PLAY THE GAMES

SELECT LEVEL

🏠
LEVEL 01

The Housing Project

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

PLAY
💵
LEVEL 02

The Budgeting Project

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

PLAY
🧾
LEVEL 03

The Tax Project

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

PLAY
🚗
LEVEL 04

The Car Project

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

PLAY
LEVEL 05

Four Weeks

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

PLAY
🔧
LEVEL 06

The Emergency Project

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

PLAY
✉️
LEVEL 07

The Offer Letters

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

PLAY
❄️
LEVEL 08

Snowball Derby

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

PLAY
🔦
LEVEL 09

Sign Here

A landlord, a lease, and traps written in invisible ink. Find them with the UV light — then negotiate them out.

PLAY
📱
LEVEL 10

Scam Slam

An inbox full of scams and a few real messages. Swipe fast, read the red flags, and keep your identity attached.

PLAY
🫠
LEVEL 11

Subscription Creep

Every forgotten free trial feeds the blob. Cancel the zombies, dodge the dark patterns, and starve the Creep.

PLAY
🥚
LEVEL 12

Score Pet

Your credit score is a creature. Feed it on-time payments for three years and raise it from egg to dragon.
