Interesting confusion for several players

I bought the game last year at the game fair. My son was at this time 3. Playing the Geistertreppe gives me with my son and my niece a lot of fun together. But three players, there must already be so confusion arises and mind. 2 players should younger children (7-8 years would appreciate to) be. As you yourself often to watch the children stops better and to keep the figures in mind we no longer know eventually what was his own figure. So, in my opinion, an amusing little game for 3-4 players. The only drawback: The board is not so easy to understand for young children.
