Album and swaps

The album has pages for the arcade, for each game, for each event and for the daily machines. An event's pages appear on the event's first day. Each sticker says what earns it, and it arrives by itself when you do it. Finishing a game, arcade or event page earns its title.

Every sticker has a number. No. 1 is the first copy anyone got.

The shelf has stickers you can buy with Credits. Some are only on sale for a short time.

Friends can swap stickers, one for one. A spare copy goes first. If you have no spare, the sticker leaves your album and goes to your friend. An offer waits in your friend's inbox for 7 days.
