Deal a hand from the spot and take a random seat. Each decision is graded against the simulation, with the solver's mix, the draw, and the EV you gave up.

Ram Usage
Three- and four-player openings can fit on a laptop. Full five- and six-player openings need substantially more memory. These are current solver estimates for a fresh 3rd-street situation with every player still in, solving through to showdown.

~0.9 GBestimated solver RAMFits smaller machines4 players
~3 GBestimated solver RAMLaptop-sized workload5 players
~31 GBestimated solver RAMNeeds a high-memory machine6 players
~337 GBestimated solver RAMWorkstation or server territory
Leave room for the rest of your computer. These figures include the solver’s working memory and runtime allowance, but not the operating system, desktop interface or other apps. A 32 GB machine has very little headroom for a 31 GB solve.
Starting on a later street or with fewer players still in can reduce the requirement substantially. The app estimates your exact situation before you run it. Saving only the opening street reduces the saved file size, not the RAM needed to solve the full hand.
How these estimates were calculated
Calculated from the current engine’s memory estimator for the full street-tree strategy, with uniform starting ranges, a four-bet cap, eight worker threads and the same working-buffer settings at each table size. Figures are rounded, use decimal GB, and are capacity estimates rather than measured peak usage. Cards, betting history and solver settings can change the result.

A–5 and 2–7 Razz solvers
Both Razz variants are included in each license. Pick the game when you create a situation: the hand rankings, board order and bring-in rule follow it, and each saved simulation stays tied to its game.
A-5 Razz solver ace to five
Standard Razz is seven-card stud lowball with ace-to-five hand rankings. Use the A-5 Razz solver to study starting hands, third-street openings and later-street betting against the ranges you enter.
A♠2♦3♣4♥5♠
- Aces are low. Straights and flushes don't count against you.
- The best hand is the wheel, A-2-3-4-5.
- Highest door card brings in, aces low; ties go to the highest suit.
2-7 Razz solver deuce to seven
Deuce-to-seven Razz uses the stud format with 2-7 lowball hand rankings. Use the 2-7 Razz solver to study how high aces, straights and flushes change your strategy. This is the Razz variant; 2-7 Single Draw and Triple Draw are separate games.
7♣5♦4♠3♥2♣
- Aces are high only. Straights and flushes count against you.
- The best hand is 7-5-4-3-2 of mixed suits.
- Highest door card brings in, ace high; ties go to the lowest suit.
Questions
Razz solver FAQ
What is a Razz poker solver?
A Razz poker solver studies betting decisions for specified cards, player ranges and stakes. RazzEdge simulates the remaining hand and reports action frequencies and expected value (EV), then lets you practise those decisions in its trainer. It supports both standard A-5 Razz and 2-7 Razz, from third street through seventh street and showdown.
How is a Razz solver different from an equity calculator?
A Razz equity calculator estimates a hand's share of the pot at showdown against other hands or ranges. A solver also models betting decisions. RazzEdge shows how often its strategy folds, calls, checks, bets or raises where those actions are available, along with EVs, so you can study how to play a situation.
How do I buy RazzEdge? Do I need an account?
RazzEdge Complete Solver costs $25,000 USD for two licenses. Each license includes A-5 and 2-7 Razz, and the purchase includes three example simulations for 3rd street. The $5,000 Edge Pack includes any 10 simulations of your choice for any street with 2 to 6 players, available in your web browser and on mobile. Email [email protected] to purchase. No account or registration is required.
Is it a GTO solver?
It runs a Monte Carlo (MCCFR) simulation of the whole remaining hand and shows action frequencies with EVs in big bets. Results are estimates with sampled intervals, not a proof of equilibrium. Run longer, and measure more hands, to tighten them.
Does it infer ranges from the earlier betting?
No. Each seat's range is what you enter: any holding by default, or a list of hands with weights. Up-cards and folded seats are counted automatically.
Which betting structure does it model?
Fixed-limit seven-card stud: ante, bring-in, completion, small and big bet, four-bet cap. Stakes are set per spot. All-ins, side pots and the paired-board double bet are not modelled.
Can I share a simulation?
Yes. Each saved simulation is a single file in a folder you choose. Copy it to someone else, or open theirs, and continue solving from where it stopped.
What hardware do I need?
For full third-street starts with everyone still in, the current estimates are about 0.9 GB of solver RAM for 3 players, 3 GB for 4, 31 GB for 5 and 337 GB for 6. Allow additional RAM for the operating system, desktop interface and other apps. Later streets and fewer active players can need much less. The app estimates each situation before it starts.
