About

This interactive map reveals the spread of short-term rentals across the Municipality of Athens, based on real Airbnb data.

Each hexagon represents a walkable area, roughly a 3–4 minutes walking.

Just like in classic Minesweeper, your goal is to uncover all the safe zones without hitting a hotspot. Set your threshold, then click to explore.

Inspired by the Playable Data Lab project in Mallorca.

Threshold (mines)

New game

Airbnb histogram

Shows distribution of counts per cell. Vertical line is the threshold.

Rules

• Right click / long‑press: toggle flag.
• Number on a safe cell = how many “mines” (neighbors above threshold) around it (6 neighbors for hexes).
• Revealing a 0 cascades (flood‑fill).
• You win when all safe cells are revealed.
