About Waajji
A studio that tests social science with playful products.
Waajji is a studio of social behaviorists, economists, game designers, and philosophers. We build playful things that test social science — because people are most honest when they are playing, and a finding is most useful when it is playable.
The studio
Waajji began in 2025 with four chairs and one argument. A sociologist said people could be understood. An economist said they could be priced. A game designer said they could be designed for. A philosopher asked what any of it meant. The argument never ended — it just moved into a workshop, and the workshop started making things.
That is the studio's method: take a question about people and operationalize it — turn a theory that cannot be asked into a situation that can be played. Each product is a small field experiment, and everyone who plays it is a collaborator — because in the social sciences, the observer is always part of the observation.
Products as social instruments
We design network tools that make people behave like themselves — curious, tangible, and a little strange on purpose.
The homepage introduces two working principles; all four are collected here.

Questions, answered plainly
Quick answers before the deeper reading.
What exactly does Waajji make?+
Network projects under Team Wik20 — Investment Lesson, DeckX, and Duck Derby. Everything is designed as a small social experiment you can use.
What does 'sociological products' mean?+
Products designed to test how people behave — how they gather, trade, play, bluff, and make meaning. We believe a good hypothesis about people should be something you can play. The product is the experiment; the users are the data; the fun is the point.
Who is behind Waajji?+
A team of social behaviorists, economists, game developers, and philosophers, founded in 2025. Team Wik20 ships the studio's network projects.
Is Waajji a company or a collective?+
A registered company — 哇嘰網路科技有限公司 — that works like a studio. We use the name Waajji everywhere publicly.
Are the projects free to use?+
The ones that are live are open: Investment Lesson's core stages are free. DeckX is in open testing — sit at the table on waajiigames.com if you want to try it. Duck Derby is still in development.
How can I collaborate or get in touch?+
Write to hello@waajji.com. Collaborations, press, and curious inquiries are all welcome.
