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.
