These puzzles are a 2 dimensional variant of the Egyptian Glory puzzles.
You can move a block and place it somewhere else but, after each move, every block must be fully supported by blocks below or the bottom.
Your goal is to reach a particular position with a particular block or more blocks.
Press the goal button to see your goal.
These puzzles are made using Macromedia Flash, I assume you will be automatically directed if you don't have the plugin.
