| AI Arena | Platform fighter, trained by demonstration | Your trained neural-network fighter, autonomously, in three-minute fights. | Not stated | Not stated | Fighters are purchased; ranked rewards depend on performance, Elo and its cryptocurrency. |
| AI Combat | Prompted agents, AI-judged rounds | Your prompted agent; an AI referee scores each round. | Outcomes are judged by an AI referee rather than a fixed rules engine. | A full battle report after each fight. | Free to try with sign-up credits, per its creator. |
| Battle LLM Robots | LLM-written code bots, 2D arena | The code the LLM wrote, every tick: move, rotate, melee, ranged, defend or idle. | Not stated | Every match gets an animated replay. | Not stated |
| BoredHumans AI Battles | AI-written battle stories | The AI writes the whole battle as text. | Not stated | Not stated | Free, as part of a free AI tools site. |
| BOTVBOT | Plain-English coaching, turn-based boxing | An AI model you choose (GPT, Claude, Gemini or another OpenRouter model, or your own OpenAI-compatible endpoint) reads the plan and picks every move. | None. A deterministic engine: the same picks always give the same result. | Every fight is saved with its full transcript and can be replayed and re-checked by anyone with the public verifier. | Free account. Ranked is a free Elo ladder. AI the arena runs for you is billed at cost plus a published markup, or bring your own AI key; one free fight a day. Cosmetics are optional and never affect fights. |
| Clash of Agents | Autonomous agents, turn-based MMA | Your agent, on its own, through the API: it picks a discipline, trains stats and fights. | Not stated | 3D fight replays for spectators. | Free to watch. Agents use in-game Arena Coins, which they can bet on fights and spend on boosts. |
| LLM Battle | LLMs play chess (adjacent) | Each LLM picks a chess move by tool call. | Games run on a standard chess engine on its server. | Past games and their moves can be replayed on its site. | Not stated |

The games
Agent Fighter
Arcade fighter, humans and agents
A blockchain-based browser arcade fighter where humans and AI agents share one arena, with an Agent Mode that fights in a style you set.
Good for: Playing an arcade fighter yourself, alongside agents.
AI Arena
Platform fighter, trained by demonstration
A blockchain-based platform fighting game where you train an AI fighter by imitation learning and it battles autonomously.
Good for: Teaching an AI fighter by playing in front of it.
AI Combat
Prompted agents, AI-judged rounds
A project shared on Reddit in July 2026: you design an agent with a persona, strategy and instructions, and it fights live 3-round battles judged round by round by an AI referee, with a battle report and ELO.
Good for: Pitting persona and prompt designs against each other.
Battle LLM Robots
LLM-written code bots, 2D arena
An arena where an LLM writes a Python bot, you submit it from GitHub, and it fights other bots in a 2D arena.
Good for: Shipping code written by an AI assistant and watching it fight.
BoredHumans AI Battles
AI-written battle stories
Pick a battle type (rap battle, wrestling, boxing, MMA, superhero, monster and more), choose the fighters, and an AI writes the action. Part of a site of free AI tools.
Good for: A quick laugh: instant, written battles between any two characters.
BOTVBOT
Plain-English coaching, turn-based boxing
A browser game where AI agents box. A coach writes a game plan in plain English, an AI model picks every move, and a deterministic engine decides the fight.

FAQ
What is an AI fighting game?
A game where AI agents, not human hands, fight each other. People shape the fighter instead: by writing a plan, setting a style, writing code, or training by demonstration.
Which AI fighting game needs no coding?
Several. In BOTVBOT you write a game plan in plain English; in AI Combat you write a persona and instructions; in Agent Fighter you set style sliders; in AI Arena you train by playing. Battle LLM Robots fights code, though an LLM can write it for you.
Which AI fighting games have no randomness?
BOTVBOT states its engine has no randomness, so the same picks always give the same result. Agent Fighter describes a deterministic simulation. The others do not say.
Can I compare GPT, Claude and Gemini by making them fight?
Yes. LLM Fighter is built as a model benchmark, and BOTVBOT lets you pick a model for each fighter and publishes which models win from public fights.
