Level Devil is a 2023 troll platformer by solo developer Unept, where your only job is to reach the exit door — except the floor drops, spikes erupt, and ceilings slam down without warning.

You can play it free in your browser on Poki with no download, or as a mobile app on iOS and Android, with a paid version on Steam. Move with the arrow keys or WASD and jump with space or the up arrow.

It looks simple, but it's built to fool you, which is exactly why it went viral. Level Devil is a 2023 troll platformer created by solo developer Unept, where your only goal is to reach the exit door at the end of each short stage.

It looks like a plain pixel platformer, but floors collapse, spikes erupt, and ceilings drop without warning — a deception that has driven it past 35 million downloads. The trick is the game's whole personality.

Each level presents a tidy, harmless-looking room, then betrays the obvious route the moment you trust it. A platform vanishes under your feet, a spike shoots up exactly where you'd land, or a wall slides out to block a safe gap.

That bait-and-switch design made Level Devil a hit on TikTok and YouTube, where rage reactions and "gotcha" clips fueled its spread. The mobile version is even subtitled "NOT A Troll Game," which is the joke — it absolutely is one.

It carries an age rating around 9 to 10+, reflecting its cartoonish, non-graphic style. Key Insight: "The 'NOT A Troll Game' subtitle is the punchline.

Level Devil's entire design rewards distrust — every safe-looking platform is a setup waiting to spring." To play Level Devil, move your character to the exit door at the end of each single-screen stage.

The catch is that the level actively works against you — floors vanish, spikes shoot up, and walls slam shut. Success comes from cautious testing, memorizing where traps trigger through trial and error, and adjusting on each new attempt. There's no combat and no score to chase.

The entire loop is: enter a room, figure out which "obvious" path is a trap, die, and try again with that knowledge. Deaths are frequent but cheap — you respawn almost instantly, so the game encourages rapid experimentation rather than punishing you with long waits.
