Oh goodie, ranked pay-to-win events now. If you don't pay, you're below the players who do, and can't get the good prizes. Other than that, it's a typical mobile tycoon game, built around brain-addictive Dark Patterns and ridiculously unbalanced prices (first cell might be $2000, last cell in the same set might be half a million). I've been stuck waiting for $200,000 for the next thing I can buy, with an income of $1500 -- go play the real Prison Architect, it's this minus the manipulation.
