This puzzle I created for the practice of US Puzzle Championship 2009. Fences puzzle (also known as "Slither Links" or "Loop a Loop" ) is one of my favorite puzzle. This is very nice variation on this puzzle type. As this is my second puzzle of this type. This is an easy puzzle. However my first puzzle of this type is even easier and is published in Mini Puzzles Series with title Wolves and Sheep in Fences (Mini Puzzles Series #16) and this Wolves and Sheep in Fences puzzle I am publishing as 10th puzzle in Logical Puzzles Series.
