### River Crossing Puzzle

For teachers and students looking for a more challenging brain teaser, here is  Smart-Kit's highly popular River Crossing Puzzle Game! The instructions and rules are in the game, but in case you want to read them here:

A farmer, his son and daughter, and their pets need to cross a river. The pets are an aggressive dog, 2 hamsters, 2 rabbits. There is a small two-seater boat they can use. All 3 people know how to use the boat, but none of the animals can. Click the motor to use the boat.

1. If the farmer is not around, the aggressive dog will bite everyone and everything.

2. If the daughter is not around, the son will tease the rabbits.

3. If the son is not around, the daughter will tease the hamsters.

4. The hamsters and rabbits get along fine with each other.

Click on the characters to move them on/off the boat.

Couple of answer submissions are already in the 'comment' section (although these are for an older river crossing puzzle we had up; try to solve it first before giving in and looking!:)

Another Smart-Kit exclusive students will love to compete on is the carnival based puzzle game: Cover the Spot! Or you may try another great brain teaser: the Frog Jumping Puzzle!

Don't forget to check out Smart-Kit's full archive of amazing yet safe school games that make for great Edu-tainment!

Here is an earlier River Crossing Puzzle you can try to figure out (more of static logic brain teaser).

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.
