About Sydneydoku
A new Sydney rail puzzle every day. Nine cells, nine clues, one rule: the rarer your stations, the better you score.
Sydneydoku is a daily 3×3 grid built on the Sydney Trains (T-lines) and Sydney Metro (M1) network. Every row and every column has a clue — a line, a region, a station feature, or a bit of wordplay — and each cell sits where a row clue and a column clue cross.
How to play
- Tap a cell and name a station that satisfies both its row clue and its column clue.
- Each station can be used only once across the grid.
- A correct answer scores that station's rarity (0.1–100) — obscure stations score less.
- A wrong guess adds an escalating penalty — 30 for your first mistake, 60 for your second, 100 each after that — and you can try that cell again.
- Lowest score wins. Reach 1300 and you're locked out, so guess carefully.
Say a cell's row clue is T4 and its column clue is Underground. Bondi Junction fits both — but so does a rarer station like Edgecliff, and the rarer your pick, the lower (better) your score.
Scoring
Your score starts at 900 and drops as you lock in correct answers. Wrong guesses add an escalating penalty — 30 for the first, 60 for the second, then 100 each — and once your score reaches 1300 you're locked out, so guess carefully. A perfect grid of nine obscure stations can score far lower than a perfect grid of nine common picks, so think rare, not just right.
Play, then share
Come back each day for a fresh grid. When you finish, copy your emoji result to share, and see how you stacked up against everyone else who played today.
