2. Play: Click on the marble you want to move. Then click on the empty hole to which you want to move the marble.

3. Play again. Click on the same marble as when choosing colour. (This also STOPS an ongoing game)

If you find it too easy to win, you could change the level by checking another number in the margin.

Level  1 and  2  give a warm up if you're new or it was long ago since you played - then the resistance increases.

The computer will test one move ahead for each level, and from Level  5 this will be noticeable in the response times. How far the computer has proceeded could be seen in the status line, where "36:14" means that the computer has 36 first moves to choose among, and is examining the 14th.

Highest level depends on your patience and computer. (Level 7 is probably most for angels with super computers)
