This July, The Aperiodical are running The Big Internet Math-Off. To guide you through this event, the Math-Off online sticker book is back.
Every day you visit this site, you will be given one imaginary pound of pocket money. You can use this imaginary money to buy packs of stickers, or you could save up and bid to take over the lease of one of region's sticker shops.

Instead, click the "Synchronise your sticker collection between devices" on your other device. If you have started collecting on this device but see this message, email stickerbook@mscroggs.co.uk and I can hopefully recover your stickers.
This is an Easter egg.
