Ahh the strange and quirky world of hidden object games, where paper clips are the size of watermelons, photographs come in little torn up pieces, and there’s no crime that can’t be solved by collecting a garbage truck’s worth of junk. But there are important things to be learned from HOGs too:

Most libraries/museums are kept in horrible disrepair, but librarians/curators will happily let you take priceless antiques in exchange for some light cleaning.

Mainstream science hasn’t conquered time travel, but your eccentric uncle (or grandfather) has.

You can never just walk through a door. First you have to find the key, which is kept in a small chest that’s kept in a locked safe inside a locked closet in a locked study that’s down a blocked hallway on the second floor of a locked house.

If you stumble into a village that’s been abandoned/closed up for the winter, don’t feel shy about breaking into houses, barns, and places of business. The locals won’t mind!

Exterminators must have nerves of steel, because not only are bugs everywhere, but some of them are the size of cars.

Lighthouses are generally powered by a series of mirrors, candles, and bits of string that must all be placed in EXACTLY the right way.

Police don’t solve crimes; journalists do.

You’re only permitted to check into a hotel after you’ve found 10 room keys, a banana, 3 spiders and the Eiffel tower.

That big vat of acid (that I dip into with my bare hands to fill a beaker) doesn’t hurt my hands at all, but watch what it does to that old rusty chain!

If your aunt lets you use her vacation home while she’s out of town, turn her offer down.
