The Gerrymander Game

One neighborhood of 25 homes. Blue holds the majority, 52% to 48%. Three challenges: rig the map, perfect the rig, then repair it. Pick a district color and click or drag across homes. Districts must be connected.

Blue · 52% Red · 48%

Pick a color → click or drag across homes → click a home again to clear it. Five connected homes per district.

Congratulations.

PackingCram the other side’s voters into a few districts they win overwhelmingly, so their extra votes count for nothing.
CrackingSplit whoever is left across many districts, so they fall just short in every one of them.
Wasted votesEvery vote in a losing district, and every vote past a majority in a winning one. Gerrymandering is the art of making the other side waste more.

Now you know how the lines work.

Real maps get drawn the same way, just with more people and higher stakes. Help us make the rules clearer for everyone.
