Poker Platform Software
Online Poker Software for Operators
Most poker software is sold to people buying developer hours. This is built for the operator who has to run the room: seat players, settle hands, take rake, prove fairness to a regulator and keep the tables full on a Tuesday night.
Certified RNG
Anti-collusion monitoring
Multi-table tournaments
White label or custom
What is online poker software, and what does an operator actually need?
Online poker software is the platform a poker room runs on. It combines the game server that deals and settles every hand, a lobby that seats players, a wallet that holds balances and takes rake, a tournament engine, and a back office for configuration and reporting.
The distinction that matters commercially is between a poker game and a poker room. A game deals cards. A room has to seat a player in under a second at peak, keep a cash table alive when it drops to three-handed, settle a side pot correctly when two players are all in for different amounts, take rake in a way your accountant and your regulator both accept, and produce the hand history when a player disputes a pot six weeks later.
That is why multiplayer poker software is bought rather than written. The certified random number generator, the anti-collusion tooling and the audit trail are the expensive parts, they are the parts a testing house examines, and they are already built here. Poker also rarely launches alone. Most operators run it beside a casino, which is why this platform shares a wallet and a back office with our turnkey online casino rather than sitting in a silo.
Game Variants
Which poker variants and formats are supported?
The platform ships Texas Hold'em, Omaha, Omaha Hi-Lo, Seven Card Stud, Five Card Draw and Razz. Every variant runs as a cash game, a Sit and Go or a scheduled multi-table tournament.
Omaha
Pot Limit and No Limit Omaha plus Omaha Hi-Lo with eight-or-better qualification. Four and five card variants, correct split-pot settlement.
Stud and Draw
Seven Card Stud, Stud Hi-Lo, Five Card Draw and Razz, with bring-in logic, exposed card handling and per-street betting caps.
Tournaments
Freezeout, re-entry, rebuy, bounty and progressive knockout. Late registration, synchronised breaks, hand-for-hand at the bubble and satellite qualification.
Architecture
How does multi-table, multi-player architecture hold up under load?
Gameplay is server authoritative. The client renders and sends intent; the server holds the deck, the clock and the pot, so a modified client cannot change a hand. Tables shard horizontally, which is what lets a tournament scale.
10k+
Concurrent seats
Tested at ten thousand concurrent seated players across mixed cash and tournament load, with headroom above peak rather than at it.
<80ms
Action round trip
Median time from a player acting to every seat at that table seeing it, measured in-region over websockets.
24
Tables per player
Multi-tabling regulars are your highest-volume rake contributors. The client is built so twenty-four simultaneous tables stay responsive.
100%
Hand replay coverage
Every hand is written to an append-only ledger before chips move, so any pot can be reconstructed exactly, including disconnects and all-in side pots.
Integrity
How is fair play guaranteed?
Through four independent controls: a certified random number generator, continuous collusion and bot detection, an append-only hand history, and jurisdiction-level responsible gaming enforcement. Each produces evidence a regulator can inspect.
Certified random number generator
The shuffle draws from a cryptographically seeded generator submitted for independent certification. Entropy sources, deal logs and per-hand seeds are retained as the evidence a testing house asks to see. Certification is issued against your deployment and jurisdiction, so it belongs in the launch plan rather than in a marketing claim.
Anti-collusion and bot detection
Hand histories are scored continuously, not audited quarterly. The system surfaces chip dumping between repeating pairs, persistent soft play between the same seats, timing signatures too regular to be human, and shared devices or networks seating at one table. Flags arrive in the back office with the supporting hands attached, so your fraud team reviews evidence rather than an alert.
Append-only hand history
Every hand is committed to an immutable ledger before chips move. Disputes are settled by replaying the hand rather than by reconciling balances after the fact, and the same record answers a regulator's request without a data extraction project.
Responsible gaming, enforced per market
Deposit and loss limits, session reminders, reality checks, cool-off and self-exclusion are enforced by the platform per jurisdiction, not left to the front end. Requirements differ by market, which is why they are configured alongside your gaming licence rather than after launch.
Commercial Routes
White label or custom: which route fits?
Take the white label route to reach market fastest on infrastructure and certifications we maintain. Take the custom route when you need to own the roadmap, run non-standard formats, or hold the deployment yourself.
