Building a monopoly (in real life and on the board game) takes a long time. If you're interested in speeding things up, try one of these shorter Monopoly game options:
Timed game: Players decide on a time limit before the game begins. The Title Card deck is shuffled and the Banker deals two cards to each player. Players immediately pay the Bank for the value of these properties. When time is up, the player with the highest asset value is the winner.
Short game: Players set up the game normally, with the following exceptions: The Title Card deck is shuffled and the Banker deals two cards to each player. Players immediately pay the Bank for the value of the properties. Building Hotels requires three houses instead of four. When the second player is declared bankrupt, the game ends, and the wealthiest player is the winner.
Speed Die: This gameplay is only available on newer Monopoly sets that contain a special Speed Die. The Bank distributes players an extra $1,000 during setup. Players move around the board normally until they pass Go for the first time; Afterward, they roll the Speed Die with the two dice.
If players roll a 1, 2 or 3 on the Speed Die, they add this count to the number of moves they rolled on the other dice and move that many spaces.
If they roll the Bus, they can choose their move: either the value of one regular die, the other die or the sum of both dice.
If they roll Mr. Monopoly, they move their token based on the sum of the two normal dice and complete their turn. Then, if the Bank still holds property, the player must move their token to the next available property on the board and either buy or auction it.
If the Bank does not hold property, the player moves their token to the next property that will require they pay rent to another player.
