One friend of mine showed me this mind-breaking game. It’s free and it’s dangerous.

The rules are simple:

• You are required to help these people cross the river.
• The policeman can’t leave the criminal with other people.
• You can’t leave father alone with the girls as well as mother with the boys.
• Children can’t cross the river without the help of grown-ups.

Now that you know the rules, go try it. Oh yes, and for those who don’t know Japanese:

Press that big blue button to start. ;)

Good Luck!
