Taylor Family Disclosure: Taylor Family Software builds Invest-A-Gator, the game we recommend below. It’s free with no ads or microtransactions. We make money on our paid products (FlowLister, Black & Gold SEO) and keep the game free as a thing we believe in. The Buffett principles taught are real and well-documented; the recommendation to use Invest-A-Gator specifically is biased, disclosed.
You can read every Warren Buffett shareholder letter and still buy the wrong stocks. Knowing the principles isn’t the same as running them. Value investing is a mental loop, and loops are learned by repetition under pressure, not by reading.
That’s where games come in.
Quick answer: play Invest-A-Gator, a free 30-minute browser game that runs you through Buffett’s actual decision loop with deal cards, owner interviews, and three diligence checks. After 5 sessions you’ll feel the difference between price and value in your bones.
Why books don’t work for this
Books explain what value investing IS. They can’t make you DO it. The gap between knowing “demand a margin of safety” and actually walking away from a deal that looks great-on-the-surface is huge. Books don’t put you in the chair.
The same problem exists in every skill that’s mostly judgment under pressure:
- Pilots learn in simulators, not textbooks.
- Surgeons train on cadavers and standardized patients.
- Chess masters play thousands of games before they read theory.
Investing is no different. The principles fit on a postcard. The skill is everything else.
The mental loop you’re trying to internalize
Buffett’s actual mental process, the one he’s described across 60 years of letters and interviews, has five steps:
- Stay in your circle of competence. Only consider businesses you understand.
- Read the business, not the price. Look at owner earnings, moat, management, growth.
- Estimate intrinsic value. What’s the business actually worth, given those numbers?
- Demand a margin of safety. Buy at a price meaningfully below intrinsic value.
- Walk away easily. Most deals don’t pass. That’s fine. Fat pitch wins.
Each step has obvious traps. “Stay in your circle”, but what counts as competence? “Estimate intrinsic value”, using what multiple? “Margin of safety”, how big? The traps are where games help.
Why Invest-A-Gator teaches the loop
Invest-A-Gator, our free browser value-investing strategy game, drops you in Warren the alligator’s shoes. You start with $75,000 cash and 30 weeks. Every turn, you’re choosing between a real-feeling pile of small businesses on offer in six districts.
Each deal card gives you:
- A seller’s claim about their owner earnings
- A list of red flags and green flags
- An asking price
Your tools:
- Books diligence ($900), reveals real owner earnings vs. seller claim
- Moat diligence ($800), reveals durability, management quality, customer concentration
- Risk diligence ($700), reveals debt, capex, lease years, hidden risks
- Owner interview, ten questions, Trust/Press/Challenge each, Challenge requires evidence
After full diligence, the game shows you intrinsic value, margin of safety, and a verdict. You can buy at the recommended price, make a value bid (lower than asking), buy blind without diligence, or walk away.
Sound familiar? It should. It’s the Buffett loop, gamified. (For the full design rationale and the cognitive-science citations behind it, see our research report on how the game teaches real value investing.)
What you’ll feel after 5 sessions
Run 1: you’ll lose money. You’ll buy things that “looked great” because the seller’s energy was good. You’ll skip diligence to save $2,400 and watch a “great deal” turn out to have $80,000 of hidden lease commitments.
Run 2: you’ll over-correct. You’ll diligence everything, run out of cash, and miss the actual fat pitches.
Run 3: you’ll start filtering. You’ll skip half the deals on instinct because they’re outside your district focus. You’ll diligence selectively. You’ll start hearing seller tells in the interview answers.
Run 4: you’ll understand “fat pitch.” Walk past 20 deals. Pounce on one that’s structurally underpriced. Watch the cash flow compound.
Run 5: you’ll catch yourself thinking like Warren. Without trying.
That progression is exactly what 5 years of value investing reps would teach you, compressed into a few hours.
What the game won’t teach you
Important honesty: a 30-minute game doesn’t replace 30 years of practice. Specifically:
- Sector knowledge. The game’s sectors are simplified. Real value investing requires knowing your sectors deeply.
- Holding through volatility. A 30-week season is too short for the years-long holding periods that real value investing requires.
- Position sizing across a portfolio. The game leans toward concentration; real value investing requires nuance about how much to put in each idea.
- Tax and macro effects. Outside the game’s scope.
But the judgment loop, what to dig into, how much to pay, when to walk, is the part the game gets right.
Other games and tools to pair with it

The order: play Invest-A-Gator for the loop. Read the Buffett letters for principles in his words. Run paper portfolios for the long-hold experience. Build spreadsheets for the math.
FAQ
Is this for kids? Yes, and one of the most valuable things you can show a 14-year-old. The game has zero ads, zero microtransactions, no signup required, and teaches a real skill. We built it partly with that in mind.
I already invest. Will I learn anything? Probably yes if you mostly trade tickers. The owner-interview mechanic in particular will surface judgment habits you don’t realize you have.
What about index funds? We’re fans. Most people should index. Value investing is the alternative for the small fraction of people who genuinely enjoy reading businesses, can spend the time, and accept the discipline. The game is fun whether you intend to actually do this or not.
Is the game biased toward our products? Yes, it’s our game. We disclose that openly. The principles being taught (Buffett’s value loop) are real, well-documented, and applicable regardless of what tool you use to practice them.
Verdict
Books make value investing sound like a checklist. It isn’t. It’s a fast judgment loop that has to be wired in through practice. Games shorten that runway dramatically.
Start with Invest-A-Gator, free, no download, ~30 minutes. Five runs in, you’ll have a feel for value investing that no book could give you. Pair it with the Buffett letters and paper portfolios. After a few months you’ll know whether this is something you want to do for real money.
Either way, you’ll have learned something, and had fun doing it. That’s a rare combination.
