What is the best free preflop trainer?

For drilling full opening ranges, Preflop Trainer (browser, no signup, no paid plan listed) and Lucid Poker (unlimited free preflop solves) are the most generous free options we checked.

Do I need range charts or a trainer?

Both: a chart shows what to play, a trainer checks that you remember it under pressure. Several tools here offer both.

Is Poker Puzzle Trainer good for preflop?

Not for learning full ranges: it has no range charts. It is useful to test preflop decisions in context, with an explanation for each spot.

Are these tools sponsored here?

No. We make Poker Puzzle Trainer, which we say openly; no other tool paid to be listed, and every limit comes from a source we cite.

Best Preflop Trainers 2026: Which Free Tool Teaches Your Ranges

By the Poker Puzzle Trainer team · Published October 21, 2026

The best preflop trainers in 2026 are the ones that both show you the ranges and drill them. For free range drills, Preflop Trainer (browser, no signup) and Lucid Poker (unlimited free preflop solves) are the most generous we checked; GTO Gecko, GTO Wizard and FreeBetRange add charts and trainers with daily caps. Poker Puzzle Trainer, which we make, has no range charts: it tests preflop decisions in context instead. Every tier below was checked on October 10, 2026.

Disclosure: Poker Puzzle Trainer is our own app. We compare it on the same criteria as the others and say where it falls short: no range charts, no range drill, and its preflop spots are a fixed selection, not a full range at every position and stack depth.

Try a preflop decision first

Under the gun with 9♠9♣ and 100 big blinds, you open to 2.5 big blinds; everyone folds to the big blind, who 3‑bets to 11. Fold, call, 4‑bet to 24, or jam?

How to choose

To learn your ranges: pick a tool with charts and a range drill, such as Preflop Trainer or Lucid Poker.
To build your own ranges: FreeBetRange is a range editor first, with a capped free trainer.
To test decisions in context (3‑bets, 4‑bets, defending, with a reason for each answer): that is what our trainer does, without charts.

The limit of preflop drills

Memorizing a chart is not the same as playing it: drills reward the right answer in a clean spot, while real hands add reads, stack sizes and history. Use a range trainer to learn the baseline, then decision spots to check that you apply it.
