The operation is as follows:

Select the number of steps with the pushbuttons at the top of the page.

Available waiting time (seconds) is shown in the box below and counted down from now.

Move the marker in the game plan.

Click at the number for the current problem.

The problem is displayed. 

If the answer is ok - fill in the number of the solution in the protocol before the end of the time.

Press next player.

The protocol can of course be saved on a computer that anyone can access

  Example of The protocol over the players position looks like this:

                   Start position       First position     Last position

Player 1        0                         3                     5                      2 steps is ok.

Player 2        0                         0                     5                      missing one step           

Player 3        0                         4                     4                      one step missing

-------------------------------------------------------------------- 
You must not fill in all positions. It is only the last one that is interesting.

Tip for 2 players or more:
One move at a time for each player.
Use the many steps with short thinking in the beginning as the problems are easier there.
In the end the problems are much harder. Use long time and fewer steps there.
