I am by no means a mystery cache expert but I enjoy them very much. This Puzzle Gym series is intended as way for new cachers to build up their puzzle stamina and for the old timers to get in a bit of training to stop them becoming rusty. Please ask for help if you’re stuck, I want these to be solvable. Enjoy!

This sub-category is more of an umbrella term for caches which require you to perform mental gymnastics. This could be something that's quite straightforward in theory but which takes a lot of figuring out, but it could also be something which asks you to think sideways, backwards or anyway other than the way you expect. I am not very good at solving these, so there are not so many locally that I'm aware of. One good example is JoyChang's ㄈ口ㄗ丫ㄈ丹ヒ (GC7D3MA) and another is Haima's Dizzy (GC5D72H). With these puzzle anything goes but one good thing about this sort of cache is that once you've cracked the puzzle they often become face-palmingly easy to spot. Be prepared for red herrings and get your whole toolkit out.

I AM SORRY

Or create them.

They can change lives.

I AM PREGNANT.

They can cut us down.
