Faultline Puzzle

Faultline is a geological survey logic puzzle inspired by classic mine deduction. Study seismic readings, mark hidden fault pockets with survey stakes, and clear every safe patch of ground. Survey Mode is the pure-logic daily challenge: every field is built to be solved by deduction, so careful play never needs a guess. Expedition Mode keeps the familiar higher-risk rules with first-clear safety and cascading open ground. Play the daily survey, build a clean-solve streak, unlock Unlimited for random fields and archive replay, replay the tutorial, and compare total or clean solves through Game Center.
