Preflo Dojo: GTO Poker Drill

Preflop is where every hand begins. GTO solver-proven answers for all 7,700 questions, each with a written WHY. Build real understanding, not just memorization.

Every poker hand starts with a preflop decision.

Preflop is the very first decision point of every hand. Your choice here fundamentally shapes the expected value of every street that follows. Yet most players still rely on gut feeling.

Preflo Dojo turns that guesswork into confidence — a GTO trainer focused entirely on preflop play.

■ Why You Can Trust These Answers Every scenario is based on GTO solver output — the same mathematical tools used by professional poker players. Not instinct, not rules of thumb: game-theory optimal decisions backed by math. Every question explains WHY that play is correct. (Explanations are currently in Japanese; the app UI is fully in English.)
