A new Sydney rail grid every day. Each row and column is a clue — a line, a region, a station feature, or a bit of wordplay.

• Fill each cell with a station that matches both its row clue and its column clue.
• Each station can be used once across the grid.
• A correct answer scores that station's rarity (0.1–100) — obscure stations score less.
• A wrong guess adds 100, and you can try that cell again.
• Lowest score wins. Reach 1300 and you're locked out, so guess carefully.

Tip: the obvious big interchange is rarely the low-scoring pick.
