An X user has gone viral after showing off a fully playable Pokemon-style RPG that was generated by the free version of Claude in under two hours using a simple one-line prompt.
The clip was shared by X user chatgpt21, who posted a recording of himself playing the game directly in a browser. The footage shows a classic top-down Pokemon-style experience, complete with tile-based maps, NPC dialogue, random encounters in tall grass, turn-based battles, and functional shops.
According to the post, the project was created using Claude 4.6 Opus, a model developed by Anthropic. The user said they prompted the model with a simple request: “make a pokemon clone as close as you can to the real game.”
AI creates Pokemon clone with one line prompt
“I told Claude 4.6 Opus to make a pokemon clone – max effort,” they wrote. “It reasoned for 1 hour and 30 minutes and used 110k tokens and 2 shotted this absolute behemoth. This is one of the coolest things I’ve ever made with AI.”
In a follow-up explanation, the user said the model independently chose to recreate a Game Boy-era Pokemon experience, rather than a modern 3D version.
“I just asked it to clone a pokemon game, and it went for the gameboy one on its own volition,” they explained. “Probably because it’s the easiest to replicate in html.”
The demo itself closely mirrors early entries in the Pokemon series, albeit with a much simpler art style. The player character walks between towns, enters buildings, talks to NPCs, and triggers wild encounters in tall grass.
In one battle shown in the clip, the player sends out a ‘Charmander’ to defeat a ‘Ratata’ before continuing through the overworld. The game also features a working Pokemart, where items can be purchased, further emphasizing the scope of the project.
