Play StrataContract

What you play

Tap a block to probe, support, mine or move. Open the cost ledger, rehearse cave-in risk, then return ore to the shaft. Gold outbound and teal return paths preview the selected plan; return cave-in warnings and unknown cells remain distinct. The top bar explicitly labels planned carry and preview carry; only real execution uses the carried-ore label. During execution, ore, work-hours and carried-ore counters now follow real progress. Planning and rehearsal remain estimates; delivery still requires an actual return to the shaft. Rotate on the same page while keeping the plan.

One mining order with a route plan, cost ledger, rehearsal and actual ore delivery to the shaft.

Controls

Select a block and choose probe, support, mine or move. Inspect the cost ledger, preview the plan, then execute the chosen route.

Your first session

  1. Plan how to reach the ore and how to return with it. Keep unknown cells separate from cells with a known cave-in risk.
  2. Use probe and support decisions to revise the route, then inspect the rehearsal rather than treating a planned carry count as delivered ore.
  3. Execute the route and return to the shaft. Watch the actual carried ore and work-hour counters during execution.

Decisions worth watching

Gold outbound and teal return paths are previews. A visible return line is not proof the route has been executed.

Ore carried inside the mine has not yet been delivered. The shaft return is part of the order.
