One-Line Factory

Draw one continuous conveyor, route every parcel through 36 handcrafted boards, then keep the factory moving in an ever-tougher Endless Shift.

Draw one line. Run the shift. Watch every parcel find its way.

One-Line Factory is a compact logistics puzzle about planning one continuous conveyor from IN to OUT. Guide every parcel through its stations in order, then start the line and see whether your design can meet the quota before time runs out.

MASTER 36 HANDCRAFTED BOARDS

Six factory departments build on the rules one shift at a time. Route around blockers, obey one-way gates, balance limited belt tiles and tight corner budgets, use fast and slow cells, cross your own path with overpasses, and time shutters that open and close on their own rhythm.

COMPLETE, THEN OPTIMIZE

Solving a board is only the start. Rework your route to earn three independent stamps:

• Completion — deliver the full quota
• Compact — stay within the route target
• Express — beat the expert time

CLOCK ON FOR ENDLESS SHIFT

Unlock an ever-changing mode where each procedurally generated floor has a route to discover. Keep going as quotas, blockers, and the clock grow tougher from shift to shift.

DESIGNED FOR TOUCH

Draw with one finger and drag backward to erase. Start the conveyor whenever you are ready, watch the parcels move, then adjust your line and try again. Solver-backed hints can give you a nudge without solving the whole board for you.
