365 Seoul Challenge
Seoul turned everyday outdoor activities into personalised 16-square bingo cards, encouraging isolated residents to complete small challenges, share proof and earn local digital currency. The playful format gives a serious loneliness intervention an accessible hook, while brand partnerships add extra reasons to take part.
Why it worked: It reframed a heavy social issue as a gamified, incentivized habit loop—personalized bingo plus cashable points and early outcome data.
The lesson: Consider packaging a hard-to-sell behavior as a simple, customizable game with proof-based rewards and one striking pilot stat.
