Cuddling Coins

The pattern of coins shown on the left must be transformed into the pattern shown on the right, by moving exactly three coins, where at the end of each move each coin needs to touch with at least two other coins. The coins must be moved flat on the table (coins cannot move over each other).



Answer: Move the three coins in the lower right corner together down and to the left.
