This grid contains 4 groups of 4. Each group is connected by something very specific.
Click / tap the squares to try put them in a group. If you click 4 squares that belong to a group,
you'll be asked to type in the connecting theme.
Continue until you've found all 4 groups and figured out the connection within each group!
WARNING This is a devilish one. You'll need to take multiple steps to solve it, IF YOU DARE! >:-)
