A sunday afternoon brain teaser

See if you can solve this puzzle. Moving only three pennies can you flip this triangle upside down?


If you are having problems try using real pennies

  • Move the very top penny and put it at the very bottom to make it pointy. Then you take both ends(left & right) at the bottom and put it beside the two pennies at the top.

    THERE YOU GO! AN UPSIDE DOWN PYRAMID!

    hehe...that puzzle was on one of the smarties box...

  • I got the answer. Mr.Reece! Well you have to add the last two from the four pennies at the bottom. Then add it to the row that has two pennies, which makes that row have four pennies. Then place the one penny at the top to the bottom.

  • (top row=first row, bottom row=fourth row)

    1. first row, penny -> very right, next row
    2. fourth row,first penny -> very left, third row
    3. fourth row, last penny -> fifth row

    its hard to explain....

  • Move one of the bottom corner pennies to beside one of the rows that has two pennies. then get the other penny thats in the bottom corner and then move it to the other side of the row that you put the other penny to.then take the top penny and then put it under the remaining two pennies at the bottom.
