Thanks to KrazyDad I am still working through a lot of print outs of the Penrose Slitherlink variant. Now KrazyDad has another addictive and more difficult version created of Slitherlink.
It’s called Altair Slitherlink and is based on the medieval Islamic tiling. The pattern contains tiles with 4,5,6,7 and 8 sides, which makes the puzzle a little more interesting than my previous Slitherlinks, which only use tiles with four sides. You can preview some sample puzzles by downloading this PDF file and printing it at the KrazyDad website. This is an interesting variant as you have to find new ways to solve this kind of Slitherlink puzzles. Happy Puzzling!
