Take turns digging. Find a charge and you claim it and dig again; open a safe plot and the turn passes. The first surveyor to claim more than half of the charges takes the field.
A two-minute guided chart walks you through digging, pennants and clearing the ring.
The chart hides charges under some plots. Open every plot that isn't a charge and the area is clear. Dig a charge and the sector is lost.
An opened plot shows how many charges touch it: the eight plots around it. A plot with no charges nearby opens its whole neighbourhood for you.
Plant a pennant on a plot you know is a charge. When a number already has that many pennants around it, tap the number to clear the ring: every other plot around it opens in one go.
Your first dig is always safe. With fair fields on, every field can be finished by logic alone, so there is always a certain move. Hint shows it, and also spots a pennant on a plot that is provably safe. Sweeps finished with hints don't set best times.
Turn on question marks in Settings to mark plots you're unsure about. They don't count as pennants.
Each campaign sector awards three stars: one for clearing it, one for beating its par time, and one for a clean sweep with no hints, detectors or field kits.
One field per day, the same for every player. The landing zone is already opened. Clear it on consecutive days to build a streak.
Two surveyors take turns on one field. Dig a charge to claim it and go again; open a safe plot and the turn passes. Claim more than half of the charges to win.
