Crossing the river game
is considered one of the most popular IQ games as it requires lots of
concentration, strategy and critical thinking in order to beat the game. The objective
of this IQ game test is very simple: the player must transfer all the
characters from one side of the river to the other side using a raft. However, the
tricky part here is the game’s rules; making it more interesting and mind bugging.
The characters in this game are a policeman, a criminal, a mother, a father, 2
daughters and 2 sons. The restrictions/constraints of the game are listed below.
- The raft can only carry at most 2 passengers at a time.
- Only the police, the mother and the father can operate the raft.
- The father cannot be on the presence of the daughters without the mother
- The mother cannot be on the presence of the sons without the father.
- The criminal cannot be left alone with the family without the policeman
