You put 2 rows of five beside each other then take one from the bottom of each row and put them next to the second to last one. I hope i explained it clear enough

• Dude

That’s not it, keep trying.

• Alan

Put the coins in the shape of a pentagram (five-pointed star), with four coins in each line.

• Dude

No, that’s not it. Keep trying.

• Dude

No, that’s not it. Please keep trying.

spread out five coins in the shape of a pentagon.now link all the coins with a line. (that’s four lines to each coin) you will now have a star shaped figure and a smaller, upside-down pentagon at the center. now place the remaining coins at the ends of the smaller pentagon. and there you have it, the longest lines have four coins on them and there are five of them. example image below

• Yes, a pentagram. A five-pointed star satisfies the parameters set in the riddle, Dude. Alan had it right.

• Dude

Yes Alan, the five-pointed star works. The Dude had another answer, however.

You are today’s winner.
