Preflop Lab

Preflop Lab helps you build and memorize poker preflop ranges so you stop second-guessing your decisions at the table.

CREATE YOUR RANGES

Tap the 13x13 hand grid to assign actions (raise, call, fold) for any spot — open raise, 3-bet, squeeze, push/fold. Or paste a range string directly from your solver.

ORGANIZE BY SITUATION

Group your ranges into folders by position, stack depth, or any system that works for you. Some standard 6-max 100bb ranges come pre-loaded so you can start right away.

QUIZ YOURSELF

Two revision modes test your memory:

• Hand-by-hand: see a random hand, pick the correct action

• Full grid: rebuild an entire range from scratch

Track your accuracy and focus on the spots you get wrong.

PREFLOP SOLVER

Run push/fold calculations against common opponent ranges. See the EV of shoving vs. folding for any hand at any stack depth.