White label poker software
Your brand and domain on a platform we run, update and keep certified.
- Live in roughly six to ten weeks
- Branding, lobby theming, currencies and payment mix
- Certifications and compliance maintained by OHS Gaming
- Shared liquidity options so tables fill from day one
- Predictable revenue share, no infrastructure to staff
Custom poker room software
The platform extended to your specification, deployed under your control.
- Own the roadmap and the release cycle
- Non-standard variants, formats and rake models
- Your infrastructure, your data residency
- Direct integration with an existing wallet or PAM
- Source access and handover available
Either route can start from an existing casino. If you already run one, poker becomes another vertical behind the same balance, and content from our casino game aggregator sits alongside the tables without a second wallet integration.
Mobile
Does it work on mobile?
Yes. The client is browser-based and responsive, so players join the same tables from phone, tablet and desktop with no download and no separate mobile build to maintain.
Mobile is where most poker volume now sits, and it is where badly ported clients lose players. The table view is laid out for a thumb rather than scaled down from desktop: bet sizing uses presets and a drag rail, action buttons sit inside reach, and pre-action checkboxes work without mis-taps. Session state follows the player across devices, so a player who opens a tournament on a laptop and leaves the house keeps their seat. Native iOS and Android wrappers are available where an operator wants app-store presence, but they wrap the same client rather than forking it.
Why OHS Gaming
Why operators choose OHS Gaming for poker
Because the hard parts are already built and already examined: certified dealing, collusion detection that produces evidence, and a hand ledger that survives a dispute. The rest is configuration.
Poker punishes shortcuts in a way slots do not. A slot that pays incorrectly is a bug. A pot that splits incorrectly is a dispute, a refund, a regulatory question and a player who tells a forum. We have built the settlement, audit and integrity layers to be the part you never have to think about, and left the levers you actually want to move, rake structures, blind schedules, tournament calendars and promotions, in the back office where your team can reach them without a release.
You also get people who have run rooms rather than only built them. That shows up in the unglamorous advice: how to schedule a tournament series that does not cannibalise your cash tables, when shared liquidity helps and when it dilutes your brand, and why the licensing conversation should start before the build rather than after it.
Questions
Online poker software FAQ
What is online poker software?
Online poker software is the platform an operator runs a poker room on. It combines the game server that deals and settles hands, a lobby and matchmaking layer, a wallet that holds balances and takes rake, a tournament engine for Sit and Go and multi-table events, and a back office for configuration and reporting. Buying it as a platform means the certified random number generator, the anti-collusion tooling and the audit trail arrive already built and already tested.
Which poker variants and formats does OHS Gaming support?
Texas Hold'em, Pot Limit and No Limit Omaha, Omaha Hi-Lo, Seven Card Stud, Five Card Draw and Razz. Every variant runs as a cash game, a Sit and Go or a scheduled multi-table tournament, with configurable blind structures, late registration, re-entry, bounty formats and satellite qualification.
Is the poker software RNG certified?
Yes. The dealing engine uses a cryptographically seeded random number generator submitted for independent certification, and the platform is built to present the evidence a testing house asks for: shuffle entropy sources, deal logs and a complete hand history that can be replayed hand by hand. Certification is issued against your specific deployment and jurisdiction, so it forms part of the launch plan.
How does the platform detect collusion and bot play?
Detection runs continuously against hand histories rather than as a periodic audit. The system scores chip dumping between repeating pairs of accounts, consistently soft play between the same seats, timing signatures that do not vary the way a human's do, and shared devices or networks seating together. Flagged sessions surface in the back office with the supporting hands attached.
Can the poker software be white labelled?
Yes. The white label route puts your brand, domain, lobby theming, currencies and payment mix on the platform while OHS Gaming operates the infrastructure and maintains the certifications. Operators who need to own the roadmap or run non-standard formats can take the custom route instead, where the platform is extended to their specification and the deployment belongs to them.
How long does it take to launch a poker room?
A white label deployment is typically live in six to ten weeks, covering branding, payment integration, responsible gaming configuration and certification against your target jurisdiction. Custom builds vary with scope. The dependency that most often sets the real date is licensing rather than engineering, which is why that conversation should start in parallel with the build.
