Oberon

JAM VERSION, EXTREMELY FAE TOUCHED

You are Dad. Through circumstances, you have been transported by the Fairy King Oberon to... somewhere unfamiliar.

You are to play a game for the pleasure of Oberon. Hide-and-seek. You have been given a magical item, the Hand of Glory, to help you play the game. You are seeking the Silver Frog, who has the ability to turn invisible. Use the Hand of Glory to find it, and mail it back to the Fairy King.

Raise the Hand of Glory to attract, drawing gold towards you.
Lower the Hand of Glory to reveal invisible, casting shadows of the unseen and revealing treasure.

The wager? Who gets to live the next year of your life. The Fairy King is feeling restless, and a few years as YOU tickles his fancy.

First to three wins. 
Good luck, Dad.
