you to build the tallest possible tower by dropping moving blocks on top of one another. The game starts simply enough, with wide blocks moving at a leisurely pace, giving you plenty of time to line up your drop. But as your tower grows, the speed of the moving blocks increases, turning a relaxing puzzle into a fast-paced test of reflexes.

The core twist is that any part of a block that hangs over the edge of the tower is instantly chopped off. This leaves you with a smaller platform for the next block, meaning every slight mistake compounds into a much harder challenge. Surviving requires getting into a rhythm and anticipating the block's movement rather than just reacting to it.

Controls

• Click or Tap: Drop the moving block onto the stack.

Tips

• Get into a rhythm: The block moves at a consistent speed back and forth. Tapping to a steady beat is often more reliable than trying to track it visually.
• Don't panic after a chop: If you lose a chunk of your block, your next piece will be smaller but the movement speed remains the same. Re-focus on the new, smaller target instead of rushing to catch up.
