The Telenet Puzzles
The following puzzles have the same starting position for the pieces and also the goal is the very same for each of them: just restore the logo (as shown in the picture above). Only the position where the restored logo should end up is different.
Puzzle 1: Restore the logo in the top left corner ... 121 moves.
Puzzle 2: Restore the logo in the top right corner ... 217 moves.
Puzzle 3: Restore the logo in the bottom left corner ... 157 moves.
Puzzle 4: Restore the logo in the bottom right corner ... 208 moves.
Since the logo can be restored in every corner of the board it is possible to go from one “solved” state to every other. The table below shows the minimum number of moves required to go between every two solved states (the starting positions are always with an L-shaped empty space):
