River IQ Game

Played this flash game today (actually tried for a while yesterday and gave up!).

River IQ Game

The setting is:
A family of six (father, mother, 2 daughters, 2 sons) got lost while hiking. Unfortunately, they also met an escaped convict who almost harmed them! Luckily, an off-duty policeman was hiking nearby and caught the convict. Now, they are all lost in the wilderness with no contact with the outside world. They finally reached a river with a 2-man raft and they need to cross it to reach for help...

Rules of the game:

• Only 2 persons on the raft at a time
  
• The father can not stay with any of the daughters without their mother’s presence
  
• The mother can not stay with any of the sons without their father’s presence
  
• The thief (striped shirt) can not stay with any family member if the Policeman is not there
  
• Only the Father, the Mother and the Policeman know how to operate the raft

Okay... i am pretty dumb and could not solve it. And I even got lazy and googled for a solution. (bravo the power of google!) Try it! (Do not get lazy like me and click on the solution in my comments =P!)
