Anyone want to roughly calculate the odds of this actually happening?

The specific sequence of rolls has 5 doubles (which can only occur one way) and 4 unequal pairs (which can occur two ways). Each double has a 1/36 chance of happening while the unequal pairs have a 1/18 chance. So that's 1/36^5 * 1/18^4 = 1/6,347,497,291,776 or about 1.5 times ten to the minus thirteen. It's interesting that the last four digits of the denominator of the probability of the shortest game of Monopoly a…

Nice, thanks

And don’t forget that Player 2 most also pick an “advance to Boardwalk” card out of a shuffled deck.

0 in practice, who decides to buy nothing? And even if player one declines to buy, player two can buy it via the auction.

My sister often buys nothing. She has this weird idea that certain colors and utilities aren't worth buying. I beat her every time with my "buy literally everything" strategy.

My favorite monopoly games are those where the players have played together before, and agree on a set of custom rules to the game in advance, and are fast-paced. I remember having rules added like loans and interest, and effectively unlimited freedom to make deals with players. Deals logged on paper, loan interest measured in turns and percentages, so much...fun. Actual fun though.

A game like this can even go fast paced where the next player is making their turn while you're still interacting with the bank from your turn, while someone else is calculating interest.

Doesn't sound fun typing it out but it was a blast.

If you drop some presumptions about the players you can go even faster-- Player 1: Roll a 3, 5, 6, 8, 9, 11 or 12. Don't purchase, so it goes to auction. In auction player 2 buys for 100% of their cash. Player 2: Rolls a 4, lands on income tax. Game over.

You’d be surprised how few people know about the rule for auctioning property that is not purchased. I’m guessing most people learned to play without reading the actual rules. It’s just passed down by copying the actions of your older siblings.

Neat. The longest possible game is playing with family that don’t like or don’t know the rules and like to put money on free parking.

That's when you sneeze or find some other reason to bump the table hard enough to lose the places of all of the pieces. "Ooops, I guess we'll have to pick this game up later"

Be the banker, embezzle the hell out of the bank, never worry about making rent. Eventually you’ll be discovered: “Hey! You’re cheating!”

“Huh? I thought that’s what this game was about. Y’all started it with that Free Parking nonsense.”

If we say it’s nine rolls of two dice, and the probability of getting any particular pair of numbers in each roll is 1/36 (underestimate since we sometimes only care about the sum), then getting any specified sequence would be like (1/36)^9, around 1e-14. Of course then we’d have to get the gameplay right too

Well played! And this strategy is actually easy to execute.

The probability for executing this strategy is: P(3)+P(5)+P(6)+P(8)+P(9)+P(11)+P(12) * P(4).

Plug in the numbers from https://statweb.stanford.edu/~susan/courses/s60/split/node65...

(0.0556+0.1111+0.1389+0.1389+0.1111+0.0556+0.278)*0.0833 = 0.07407036

So 7.4%.

And the Player 1 has to get “Bank error in your favor, Collect $200" in their first turn, otherwise they will lack $50 to buy 5 houses in turn 2 (which I assume is significant in raising rent for Boardwalk to $1400)
