A person is raking leaves out of a drain in the game DrainSim.
A generator powers a camera on a tripod next to a large hole in a yard.

A person in overalls holds a plunger and a broom, standing near a rushing stream with rocky terrain.

DrainSim puts you at the head of city flood management, transforming everyday drainage into a physics-driven adventure. Step into the shoes of a modern-day hero as you tackle rising waters, restore order to submerged streets, and strategically solve complex flooding scenarios. With realistic water mechanics and dynamic environments, each mission challenges your planning, timing, and problem-solving skills.

Equip yourself with a growing arsenal of tools, from shovels and rakes to powerful submersible pumps and generators. Assess each situation carefully, choose the right equipment, and adapt to changing conditions like day-night cycles, tricky terrain, and unpredictable water flow. Thoughtful preparation is key as you juggle multiple flood zones and work to restore the city’s safety efficiently.

Progress through increasingly challenging areas to unlock advanced gear and upgrades, enhancing your ability to manage larger and more complex floods. DrainSim delivers an engaging and immersive experience for players of all skill levels.
