“When you run out of money, you can quickly down a shot of JÄGERMEISTER for $100 credit.”
I’ve found me a new rule for playing Monopoly!
The only other rule we use is if you land ON Go, you get $500, not $200.
People, people. The Official rules, puhleeze. Do you think those masterminds, the Parker Brothers (actually Charles Darrow), wrote those things down for fun? Noooo. Free Parking is … Free Parking. You only play with the number of houses and hotels in the box.
Sheesh~! 
Monopoly has strategy? Why are you lying, you lying liar, you?
Roll the dice, move your man, buy properties, and it’s a matter of pure luck who gets a full set and can develop it, bringing ruin to the others. If you want strategy, play something like Chess or Hungry Hungry Hippos.
We played you get $400 for landing ON Go. And had the Free Parking jackpot, of course.
As the grandson of the HEAD of Parker Brothers Monopoly production for the boom years of the 60s, 70s, and up to the mid 80s, I feel I must weigh in here and agree with all of the correct people 
Housing shortages ARE Monopoly, and nothing shows it better than someone who buys up the purples, light blues, and other purples, and sets up 4 houses on each to prevent development on the big money properties. That’s a game well played.
Mmm…Monopoly.
We play with money on Free Parking rule too. As kids, we added you had to go around the board once before you bought property. Someone could get lucky and end up around the board on the second turn while someone else took many turns due to low roles and landing in jail.

Auction Monopoly: when someone lands on a property it goes up for auction and the high bidder gets the deed.
Auction is part of the actual rules for Monopoly! It saddens me when people claim there are no tactics to Monopoly, in every case this comes from people who have never played by the full official rules, or tried them once and then changed them. There is indeed a lot of randomness happening in a game of Monopoly, but due to the large number of random events the probabilities tend to even out and then the tactics takes over. The key tactic or skill being that of negotiation with the other players, a skill quite rare in other board games (diplomacy being the obvious exception).
If you ever do think “Monopoly ends far too quickly, how can we stretch the game out longer” do the check thing. (or play The Farming Game, which can easily last months)
One summer, my siblings and I did play with “checks,” instead of paying rent immediately. All accounts were settled when you passed Go (so instead of collecting $200, you got $200 - the amount you paid in checks that round + the amount you got from others in checks that round) the accounting was insane.
That was the same summer we also played moneyless monopoly a lot (as one of the siblings had some “difficulty” distinguishing between her money and the banks money).
But at least we don’t do the free parking thing … (though we also don’t auction off properties if the landing person doesn’t want them.)

But in the official version of Monopoly, the player who lands on the property has the option of buying it outright. Because this is what happens 99% of the time, the auction clause is an insignificant factor. In the version I described, all properties go up for auction.
Another rule we used to use was promissary notes. The notes had a face value and a 10% interest value. When you took out a note, you got the face value. To redeem the note, you had to pay the face value plus the interest value. And everytime you passed Go, you had to pay the interest values of any notes you had. To get a note you had to have collatoral. You could get up to $2000 by putting up your ‘salary’. After that you had to put up property with a mortgage value equal to the interest value you were borrowing.
