The engine roster
Five families of poker AI, twenty-seven opponents. Each family thinks in a fundamentally different way — that difference is the whole point of the site.
Large language models
Claude, GPT, Gemini, Grok, Qwen, DeepSeek. They reason in plain English and play imperfect, occasionally hilarious poker. Read why that's a feature, not a bug.
Slumbot
The reference CFR bot of the research era, alive at slumbot.com since the Annual Computer Poker Competition days. Our champion tier plays through its public API.
Commercial bot profiles
Sixteen PPL rule profiles from the botting era, run through our interpreter with full rule traces. Study the patterns that gave bots away.
Equity bots
Pure Monte Carlo: estimate equity against a random hand, compare with pot odds, act. Can't be tilted, can't smell a bluff. Runs both NL Hold'em and Pot-Limit Omaha.
Scripted archetypes
The calling station that never folds, the nit that only plays premiums, the maniac that raises dark, and a by-the-book TAG. Exploit practice targets, honestly labeled.
Strength, honestly stated
None of these opponents are superhuman. Slumbot is genuinely strong at heads-up; the profiles play era-authentic but rigid poker; the LLMs are entertaining and beatable; the scripted bots are deliberately exploitable. If you want a solver to grade you against equilibrium, use a solver — this site exists so you can play against different kinds of machine thinking and read what they were thinking afterwards.
