How to play

Paint districts

Click or drag on the map to assign cells to the active district. Click a painted cell to erase it.

Switch districts

Use the colored swatches at the bottom or the ← → arrows to change which district you're drawing.

Stay connected

Every district must be a single connected region. Diagonal connections count.

Balance the sizes

All districts must be within 20% of each other in cell count.

Score

Once every cell is assigned, hit score →. You're graded on gerrymander effectiveness (50 pts) and compactness via Polsby-Popper (50 pts).
