Ten minutes. Earn as much money as you can before the bell. Your score is the total you earned, not what is left in the bank.
Collect. Each business fills a bar. When it is full, tap it to bank the money. Keys 1-9 and 0 collect too.
Open and grow. Spend your cash on more copies of a business, or open the next one. Use x1, x10, x100 or MAX to buy in bulk.
Milestones. Every business doubles its output at 10, 25, 50, 100 and more copies. Watch for the x2 flash.
Managers. Hire a Bot to run a business for you. It collects and restarts on its own, so you never have to tap it again.
Modes. Classic is the ten minute sprint. Daily gives everyone the same twist, one business pays double, with its own board. Zen has no clock, no board and no trophies.
Pause. Press P or Esc, or tap the pause button. The game also pauses if you switch away.
