31/13 builds online educational games where students master real-world skills — one level at a time.
Navigate the real cost of finding a place to live — renting, buying, and everything hiding in the fine print.
PLAY →Earn, spend, save. Students run a monthly budget and learn what happens when the numbers don't add up.
PLAY →File a real 1040 from a W-2. Decode the boxes, find the refund, and see exactly where the money goes.
PLAY →Lease, buy new, or buy used — price all three and defend the choice on total cost, not the monthly payment.
PLAY →Survive a month on a tight income where time is a second currency. Every hour and every dollar is a choice.
PLAY →The transmission just died and you need the cash now. Weigh four ways to cover it — and what each one really costs.
PLAY →Custom educational games for schools, districts, and organizations. One developer, start to finish.
