## What is Viper GTO?

Study the hand. Understand the decision.

Viper GTO is a Texas Hold’em study and practice app. Explore strategy away from the table, review hands you have played and build a more consistent study routine.

PRACTICE POKER DECISIONS
Choose an available training scenario, make your decision and compare it with the solver’s strategy and expected value (EV). Review your results and revisit decisions that need more practice.

EXPLORE STRATEGY
Browse available preflop ranges and solved situations. Inspect action frequencies and follow a line to understand how the strategy changes as a hand develops.

SOLVE CUSTOM SPOTS
Set the board, pot, stacks and player ranges for supported turn and river situations. Run the solver on your device and inspect its strategy. Results depend on the inputs and available device resources.

REPLAY AND REVIEW HANDS
Open saved or imported hand histories in a poker-table view. Move through the action street by street, revisit key moments and run analysis for supported hands when you choose.

TRACK YOUR SESSIONS
Record cash-game and tournament sessions with buy-ins, cash-outs and playing time. Keep your study and session history in one place.

ACCOUNT AND AVAILABILITY
Sign-in is required. Online library, training and saved-hand features require an internet connection. Available scenarios and usage limits depend on your account and are shown in the app. This version does not offer in-app purchases or subscription checkout.

FOR STUDY AND PRACTICE
Viper GTO does not accept bets, offer cash prizes or connect you to real-money games. Training uses simulated poker hands. Use it for practice and post-session analysis, not assistance during live play. No strategy tool guarantees results.

Available in English, Chinese and Spanish.
