Lucky box

A roulette in the style of in-game loot boxes that picks one of your games. You can choose between installed games or not, from which store, and whether it goes by hours played or (with ArlequinPro) by achievements: games you've never opened are the most likely to come up, and the ones you've played the most, the rarest.

You get 2 spins a day (5 with ArlequinPro).

"Forgotten" mode picks games you haven't opened in a long time; "Not this one" removes a game from the box, it doesn't repeat the latest prizes and it keeps your history. And if you take the challenge (play the game you got for 30 minutes), you win an extra spin, up to 3 a day. You can choose just your games or your Steam family's too.
