This game is part of the Journal’s “The New Rules of Money” package about the financial challenges facing young adults.

Navigating life’s financial decisions can be hard.

This is the game of your nest egg. Help guide it through 10 financial milestones: Will you rent a home or buy? Stay single or get married? Have kids or get a puppy? Each step can grow or shrink your nest egg. The goal is to make it through without getting fried.

We want to put you in the shoes of a young(ish) person, so you’ll be graduating college in 2010 at the age of 22. The numbers in this game come from the Bureau of Labor Statistics, the Federal Reserve Bank of New York, the Census Bureau and the National Center for Education Statistics. All figures have been adjusted to 2010 dollars. (See our methodology at the end for FAQ.)

And remember, this is a game, so your options are more limited for egg life than in actual life. For real life financial planning, here’s an actual retirement calculator for humans.
