How the bank, the market hall and the five games work.
Every guide describes one part of the arcade: the five tycoon games plus the three things they share — the bank with the current account and loans, the market hall where players trade with each other, and your private life, which has to be paid for out of what you earn.
The guides describe the rules. If you would rather first know what a game actually is, the overview of all games is the better starting point. Everything is free, without ads and without real money.
