This game is fairly simple in itself. The goal: make the previous poster regret ever wishing for what they wished for.

Corrupt a Wish goes like this: the first person makes a wish. The next person grants that wish but twists it up before wishing for something themselves.

Here's an example

Person 1: I wish for a cake.

Person 2: Granted, but the frosting is made of cement.
I wish for an apple.

Person 3: Granted, but it's full of maggots and worms.
I wish for (etc.)

I'll start off.
I wish for 99 mining
