ROUNDER.
The most dangerous amateur at the table didn't get there by accident.
A private cardroom where every opponent remembers every hand, every coach reads every spot, and every session makes you sharper.
The Problem
You play 2-3 times a week. The regulars play every day. They study GTO solvers, review hand histories, and talk strategy with each other. You show up, buy in, and hope for the best.
The tools that exist are built for grinders. The language is impenetrable. The interfaces look like spreadsheets. You don't need a GTO trainer. You need a cardroom that teaches you while you play.
Rounder is a private AI cardroom built for players who want to play like the pros — without becoming one.
Describe the players you actually face. Rounder builds them, seats them at your table, and coaches you through every hand in plain English.

Every AI villain's tendencies are grounded in how real players actually behave at real stakes — not theoretical models or random number generators.
What's Inside
Four surfaces. One cardroom. Everything you need to get sharper.
Spawn a Villain
Describe a player. Rounder builds them.
Write a few sentences about someone at your regular game — "tight older guy who only raises with premiums and always tells you when you make a bad call." Rounder generates a full AI opponent with a portrait, a backstory, and a complete statistical profile calibrated to match that playing style. Each villain has their own tendencies for VPIP, aggression, positional awareness, and tilt patterns. They remember how you play, and they adapt over time.
Coached Play
A coach that reads the table and tells you why.
Every hand, your AI coach watches the action, reads your opponents, and evaluates your decisions in real time. Before you act, it tells you what it would do and why — in plain English, not solver notation. After you act, it scores your decision and explains what you missed. Over time, your session scorecard reveals patterns: are you calling too wide on the river? Folding too much to 3-bets? The coach sees it before you do.
Workshop
Curated problems that sharpen specific skills.
Each workshop problem drops you into a frozen hand at a decision point — should you open AQo from under the gun? Is this a spot to squeeze? You make your choice, and the coach explains why one answer is better than the other, grounded in solver logic but explained in language you can actually use at the table. Problems are organized by concept and difficulty, with a recommended feed that targets your weakest areas first.
Poker Math
Speed drills that make the math automatic.
Six drill types — outs counting, equity estimation, pot odds, implied odds, bluff frequency, and should-I-call — each generated from a shuffled deck so no two are alike. They are timed and scored, designed to train the mental math you need at the table until it becomes instinct. You will stop reaching for a calculator. You will start seeing the numbers in real time. That is the edge.
Who This Is For
You're not trying to go pro. You're trying to stop being the mark.
Rounder is for the player who earns their living somewhere else — and wants to stop donating it at the table. Lawyers, founders, surgeons, engineers. People with 4 hours a week, not 40.
Your table is waiting.
