    For me, the coolest part is that by doing this puzzle you build a "perfect" hexagon with the coins!

    You say there is only one rule - the coin you move must be touching two other coins when you're done moving it. If that were the case, I could move three coins at once and have a hexagon in 1 move without breaking that rule. However, there are

    This puzzle isn't that difficult but he's totally right about that forgetting thing. When I looked at the screen I solved it in about a minute in my head. After getting some coins to make sure I was right, I already forgot the solution and had to solve it again :D
