BLOOD WATCH

You are at the registration desk. Check each candidate's ID, test slip and questionnaire; approve those who meet the rules and turn away the rest for today. The rules come from the Turkish Red Crescent's National Blood Guide, and new rules are added every morning.

Keep the stock, the budget and public trust standing for all seven days.

• Approve (→ key, or drag the card right): the candidate can give blood.
• Reject (← key, or drag left): the candidate cannot give blood today.
• Check records (space): opens any system record that contradicts the declaration, and costs 4 seconds.
• The rule book lies closed on the desk; click it (or press K) to open it, and pick sections with the tabs on the page edge. You can drag the documents around the desk to arrange them.
• The shift length is fixed and the queue never ends: every correct decision earns 10₺, every mistake costs trust. In the evening, meet the hospitals’ requests from your stock; at the end of the day you see your mistakes one by one.
