Slither Link and variants

The aim of a Slither Link puzzle is to find a closed loop in a grid. Digits in the grid indicate how many edge pieces that are adjacent to a grid cell (from 0 to 3) belong to the loop. Well, that's the standard Slither Link, but our authors have been very inventive. Try lying loops, fat loops, 3D-loops, cryptic loops or loops with multiple personalities, and have fun!
