The Weekly Hunt is similar to the Daily Challenge, except, as the name suggests, it takes place over the course of a week. For every edition of Subway Surfers: World Tour, there are four Weekly Hunts. To complete the Hunt, you must find a certain number of Tokens to receive a reward.
The Tokens are specific to each edition, with New Orleans featuring Pumpkin tokens, while Tokyo used Japanese keychains for the collecting purpose. They are usually harder to come across than the Daily Challenge tokens, largely because you have a week to get them rather than just one day.
The Weekly Hunts began following the Rome edition and its Egg Hunt.
