Games that make learning feel like playing.

31/13 builds online educational games where students master real-world skills — one level at a time.

SELECT LEVEL

Navigate the real cost of finding a place to live — renting, buying, and everything hiding in the fine print.

Earn, spend, save. Students run a monthly budget and learn what happens when the numbers don't add up.

File a real 1040 from a W-2. Decode the boxes, find the refund, and see exactly where the money goes.

Lease, buy new, or buy used — price all three and defend the choice on total cost, not the monthly payment.

Survive a month on a tight income where time is a second currency. Every hour and every dollar is a choice.

The transmission just died and you need the cash now. Weigh four ways to cover it — and what each one really costs.

Three job offers, one desk, twelve months. The biggest salary isn't always the best deal — the fine print knows why.

Race compound interest from 18 to 65. Start early, hold on through the crashes, and watch time beat money.
