What’s included.
What ships today on Windows. Coming Soon items are listed separately and are not implied here.
Equity FN
Range-vs-range equity on the current board. Independent of a GTO solve — inspect equity without running Solve FN.
Solve FN
GTO for Flop, Turn, and River. One SOLVE control; street from board length (3 / 4 / 5 cards). Button reads Solving… then SOLVED.
Strategy grid
13×13 hand classes with mixed action frequencies at the current node. Legend colours match live Tree Settings bet sizes.
EV after a solve
Expected value from the solved strategy once the result is loaded — class averages and combo EV by action.
Equity tab & Reach
Equity on the same grid (also via Equity FN without solving). Reach toggle shows how much of each combo still reaches the node after the line.
Composition
How hero and villain ranges break down on this board (made hands, pairs, draws, air). Click a category to highlight matching hands.
Tree navigation
From the root node, walk betting lines and chance cards. Strategy and related views update for the node you select.
Save & review
Save a solved spot locally with SAVE. Open it later from Saved and walk Strategy, EV, Equity, Reach, and Composition in detail at any time — no need to re-solve to study the result.
Solve Quality
Quick, Normal, or Pro — how far CFR runs for the spot, not a second product.
Heads-up postflop
Hero versus one villain. Multiway trees are not in the shipping app.
Continuous Development
Your €68 lifetime license includes further solver speed upgrades when released. Further solver speed upgrades are under testing and validation (expected in the coming months). After that, the price will be adjusted — present buyers keep those upgrades included. Tournament Solver Mode and Exploitative Best-Response Solver are not included.
How to use P27.
Heads-up postflop: from board and ranges to a saved solve.
01
Set the spot
Heads-up postflop: hero versus one villain. Deal the flop, turn, or river to define the board.
02
Assign ranges
Edit the hand grid for hero and the villain. Preflop charts in the app can be applied or adjusted on the grid.
03
Choose Solve Quality
Pick Quick, Normal, or Pro before you solve.
04
SOLVE
Run Solve FN. Watch 0% setup, then iteration %, then 100% packaging until the badge completes and the button reads SOLVED.
05
Walk, save & review
Walk the tree. Read Strategy, EV, Equity, Reach, and Composition. Save the solved spot locally and reopen it later for detailed review without re-solving.

Suggested system specifications.
General guidelines based on typical use. Actual requirements may vary depending on range complexity, board texture, bet-size configurations, and other factors. These figures are provided for informational purposes only and do not constitute guaranteed minimum requirements.
Processor (CPU)
Modern multi-core processor (4 cores / 8 threads or above recommended). The solver uses multiple threads; more cores generally mean faster convergence.
Memory (RAM)
16 GB minimum. 32 GB or more is recommended, especially for Flop solves with wider ranges. Larger ranges or additional bet sizes increase memory usage. After a heavy solve, waiting a few minutes before the next one helps memory free up.
Storage
SSD recommended. The application itself is compact; saved situations benefit from fast storage so you can reopen and review solves later in detail.
Operating System
Windows 10 or later (64-bit) only. The native engine uses platform-specific optimizations including AVX2 where available.
Questions, answered.
No. It is a native Windows desktop application for studying GTO strategy. It is not a poker room and not a gambling service.
The current Windows solver: Equity FN, Solve FN (Flop / Turn / River), Strategy / EV / Equity / Reach, Composition, tree navigation, save situations, Solve Quality presets, and heads-up postflop. Buy by 1 December 2026 to lock €68 lifetime, including further solver speed upgrades when released. Tournament Solver Mode and Exploitative Best-Response Solver are not included.
Yes. Introductory lifetime price €68 until 1 December 2026. After that date the price will be adjusted for new buyers. Purchases on or before 1 December 2026 keep €68 lifetime, including further solver speed upgrades when released. We are not announcing the post-1 December 2026 price yet.
Equity FN calculates range-vs-range equity on a board independently — it does not produce a GTO strategy. Solve FN is the GTO solver for Flop, Turn, and River: it detects the street from board cards and computes strategy via the CFR engine.
No. The shipping app is heads-up postflop. Multiway trees, tournament / MTT / ICM as a working workflow, GTO Adjustments, Import, and villain profiles are Coming Soon. Tournament Solver Mode is also not part of the €68 licence.
Licences are sold through Lemon Squeezy (merchant of record). After purchase, the licence key arrives by email. Download the Windows installer from p27solver.com/download, install, then enter the key under Settings → License (or the first-run dialog). Two activations are included (desktop + laptop); deactivate a machine to move the licence.
No. P27 Solver is a downloadable native desktop app for Windows 10 or later (64-bit) only.
Preferably not. Solve FN is demanding on both CPU and RAM. Close or pause other taxing applications (browsers with many tabs, games, video editors, and similar) while a solve is running so the engine can use the machine fully. After a solve finishes, it is recommendable to wait up to about five minutes before starting the next solve so memory can free up — especially after heavy flop solves.
