Iso City Sandbox
freetoolonline.com Editorial TeamIso City Sandbox is a free browser isometric tile sandbox where you paint your own small diamond-grid city right in the browser tab.
There is no budget meter, no win condition, and no simulation running underneath - the map itself is the point, so you build for the look rather than to hit a goal.
Key features
- Pick a landscape tile from the side palette, then click or drag on the 7x7 diamond grid to place roads, water, and buildings.
- Right-click clears a cell; the game plays with mouse or touch and reads best on a wide screen so the tile palette stays visible.
- Your layout is encoded in the iframe URL hash, so you can bookmark a build or paste the link to share the exact city you made.
- No account and no install - the whole toy is about 480 KB the first time you press Play, then it loads from your browser cache.
Privacy and saving
Nothing is written to localStorage, so clearing the hash or refreshing the page resets the board to plain grass.
Play in fullscreen
Once the game has loaded, a Fullscreen button expands the play stage to fill the whole screen.
