Line Duty
Lead each unit to its gate
Free · Designed for iPad. Not verified for macOS.
One finger, four colours, five themes. Draw routes, dock units into their gates and never let them touch. No ads, no account, works offline.
Line Duty is a one-finger arcade about dispatching traffic. Units of four colours roll in from the top and drive down on their own. Draw a route for each one and lead it into the gate of its colour at the bottom. The line erases behind the unit as it goes, so the field stays readable no matter how many routes are running. Two units touching, a wrong gate or a unit drifting past the bases ends the run. Every delivery makes the traffic a little faster and a little denser.
HOW IT PLAYS
• DRAW AND DOCK. Drag a unit, draw its path, bring the line to its gate — the route docks and you can let go. A new line on a unit replaces the old one.
• COLOUR AND GLYPH. Circle, square, triangle and diamond on every unit and gate, so colour-blind players are never guessing.
• WARNINGS THAT MEAN SOMETHING. A red ring with "!" appears when two units get too close. One free continue per run.
• FASTER WITH EVERY DELIVERY. +10 points per unit. The more you deliver, the faster they go and the more often they appear.
FIVE THEMES
Metro (dark), City with turning buses and parking bays, Aquarium with fish, grottos and rising bubbles, Anthill with ants and mounds, Garden with ladybugs and leaves. Switch from the menu — the whole app recolours, and every theme has its own gates and animation.
BONUSES
Hexagons appear on the field — drive a unit through one. Freeze stops everyone for three seconds, Shield forgives one collision, ×2 doubles your points for ten seconds, Autopilot drives the unit to its gate.
NO STRINGS ATTACHED
No ads, no purchases, no account, no internet needed, nothing collected. Your run is saved when you leave and resumed from the menu. A five-step "How to play" on first launch, statistics with a reset, seven languages, iPhone and iPad.
A game for a queue or a coffee break — close it mid-run and pick it up later.
