GamesGrid Backgammon

Online backgammon, how it was meant to be.

After eighteen years offline, GamesGrid is coming back. The server that ran from December 1996 to March 2008 — one of the first dedicated online backgammon platforms ever built, the home of the legendary bots GG Weasel, GG Raccoon, GG Forever, GGotter, GGbeaver, GGchipmunk and MrHyperBot — is being rebuilt from the ground up for a new generation of players. No coins. No paywalls in front of fair play. No rigged dice. A new platform, designed around competitive integrity and the deep mathematics of the game.

For the short, direct version of where the platform stands and where it's going, see backgammon online, done right → — the launch manifesto.

If you played here between 1996 and 2008, welcome back. If you didn't, this page is the short version of why so many people are still talking about a server that has been dark for nearly two decades.

What GamesGrid was

GamesGrid Backgammon went live in December 1996, in the very first wave of internet-hosted board-game services. It launched a few months after Andreas Schneider's First Internet Backgammon Server (FIBS) had proven that thousands of human players, scattered across continents, could converge in real time to play rated matches with proper Crawford and Jacoby cube mechanics. GamesGrid extended that idea into a polished, client-driven product with elegant board art, persistent ratings, structured tournaments, league play, and — critically — a stable of resident bots that became cultural figures in their own right.

The bots were the heart of the place. GG Weasel, GG Raccoon, GG Forever, GGbeaver, GGotter, GGchipmunk, and the tireless short-game specialist MrHyperBot were not generic computer opponents. Each had a distinct style, a known weakness, and a small mythology of famous matches. Beating GG Raccoon in a long money session was a rite of passage. Surviving MrHyperBot on a hypergammon ladder was a story you told for years.

The wider trajectory is well-documented. Backgammon was GamesGrid's first and best room. In April 2005 the company launched a poker product to ride the post-Moneymaker boom; the software could not compete with PartyPoker or PokerStars, and the strategic focus on poker meant backgammon — the room that had built the brand — was steadily neglected. In March 2008 the company was acquired by GamesAccount. The new owners ran the platform through 2008–2010 before the lights went out entirely. The domain came up for sale in 2020, was acquired in 2021, and we spent the years that followed restoring the original site from archive and designing what comes next.

The full thirty-year arc — both the game's and the server's — lives on the history page.

What GamesGrid is becoming

The 2026 platform is not a re-skin of the 2008 client. It is a new product built around one organising principle: competitive integrity, end to end.

Career Mode

A new single-player career mode is in development alongside the classic multiplayer rooms. The original GG Weasel, GG Raccoon, GG Forever, and the rest of the legacy bot cast return, joined by a new generation of named bot opponents spanning every level of competitive skill. Further detail will be published closer to launch.

Multiplayer

GamesGrid was always a human-versus-human server first, and the relaunch continues that. Money games, tournament play, leagues, head-to-head ladder matches, all under a single rating system that respects the conventions of the modern competitive scene: standard cube play with optional Crawford and Jacoby variants, beavers and raccoons in money sessions, automatic recording of every match for post-game analysis. Played positions can be exported to GNU Backgammon, eXtreme Gammon (XG), or BGBlitz for independent review.

Zero coin mechanics

We make this explicit because the broader online-backgammon industry has spent a decade obscuring it. GamesGrid does not run on virtual currency, lootbox progression, energy timers, or pay-to-win cosmetics that affect gameplay. The game decides who advances, not the wallet.

Mersenne Twister RNG

Every die roll on the platform is generated by the Mersenne Twister algorithm (MT19937), the same pseudo-random number generator used in GNU Backgammon, eXtreme Gammon's rollout engine, and a long list of scientific Monte Carlo simulators. Its period is $2^{19937} - 1$ — an astronomical figure that, in practical terms, means the sequence does not repeat across any human lifetime of play. It passes the standard statistical batteries (Diehard, TestU01 SmallCrush) and is the closest a deterministic algorithm gets to genuinely uniform randomness.

