Monopoly Bankruptcy Rules: What Happens When You Can't Pay

You go bankrupt in Monopoly when you owe more than everything you own is worth, and not a moment earlier. Cash, buildings at their sell-back value, and the mortgage value of your properties all count toward what you can raise. If the total covers the debt, you're not bankrupt. You're just about to be very busy.

The rule most tables get wrong

Owing more money than you're holding is not bankruptcy. It's a liquidity problem, and the rulebook expects you to solve it: sell buildings back to the bank, mortgage what you own, trade with anyone willing to deal.

Bankruptcy arrives only when the arithmetic runs out. Our engine calculates it the same way every time: cash, plus the sell-back value of every building you own, plus half the printed price of every property you haven't already mortgaged. Below the debt, you're out immediately, because there's no sequence of moves that saves you. Above it, the game opens a 60-second window and hands you the controls.

That window gets used. Players have opened 11,859 debt windows on our servers, and 9,921 of them closed with the debt paid instead of a player leaving the table.

What you're expected to sell first

Sell buildings before you mortgage anything. Two reasons, one of them a rule and one of them arithmetic.

The rule: a property can't be mortgaged while any property you own in the same colour group carries buildings. Try it in the wrong order and the move gets rejected. The full set of building rules, including what a house costs to put up and to take down, is in our houses and hotels guide.

The arithmetic: the official rulebook buys buildings back at half price, so demolishing is the expensive way to raise money and mortgaging is the cheap one. We pay building sell-backs at full cost in classic games, which softens the blow, but the order still holds.

After buildings and mortgages, there's one lever left. Someone at the table wants what you own, and a bad trade beats elimination every time. Our trading guide covers what a desperate seller can still extract.

Where your property goes

Two different endings, depending on who you owe.

Pay a player, and everything you have goes to that player: cash first, then every property you own. Under the official rules your buildings go back to the bank at half price and the money follows your creditor, and any mortgaged property transfers with its debt attached, so the new owner immediately pays the bank 10 percent interest on it. They can then lift the mortgage or sit on it and pay the interest again later.

Pay the bank, and the bank takes the lot and auctions every property, one at a time, with no reserve. That auction is where the rest of the table gets rich, and it's the moment a two-player race turns into a rout.

Our version simplifies the creditor case: buildings come down, mortgages are cleared, and the properties arrive in your creditor's hands ready to use. No interest, no paperwork. Bankruptcy to the bank returns everything to the unowned pool, where the next player to land on a street can buy it at the printed price.

The split is close to even in practice. Of 3,647 eliminations recorded across our games, 1,838 went to the bank and 1,809 went to a player.

Bankruptcy isn't always the end of the game

In a two-player game it is, and the survivor wins on the spot. With three or more, the game keeps going and your exit sets your final place: first player out finishes last, and everyone still solvent when the last opponent falls is ranked by what they had left.

1,366 of our 1,377 full-length games ended with at least one bankruptcy, which sounds obvious until you notice the other 11. Games can also end when a player surrenders, when the clock runs the table out of time, or when everyone but one player has already walked away.

When the first bankruptcy lands

Bankruptcy is the normal ending here. It is not the rare disaster a family game makes it look like, it is how nearly every finished game ends, and it arrives earlier than players expect: the median elimination happens in round 34, and 1,099 of the 3,647 we have recorded came before round 20.

Count them by table size and the arithmetic is brutally simple.

The pattern is exact. Everyone except the winner goes broke, so at a four-player table the question is never whether you can avoid the debt window, it is whether you can open it later than the other three. 1,480 players did not wait to find out and pressed surrender instead.

How to stay out of the 60 seconds

Rent you can't see coming is what kills you, so count the board before you spend. A player with three houses on an orange street charges 5,500. If your cash after building drops below the biggest rent in front of you, you didn't buy a house, you bought a coin flip.

Keep a lap of rent in reserve. Mortgage early rather than late, because mortgaging under pressure costs you the same 50 percent but with none of the choice. And when someone offers you a bad trade while you're sitting on 200 in cash, take the bad trade.

The players who survive the longest are the ones who never let the window open. Try it yourself in the lobby, where the timer is real and the rent is due whether you're ready or not.
