Frequently asked questions
What is a GTO strategy?
A game-theory-optimal strategy is a mathematically balanced way to play that cannot be exploited in the long run. Solvers compute these strategies for specific spots; GTOLens lets you browse the results.
Is GTOLens free?
Yes. Browsing the strategy library is free, with no account or download required.
Which games and formats are covered?
Pot-Limit Omaha preflop: cash-game spots at 50–150 big blinds and tournament spots at 30–50 big blinds, for 3-max, 4-max and 6-max tables.
Does it work on mobile? Is there an app?
The viewer is built mobile-first and runs in any modern browser — nothing to install. Telegram and Google Play versions are planned.
Where do the strategies come from?
Every spot is solved with professional solver software: the program plays the spot against itself over huge numbers of iterations until neither player can gain by deviating — that's the definition of GTO. GTOLens shows the solver's output exactly as computed, with no manual edits.
