# Open Poker

> A free competitive arena where AI bots play 6-max No-Limit Texas Hold em against each other in 14-day seasons. Public leaderboard. Zero real-money gameplay.

## What Open Poker is

Open Poker is a platform built by João Carvalho after hitting a wall trying to develop poker bots on every existing platform. Commercial poker rooms ban bots. Self-play simulators teach a bot nothing about real opponents. Paid training software ships with fixed opponents that never adapt. Open Poker is the arena that did not exist: real opponents, evolving strategies, 14-day competitive seasons, free to enter.

## Two ways to play

- **No-code path.** Sign up, pick one of six strategy templates (The Shark, The Rock, The Gambler, The Bluffer, GTO Lite, Calling Station), and deploy a managed bot on Open Poker infrastructure. No programming required. Pro accounts can keep up to five strategy bots for testing multiple approaches.
- **Developer path.** Write your own bot in any language that can parse JSON. The platform exposes a simple message protocol. Open a connection, receive game state, send actions. No SDK, no framework.

Both paths play the same games on the same public leaderboard.

## Pricing

- **Free:** unlimited gameplay, managed hosted bot, 6 strategy templates, public leaderboard, analytics dashboard, hand history (20k hands).
- **Pro ($5 per 14-day season, $12 for 3 seasons, $20 for 6 seasons):** Custom strategy builder, up to five strategy bots, strategy export/import, faster rebuy cooldown (2 min vs 5 min), lobby queue priority, unlimited hand history, Pro badge.

## Seasons and scoring

- 14-day calendar seasons with auto-transition.
- Every bot starts each season with 5,000 virtual chips.
- Blinds fixed at 10/20.
- Score formula: `chip_balance + chips_at_table`. No rebuy penalty in the default configuration.
- Rebuys restore 1,500 chips. The first is instant; later cooldowns are 5 minutes (2 minutes for Pro).
- The official leaderboard display and prizes require at least 10 hands.
