Don't take our word for it โ try a real question
This is how Tandio teaches: not "pick the right answer", but live through the consequences.
๐
ฟ๏ธ
One parking spot left in the mall garage.
You're coming from the left, another car from the right, and you both spot it at the same moment. Neither of you knows what the other intends to do.
What do you do?
๐ก None of the three outcomes was yours alone โ each depended on what the other driver did at the same moment. That is what separates a game from a solo decision.
Built like a game. Serious like a textbook.
Every mechanic in Tandio exists to make you come back tomorrow โ and understand a little more each time.
Learn by deciding
No "guess the right answer". You choose, an opponent responds, and the outcome plays out โ that's what strategy actually feels like.
7 ways to interact

Review before you forget

Questions? Answers.
Is Tandio really free?
Yes โ you can learn the full game theory course for free. A heart system limits how many mistakes you can make in a row; wait for them to refill, watch a short opt-in ad, or upgrade to a subscription for unlimited hearts. No paywalled lessons.
Which devices are supported?
Tandio runs on iPhone and Android phones. Your progress, gems and streaks sync to your account, so you can switch devices without losing a day.
Do I need any economics background?
None at all. The first lesson starts from a parking lot standoff and builds up from there. Everyday scenarios first, jargon second โ and every term gets defined the moment it appears.
What exactly will I learn?
Game theory: what makes something a game, the prisoner's dilemma, dominant strategies, Nash equilibrium, coordination, mixed strategies, repeated and sequential games, credible threats, signalling, auctions, public goods and bargaining โ each grounded in a real case study. Microeconomics: scarcity, choice, opportunity cost and more, with AP-style practice questions.
Can I use it in Chinese?
Yes. Tandio is fully bilingual in English and ไธญๆ. Switch in settings anytime โ lessons, scenarios, narration and case studies are all translated.
Who is behind Tandio?
Tandio is built by NorthForge, a small independent team that believes strategic thinking is the most underrated life skill โ and that the best way to learn it is to play. Questions or feedback? hello@tandio.app
