So I logged back into my Monopoly City Streets account to confirm what I suspected and I wasn’t disappointed. The leaderboard was dominated by people with hundreds of trillions of dollars. I’m absolutely amazed this is what Hasbro and Google had envisioned for this game. It seems ridiculous that they didn’t know this was going to happen. Basically when you start the game you have something like $1,000,000. You can then buy streets and start another account. This secondary account can purchase the street you just bought for twice as much as you just paid for it. Thus your second account is drained but your primary account has just flipped its property instantly for much more than its worth.
The very day this came out I tried this once to confirm it was possible because I thought maybe they would have included some safeguards to prevent this like many MMORPGs have done in the past. Once I realized it was possible I knew that anyone who wanted to win would just be programming a bot to perform this process over and over again and sure enough within 24 hours (before money was distributed even, since its only every 24 hours that you get money from rent, etc) people had billions of dollars which is impossible without cheating with multiple accounts. What a huge waste of time and energy that game is.
