Black boxes are point-producers. For every second that a team controls a box it produces one point for the team.
A player takes control of a zown by finding the box, getting the code, then texting the four digit code to the zown main number.
After taking control of a zown, a player can remain at the box to guard it from rival teams; if a player is guarding a box, rival players cannot capture it unless a greater number of players from another team approaches.
If a greater number of players from another team approaches a guarded box, the guarding player must cede control. Peacefully.
If two players are running to reach a box, the player who places his hand on the box first wins.
The team with the most points at the end of the game wins.
