About

Singularity Signal builds GTO Hold'em Trainer — a training and review tool for No-Limit Texas Hold'em built on game-theory-optimal equilibrium.

What it does

You play hands against the engine and every decision is scored against equilibrium play. Heads-up river pots are solved live with CFR+; every other spot uses a high-quality heuristic approximation. A manual review mode lets you replay a hand step by step, and online tables let you play real people.

How accurate it is

Measured against exact CFR+ solutions, the median EV loss is 0.37% of the pot on the river, 0.54% on the turn and roughly 0.9% on the flop. Those are measured numbers, not estimates.

No real money

There is no wagering, no purchase and no cash-out of any kind. Chips are valueless scoring units. The product is free and supported by advertising.
