Tokencito, the game app to learn AI

How it plays

At the center of the game is a small system that misbehaves: an assistant that makes up answers, forgets what you told it or overspends. You save it in four steps:

• Predict: before running it, pick what you think will happen.
• Run: watch it answer and find out if you were right.
• Fix: change its instructions and watch it change in front of you.
• Apply: solve the same problem in a new context.

What you will learn

Three courses, for people who code and people who do not:

• Artificial intelligence, no code: what a token is, how a model predicts, what it costs, why it makes things up and how to fix it.
• Agents, for people who code: coding agents, subagents, skills and MCP, what they really do and what they only say they did.
• AI costs: why one model costs more than another, what effort is, and how to pay less without losing quality.

A few minutes a day

• Game of the day: up to five questions, the same for everyone. Share your squares without giving away the answers.
• Daily streak: every day you play adds up, and if it breaks you start again without losing anything.
• Review that comes back: what you miss or save returns spaced out, tomorrow, in 3 days and in a week.
• Guess the token: pick the word that comes next and see how a model decides.

Is it free?

The app is a free download and the basics are free forever: the first path of each course, the game of the day, your streak and review. Tokencito Complete opens everything else with a one-time purchase, no subscription. On the web you play the first session of each course.

No lives: mistakes do not punish you, you see the right answer and its explanation. No account: your progress stays on your phone. In English, Spanish and Portuguese, ages 16 and up.
