Itchy Knee Sun She Go Rock! IQ Testing Here!

A friend of mine, Samantha (take a bow), sent me a link to a very taxing game. The rumour is it's an IQ test used by Japanese companies. The object is simple, get all people across the river. The test can now be taken here. The rules are as follows:
1. Only 2 people on the raft at a time.
2. The Father cannot stay with any of the Daughters without their Mother's presence.
3. The Mother cannot stay with any of the Sons without their Father's presence.
4. The Criminal (Striped shirt) cannot stay with any family member if the Policeman is not there.
5. Only the Father, the Mother and the Policeman know how to operate the raft.

To move the people click on them, too move the raft click on the pole on the opposite side of the river. Finally to start the puzzle, click on the big blue circle on the right of the site. I did it in just under 10 minutes.

If that really floated your boat and you want some more, you can do a free online IQ test here. FWIW I've done two (real) IQ tests in my life and got 138 and 155, making me eligible to join Mensa. Let's see if alcohol has really killed off my brain cells in recent years, I post my online score soon... (BTW the title is 1, 2, 3, 4, 5, 6 in Japanese)

UPDATED: My online lunchtime IQ score is 127. Not great but it'll do. My end of test report gives us this piece of salesman psychology: "You've got a very experiential way of learning and a strong mathematical mind. You're able to whittle even the most complex situation down to comprehensible component parts. In short, you have mastered the art and science of precision. That's what makes you a Precision Processor." Who has the time to best my score?


  1. Gutted, I got 126 for my Sunday morning test. As for the Japanise puzzle I think the answer is simply to shoot the prisoner, problem solved (surely you get extra points for thinking outside the box!!!).

  2. I think it's about time to post the solution:

    Send the Police Officer (PO) and the Criminal over first (it's the only move you can make). Send the PO back and then send a boy and PO back and then the PO and criminal back again. All you have done is move one boy to the other side.

    Next you need to send the other boy over with the father. Send the parent back so on the far side of the river you have two boys. You can now send both parents over and just the mother back. Half way there and this is where most people get stuck.

    Now is the time to send the PO and criminal over, then send just the father back. You can then send both parents over and just the mother back. These two full trips have solved the puzzle. You can now use the mother to ferry the one girl over and use the PO and criminal to go back and gerry the final girl over with the PO (leaving the criminal stranded alone just like in the beginning) and finally send the PO back again to get the thief.

    You will then have a animated screen that you sit back and admire, thinking "that is good looking"!
