Format 1: the collect-and-complete campaign
Instead of a calendar with 24 doors, you build a collection that participants assemble piece by piece. Every purchase, website visit, or campaign action earns a new item. Completing the set is the pull.
This format works well for retail brands that want to incentivise transactions and for brands with a strong visual world. The driving force is ownership: you want to finish the collection, even if that takes multiple visits over several weeks.
We applied this mechanic in the HEMA Stapelgek campaign, where purchases were converted into stackable game cards. Return behaviour was measurably higher outside traditional seasonal peaks, proving the mechanic does not depend on the calendar window.
Format 2: the leaderboard with social pressure
Social pressure is one of the strongest return mechanisms available. People come back when others can see how they are doing, or when they want to see how others are performing.
A festive season leaderboard gives participants something to play for, something to share, and a reason to log in again tomorrow. It works best alongside a skill-based play element: a daily quiz, a mini game, a challenge where effort influences the outcome.
For JET Winter Winners, we built a seasonal campaign that combined exactly this: play, win, and share in a single flow, with the leaderboard creating organic return across the campaign window.
