MindtheGrid

Every station you place in a daily grid is collected and lights up. Practice grids don't count.

Tap a station to see it. Drag to move, pinch or scroll to zoom.

How the clues work

First time? .

The basics

Every square needs a station that fits both its row clue and its column clue.
Any Tube, London Overground or Elizabeth line station with a TfL fare zone can be an answer.
Name clues use the official station name. Capitals and punctuation don't matter.
A wrong guess uses up a guess. Unknown names and stations you've already placed don't.
Tap any clue on the grid to see its rule.

Rarity score

When a grid ends, each answer shows how common it is, as a percentage of all the stations that fit that square.
It's based on how many people use each station a year (TfL figures). A busy station like Waterloo scores high; a quiet one scores low.
Your rarity score adds up all nine squares, and an empty square counts as 100. Lower is better, so lesser-known stations win.

Puzzles

Themed grids picked by MindTheGrid, just for fun. They don't count towards your stats, streak or map.

How puzzles are different

Specific answers. Every square must also fit the puzzle's theme, so some squares have only one or two stations that work.
You can clear a square. Stuck? Tap a filled square and choose Clear this square.
No guess limit. Keep trying until every square is filled.

Make your own grid

Pick three row clues and three column clues. Every square needs at least three stations that fit, and the grid has to be solvable with nine different stations.

Custom grids don't add stations to your map. Only the daily grid does.

About MindtheGrid

Hi, I'm Jack. I moved to London in 2025. I love city-building and transport games, so naturally I fell for the complexity of the London transport network. MindtheGrid is purely a hobby project.

The game

Every day there's a new 3×3 grid. Find a London station that fits each square's row and column, with nine guesses to fill all nine squares. Every station you place is collected on your map, so the more you play, the more of London lights up.

Support the game

MindtheGrid is free, with no ads. If you enjoy it, you can buy me a coffee. It all goes back into keeping MindtheGrid running.
