River Crossing Puzzle: Hard!

Ian let me know about this challenging river crossing puzzle game. The graphics are well done, and the little animations are kind of amusing:

(To play, click on the image and then press the big blue button. Note the rules below!)

Here are the rules:

1. The raft can carry only 2 people.

2. The father can not be left with any of the daughters unless the mother is present

3. The mother can not be left with any of the sons unless the father is present.

4. The criminal can not stay with any family member unless the guard is present.

5. Only the father, mother, and guard know how to use the raft.

Click on the characters to move them on/off raft. Click the red control ball to send the raft across the river.

Couple of answer submissions are already in the ‘comment’ section; try to solve it first before giving in and looking! :)

    Also… why oh WHY does the mother hate her sons, and the father hate his daughters? Unless maybe it’s the secret lives of a Brady Bunch-esque family… dun-dun-DUN!!

    this game is a test that japanese used to hired people, , I have done it before and found symetrical answers (first boys then girls), (first girls then boys), Is a really cool logic game, harder that the river puzzle that implies a wolf, a chicken and corn.

    I found in the web a cool test that implies attention, memory and proccesing speed, just get in google a put luminosity, then calculate your lumus IQ, i don“t care about the score, but the test is nicely done.
