River Crossing Puzzle


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.

    I just saw this puzzle on the main page.


    Nice and not too difficult.


    While solving it, I wondered how the criminal can be kept alone on one bank without fleeing


  23. miwow98 | Profile

    this game is hard.


  24. Peramanathan | Profile

    M DD F SS TP | | —- Affecting factor here is Police and Thief , we should keep them both with family member or thief has to be alone. M-Mother, F-Father , D-daughter, S-son,
    T-Thief,P-Police

    1. At first we can’t move father – son or mother – daughter => thief – police man moved first, police come back


    M DD F SS | | P T
    M DD F SS P | | T

    2. Police and one boy(or girl) will go again, police will drop boy and come back with thief.


    M DD F S | | S PT
    M DD F S T P | | S

    3. Father and remaining son(or Mother and remaining girl) will go father will come back
    M DD TP | | FS S
    DD TP FM| | SS
    4. Father and Mother is the only possible move, Mother(Father) will come back
    DD TP | | MF SS
    M DD TP | | F SS
    5. Police and thief will go and stay and father will come back
    M DD | | TP F SS
    DD FM | | TP SS
    6. Father and mother will go and mother will come back
    DD | | MF TP SS
    MD D | | F TP SS
    7. Mother will pick one girl to other side, this time police and thief will come back
    D | | MD F SS TP
    T PD | | MD F SS
    8. police take remaining girl to other side, police will come back.
    T | | PD MD F SS
    PT | | D MD F SS
    9. Police will take thief other side.
    — | | PT M DD F SS


    This solution has another solution for that we just need interchange father with mother and boy with girl
    Happy journey ends
