Preflo Dojo: Preflop Trainer

Learn the right preflop play — and the reason behind it.

■ A written explanation for all 7,700 questions
Every question explains why that hand is a fold, a call or a raise, so you
carry the reasoning over to hands you have never seen.
(Explanations are written in Japanese; the app interface is fully in English.)

■ Answers come from a GTO solver
Every scenario is based on the output of the same GTO solvers professional
players use — game-theory optimal decisions, not rules of thumb.

■ No ads, no account, works offline
Nothing interrupts a session, no sign-up is required, and every feature keeps
working with no connection. All data stays on your device.

■ GTO Drill (7,700+ scenarios)
Random situations test your Fold / Call / Raise decisions.
The other seats act out their decisions before the action reaches you.
Answer and you immediately get the correct play, the reasoning, and both your
range and your opponent's.
Advanced levels add frequency questions like "What % do you 3-bet A5s?"
20 questions per session — stop partway and your answers are still recorded.

■ Choose what you drill
Filter by table size, stack depth, position and hand type to grind the spots
you keep getting wrong.

■ 169-Hand Range Viewer
Interactive 13×13 hand matrix showing GTO ranges by position.
Color-coded Raise / Call / Fold for intuitive range visualization.
