Mob March
Multiply the mob. Storm the castle.
An endless crowd runner. Fire runners from a cannon through gates that multiply them, dodge traps, and storm enemy castles section after section. Built-in ads, five upgrade paths and art drawn entirely in code. Ready to run on Android, iOS and Web.
Watch It in Action
Turn a Few Runners Into an Army
Every runner you fire can become a crowd. Blue gates multiply it, red gates cut it down, and the castle at the end of each track falls to the bigger mob. It never ends, and it gets tougher every section.
Gates That Multiply
+N and ×N gates grow the mob, golden gates burst into a whole crowd, and red −N and ÷N gates thin it out.
Castles That Fight Back
Enemies march down from the castle. Each one that reaches the cannon chips its shield, and the run ends when it breaks.
Always Something to Upgrade
Coins from every run buy Cannon, People, Luck, Speed and Income upgrades, each up to level 999.

Built for Big, Satisfying Runs
Every section is new, and every run pushes a little further.
Endless Sections
Generated from a seed and harder as you go, with a fortress full of giants every fifth section.
Gates of Every Kind
Moving and shifting gates, golden gates, and red gates that subtract or divide your mob.
Hazards and Enemies
Saws, crushers, walls that tanks smash, pits, sweepers, lasers, enemy squads and giants.
Five Upgrade Paths
Cannon, People, Luck, Speed and Income to level 999, plus coins earned while you are away.
Castles That Topple
The castle is drawn in 3D blocks and collapses into rubble when your mob breaks through.
Fast and Juicy
Up to 1000 people on screen at 60 FPS, with screen shake, particles, sound, music and haptics.
From Cannon to Castle
Aim and Fire
Hold and drag to aim the cannon and fire runners up the track. Auto-fire can be turned on in Settings.
Multiply the Mob
Steer the stream through blue gates to grow your crowd.
Dodge the Traps
Avoid red gates, saws, crushers and lasers that cut your mob down.
Storm the Castle
Bring the castle down, then march on to the next, harder section.
Upgrade and Go Again
Spend coins on upgrades and push further on the next run.

Project Details
Mob March, Answered
Is the source code really free?
Yes. You download the complete Flutter project at no cost.
Does it run without changes?
Yes. Run flutter pub get, then flutter run for Android or iOS, or flutter run -d chrome for the web. It ships with Google test ad IDs, so test ads show straight away.
Do I need to replace any images?
No. Every character, gate, hazard and castle is drawn in code from the colours in brand_config.dart, so changing the colours reskins the whole game.
How do I add my own ads?
Put your AdMob app ID in the Android manifest and iOS Info.plist, your unit IDs and AdSense publisher ID in brand_config.dart, and your AdSense tag and ads.txt line in the web/ folder.
Does the game ever end?
No. Sections are generated endlessly and get harder, with a fortress every fifth section. A run ends when the cannon's shield breaks, with one revive per run.
