Four hidden slots. Six symbols. Six probes. Tap symbols to fill the four slots, then PROBE. You get back two numbers and nothing else: how many symbols are in exactly the right place (green), and how many are the right symbol in the wrong place (amber). Never which ones. LOCK a slot you think you've worked out. Right — it's confirmed and fixed for the run, and it scores. Wrong — it costs you a probe. Locking all four correctly is solving the code. Everyone in the world gets the same code each day.

Patrons order; the clipboard is the law. SERVE legal patrons to earn their tab. DENY rule-breakers for a security bonus. Serving a rule-breaker = compliance strike (3 = impound). Wrongly denying a legal patron costs a fine, and slow service loses the sale. Bank 350 CR by the end of Day 3 to keep your lease. Keyboard: SPACE serves, X denies.
