Move the counters one at a time to an adjacent empty space so as to put them in numerical order around the outside and leaving the center circle vacant. The ordering may either be in the clockwise or counterclockwise direction.

The minimal solution is 17 moves.

"Reverse Solver" variant:

Even if you do not find the minimal 17 move solution, you may want to know the minimal number of moves required to find one of your own solutions. To do that, launch another instance of the game and select the reverse solver variant. Using the board editing feature, manually copy the piece layout of your solved puzzle to the reverse solver's board. Set the difficulty and thinking time sliders to their maximum setting and select the computer as the solver. When you start the computer thinking, Axiom will then find the minimal solution by solving the puzzle in reverse (i.e. from your solved position back to the start position).
