How to play Guessamillion
Guessamillion is a daily guessing game where knowing roughly is enough, as long as you know how rough your guess is. You start each month with $1,000 of play money and try to grow it as large as you can.
The daily slip
Every day at midnight Eastern time, a new slip of seven questions opens. Everyone in the world gets the same seven questions that day, so you can compare results with friends. Each answer is a number: a height, a distance, a count, a speed.
The questions get harder as the slip goes on: two warm-ups, three medium questions, and two hard ones. You get 30 seconds to answer each question. If the clock runs out, you lose 10% of your net worth, so it pays to commit.
Three choices per question
- Your guess. Type the number you think is right. You can write 1.2k for 1,200 or 3m for 3,000,000.
- Your spread. This is how wide a range you want around your guess. If the true answer lands inside the range, you win.
- Your stake. How much of your net worth you put on the line: 10%, 25%, 50% or all of it.
The spreads and what they pay
A tight spread pays more because it's harder to hit. A win returns your stake times the payout; a miss loses your stake.
| Spread | Example range if you guess 1,000 | Pays | Profit on a win | Break-even hit rate |
|---|---|---|---|---|
| ±5% | 950 – 1,050 | 5× | 4× your stake | 20% |
| ±15% | 850 – 1,150 | 2.5× | 1.5× your stake | 40% |
| ±35% | 650 – 1,350 | 1.6× | 0.6× your stake | 62.5% |
| ±70% | 300 – 1,700 | 1.25× | 0.25× your stake | 80% |
The break-even hit rate is the share of the time you'd need to be right for a spread to pay off over many questions. A ±5% spread only needs to land one time in five to break even, which is why confident players love it. A ±70% spread is a safe harbor, but it only makes money if you're right four times out of five.
Stakes unlock as the questions get harder
The warm-ups allow up to 25% of your net worth. Medium questions allow up to 50%. Only the two hard questions at the end of the slip allow you to go all in. That keeps the opening low-stakes and saves the big swings for the finish.
How to think about a bet
Before you lock in, ask yourself one question: how likely is it that the true answer is within this range? Then compare that to the break-even rate in the table.
Say the question is "How tall is the Eiffel Tower?" and your gut says about 300 meters. If you'd bet you're within 15% about 60% of the time, the ±15% spread is a good bet, because 60% beats its 40% break-even. If you're only 30% sure, the ±35% spread might be wiser.
Sizing matters as much as picking. Betting theory has a classic rule for this, the Kelly criterion: bet the fraction (p × b − (1 − p)) ÷ b of your money, where p is your chance of winning and b is your profit multiple. In the Eiffel Tower example, p = 0.6 and b = 1.5, which suggests staking about a third of your net worth. Most players do well staking less than Kelly suggests, since everyone overestimates how sure they are.
Your money carries over all month
- Streak paycheck. Showing up pays $100 times your current streak, up to $3,000 a day. Miss a day and the streak starts over.
- Bailout. If you finish a day below $1,000, you're topped back up to $1,000 the next morning. Nobody stays broke.
- Monthly seasons. On the 1st of every month the Rich List resets and everyone starts again from $1,000.
- Head starts. The top three players when a season ends start the next month with $25,000, $10,000 and $5,000. The winner earns a permanent crown next to their name.
