What is House of Hazards?

Overview & Background

House of Hazards is an online platformer game developed by the game studio Japeal and originally published on CrazyGames.com. The game quickly developed popularity amongst players for its punishing difficulty and intense platforming challenges requiring fast reaction times.

As an unblocked game, House of Hazards spread as entertainment for people with internet access but limited gaming options, like students in schools or employees with spare time.

Gameplay & Levels

Navigating the Treacherous Tower Floor by Floor

House of Hazards gameplay revolves around navigating platforms and obstacles to traverse challenging one-screen rooms laid out floor by floor in a towering high rise gauntlet.

Armed with only the ability to run, jump, and climb ladders, you must safely make your way past the assortment of traps and enemies occupying each level. With smart movement, quick reaction times, and pixel-perfect jumps, it’s possible overcome the threats each room presents.


Players can run left or right across platforms and climb up and down ladders scattered around levels. By jumping, they can cross gaps, dodge hazards below, and reach higher platforms. Mastering movement and jumping accuracy is crucial to bypassing dangers.


Each level contains an arrangement of hazards that can instantly kill the player if touched, sending them back to a checkpoint or the start. These include spikes, electricity, water, falling platforms, lasers and more environmental dangers obstructing paths that must be carefully avoided.


On top of hazardous terrain and pits, players must watch out for robotic enemies patrolling rooms. These drones shoot bullets at the player character that must be jumped over, crawled under or dodged around without getting hit. Timing movements correctly is key to passing foes.


Clearing out the threats in a level allows the exit door to open, enabling the player head through to the next challenging floor. Players complete rooms trying not just to reach doors but to do so rapidly with few deaths, especially as time limits apply pressure later.


As players clear rooms, they advance vertically up through the towers’ floors. The path upwards continually adds new twists on obstacles to overcome. Across hundreds of floors, difficulty escalates demanding players sharpen their skills not just to proceed but to excel.
