The River IQ game

Many of you may have seen this before, but it was long on my to-post list, so I figure I’d finally post it today.

I came across this test courtesy of my Father some nine months ago, and I must say it took me a while to arrive at a solution.

This is supposedly a test given to Japanese job applicants to gauge their IQ levels. The task is to transport a party of eight people across the river, following these rules:

  • No more than two people can be on the raft at any point,
  • Only Mom, Dad and the Policeman know how to operate the raft,
  • Mom cannot be left with any of the boys when Dad is on the other bank,
  • Dad cannot be left with any of the girls when Mom is on the other bank,
  • The prisoner cannot be left with any family member when the Policeman is on the other bank.

Dysfunctional family aside, – what is it with Japanese? – the first time you try solving this puzzle, I bet you will find yourself perplexed at some point.

Click the big round button to start – and good luck!

    Couple of confusing moments, but got through anyway in about 5 minutes. Is there a spеcific purpose for parents hitting the kids? 🙂

    Probably, that illustrates the strictness of Japanese parenting?…

    But you are an IQ giant, Kostyan. My first try, I spent about 20 minutes figuring this out…

    Well, whatever urban legend surrounds this thing is completely wrong, because the language is Chinese. Simplified Chinese, in fact, which places it in the PRC, and not Hong Kong or Taiwan.