We say this in print because the alternative is the path some older servers took. SafeHarbor Games, for example, operated rooms that deliberately reduced the frequency of doubles to appease players who complained about "getting smashed by the dice." That is a fix to a perception problem that introduces a real-money cheating problem: in those rooms, any player who knew the doubles distribution was skewed had an exploitable edge over players who didn't. Our position is the opposite. Rolls are uniform, the seed is logged, the algorithm is named, and the audit trail is publicly inspectable.

The technical specifics — algorithm, seed source, audit policy — are documented on the Bots & AI page.

Why backgammon, in 2026

Backgammon is the oldest board game in continuous play. Boards consistent with the modern fifteen-checker setup appear in the Royal Game of Ur (Sumer, c. 2600 BCE) and the ludus duodecim scriptorum of imperial Rome. The medieval game tables descends from the same line; Hoyle standardised the English rules in 1743; the doubling cube was introduced in New York in the 1920s and turned a folk game into a piece of decision theory.

The game's mathematical depth is what attracts software engineers, quants, and Olympic-level competitors in roughly equal measure. The state space is small enough to be tractable and large enough to be deep: there are approximately $1.8 \times 10^{20}$ legal positions, a 21-element distribution over dice rolls, and the cube turns every position into a two-player no-limit equity decision. TD-Gammon, Gerald Tesauro's 1992 neural network at IBM Research, was the first program to demonstrate superhuman play through reinforcement learning — five years before DeepBlue beat Kasparov at chess, and twenty-four years before AlphaGo. Modern engines like GNU Backgammon, eXtreme Gammon, BGBlitz, and the open-source Wildbg continue that lineage and now serve as the calibration standard for every serious human player's PR.

We treat that depth seriously. Every page on this site — the opening-roll catalogue, the Rockwell-Kazaross Match Equity Table, the Neil's Numbers heuristics, the Crawford Rule deep-dive, the Golden Point and Prime Building strategy guides — is written as reference material, not marketing. Citations are footnoted, formulas are given in LaTeX, and the math is checked.

The global game

Backgammon is not a single game; it is a family of related games played under regional rule sets. The 2026 platform respects that.

Translations and locale-specific rules pages will follow the English encyclopedia. The glossary carries the cross-lingual term map; the rules pillar carries the regional variant definitions.

What you'll find on this site

This is the encyclopedia layer of GamesGrid. It exists alongside the playing client, not behind it, and it is written to stand on its own as the most factually dense backgammon reference on the internet.

The encyclopedia pillars:

• Setup — Step-by-step board setup, the starting positions for Tavla, Hypergammon, and Nackgammon.
• Rules — Board geometry, the fifteen-checker starting position, doubling cube mechanics, the Crawford Rule, the Jacoby Rule, regional Tavli variants.
• Mathematics — The Rockwell-Kazaross Match Equity Table, the Janowski cube-action formulas, Neil's Numbers mental heuristics, pip counts, race equities.
• Bots & AI — The technical lineage from TD-Gammon (1992) through Jellyfish, Snowie, GNU Backgammon, eXtreme Gammon, BGBlitz and Wildbg, plus Performance Rating methodology and the new GG bot roster.
• Strategy — All fifteen opening rolls with rollout data, the Golden Point, Prime Building, and second-roll reply theory.
• Glossary — Definitive technical definitions of every term in the modern game, structured as a DefinedTermSet for direct search-engine ingestion.

If you came here to play, the downloads page has the client. If you came here to understand the game, start with the rules and follow the cross-links — the encyclopedia is dense, interlinked, and meant to be read non-linearly.

A note on what we are not

We are not a casino skin. We are not a coin-grinding meta-game with backgammon stapled on. We are not running an opaque RNG service. The community rules — what counts as cheating, what counts as bad behaviour, and how disputes get resolved — are documented openly on the standards page. The membership and business-model details will be published closer to launch.

The pitch is simple. GamesGrid was a great backgammon server because the people running it cared about the game. The 2026 platform is being built on the same principle, with twenty more years of accumulated theory, twenty more years of accumulated AI research, and a server architecture that finally lets the original ambition breathe.

Welcome back. Or, if this is your first time — welcome.
