Monopoly Streets

The method above did not work very well for me. I figured out a way to set the rules and it worked on my first try.

Begin by creating a custom set of rules. I'm going to only list the rules I changed, all the others will be on their default setting because I found no need to change them.

Game Setup Rules
Starting Cash: 2500
Starting Properties: N/A
Starting Property Distribution: N/A
Auction Timer: 10 (But maybe more if you're not a quick thinker
Use Speed Die: On

Gameplay Rules
Just change "Always Auction" to "On"
Everything else should be fine on it's default settings

Board and Property Rules
Salary for Passing GO: 500
Double Salary for landing on GO: On

Game Ending Rules
Win Condition: Most Color Groups
When # Players Bankrupt: All Others
Game Ends in # Turns: Off
When # Color Groups Acquired: 1
When a player has # Total Worth: Off

Now once the game starts it doesn't matter what order you are because the properties will always be auction off no matter who lands on it.

The winning condition is acquiring 2 color groups. I personally when for the Utilities (as the computer will put down relatively low bets on these properties) and then got lucky and acquired the Brown properties. This took me less that 5 minutes to accomplish. However, you should figure out and strategize your approach and adjust accordingly as the game progresses.

Just remember that if it's not a color group you're going for make the computer pay as much for it as possible and also watch out for one of the CPU players to try and snag a color group early on as should you.

So I think that is all pretty clear, this is my first solution post so if anything is unclear find me on XBL and I'll explain it more.

NOTE: XxChiCubs32xX posted in the comments below that he/she accidently put it on one color group to win; I don't remember being able to do this but if it is possible then definitely do it as it will shortin the length of the game.

UPDATE: It has been confirmed that XxChiCubs32xX was right and you can set the game to one color group.

This is by no means a "surefire" way, but it gives a good chance of winning against 3 Hard AI.

Play a Bull Market game and set all three AI to Hard. A Bull Market game ends after 20 rounds.

Make sure you win the toss to start first. If not, quit and restart.

This game mode will begin with forced auctions on ALL properties, as oppose to official game rules. Concentrate on bidding only on the following color groups (in order of importance):

- light blue
- pink
- brown

Ignore all other properties. Try to keep at least $850 with you though. If you don't have enough to keep $850, forgo the brown properties.

During the bidding, try to trick the AI into paying more for other properties even if you don't want them. Do so by bidding close to the leading bidder, and then lowering your bid at the last minute. This is to make them spend more and lower their cash flow.

Since you're the first to throw the dice, do so, and upon completing the move, immediately build all the light blue properties into hotels with your $850.

With some luck, one or more AI may just land on your light blue properties, and start paying to you excessive rent. The AI are aggressive in auctions, and most, if not all of them should be left with very little money after the auctions, not helped by you tricking them into bidding more earlier. Landing on your light blue properties should force them to mortgage a few properties.

If you manage to bankrupt a player, all his/ her properties will belong to you, which increases your net worth.

Once you get rent from the light blue properties, build houses (and hotels if you've more money) on the pink properties. With some luck, the players who landed on light blue properties may even hit the pink ones, which should immediately bankrupt them. Continue to build on the brown houses once you're done with the pink.

Basically, as often as you get money, build houses and hotels on all your monopolies. The more you build, the higher the chances that the AI will land on them and pay you rent.

Obviously, this still has a lot to do with the luck of the dice, but as long as one player lands on your light blue properties, you should have a healthy net worth lead that should help you hold on for 20 rounds.

I managed to bankrupt two players (one of them bankrupted on Turn 2 after landing on both my light blue and pink properties!) by Turn 8 doing the above, and rode all the way to the 20th turn with a $4,000+ lead on net worth over the last AI to win the game easily.

Alternatively, you may want to just hold on to the hotels of the three color groups, and not build anymore. This is in case you get hit by a Chance/ Community Chest card that requires you to pay maintenance on your houses and hotels. Even without additional houses and hotels, you should be able to ride out 20 rounds.

If you've more tips, please comment and I'll add them in.

One more thing that I forgot to add earlier: after bankrupting an AI and taking over his/ her properties, another AI may initiate a trade to try to form a monopoly for him/ herself. You know what to do... blatantly refuse! :)

I literally just did this, I didn't even think it'd work but I popped the achievement!

EASY WAY!!!

IMPORTANT: 4 CONTROLLERS AND SECONDARY PROFILES REQUIRED, you can simply use "Player1" type profiles they don't have to be Xbox Live Silver/Gold.

So let's get started shall we? First, setting up the rules.

Step 1: Rules

I was using a Custom Game build from another solution so here's that build:

I set up a custom speed die game for mine with speed die turned on for the start, also turned off all tax so you dont have to pay anything and made get out of jail free to, also you want to start off with all properties delt out

once you start the game you want to mortgage everything so you can keep going round and round the board without accidently running out of money.

(Credit to angelicdevil88, )

Then I modified it for the Tax achievement, simply turning Tax on to the maximum under custom rules.

NOTE: If you wish, you can also modify how many houses and hotels are allowed maximum (to bankrupt the other players faster).

Step 2: Setting up for Victory

Now, what you want to do is make sure ALL 4 CONTROLLERS have a profile signed into them. Start up the game, roll your dice...trade all the properties that belong to each individual player to the main profile (in return from the main profile, just give them "$1"). After all properties belong to the main profile, wait until the game saves and then back out of it.

User sspeakeasy has this to say:

Step 3: The Good Stuff

Sign out Each Profile from the extra controllers EXCEPT the main one. You do not need to disconnect any controllers, but you MUST sign out the profiles otherwise the game will load you back up with human players.

This will force the game to place AI players in for the now unavailable players when you reload your save game (as the warning says). Apparently, these players are set to Hard (as I unlocked my achievement at the end of this run) but basically here's what you do from here:

Step 4: Mopup other Achievements or Go Straight for the Gold

Option A:

If you're going for ANY other achievements (luck based ones like Three Triples, Rolled a 15, etc.) MORTGAGE ALL OF YOUR PROPERTIES and just keep rolling the die until you pop what you need (including the Jail ones, make sure to pay attention if you get into Jail to get those Doubles to get out). Along the way if you get a BUS, use that to move yourself either into Jail or into the Tax section (so you can work on the 1200 TAX achievement).

Option B:

If all you need is this achievement, Add Hotels to whatever properties you want and then houses to the remaining properties. Now, just roll the dice whenever your controller vibrates and let the game play out automatically. There's no way you're lose (unless you're highly unlucky and somehow end up paying so much tax out of your ass that you do bankrupt yourself) and they'll all gradually become bankrupt themselves.

After the last player bankrupts, achievement unlocks! If you followed sspeakeasy's suggestion, then each player will become bankrupt after one turn each (as they'll most likely land on one of your properties) so the Hotels won't be needed.

=) I hope this works for everyone else, I honestly wasn't expecting it and was just doing a test run but it sure as hell worked! GOOD LUCK!
