Seven Hockey Pucks

Solution

There are several ways to solve this puzzle. Many of you sent in great graphic illustrations to your solutions - thank you!! We show them below to illustrate these types of solutions.

Way 1 - 2D Solutions.

Draw a triangle. Then from each of the three angles of the triangle draw a line to the opposite side of the triangle. Make sure that all the three lines intersect in one point. 

Now put the seven pucks on the next points:
-- three pucks - on the three corners (vertices) of the triangle;
-- three pucks - on the sides of the triangle where the lines drawn from the respective corner points cross these sides.
-- one puck - on the point where all the three internal lines cross.

In this way you'll have six rows of three pucks each, namely, the three sides of the triangle and the three internal lines.

Way 2 - 3D Solutions.

We've got two solutions of this type.

3D Solution by Neil Myska

This solution contains 6+1 rows of 3 pucks each. Nice improvement!


How about 7 pucks into 7 rows of three

3D Solution by Joe Wolfe

It contains exactly 6 rows of 3 Pucks each. Great trick!

Way 3 - Special Solution.

We've got just one solution of this type.

Special Solution by Nickolas Daskalou

This solution contains 6 horizontal rows (lanes) with 3 hockey pucks each. Clever quibble!



Also we got some solutions - both 2D and 3D - which either have more than seven pucks, or have less than six rows of three pucks each.
