Gonnect

A connection game blending Go mechanics with Hex-like objectives.

Gonnect

Gonnect is a strategy board game for two players invented by João Pedro Neto in 2000. It combines elements of Go and Hex, using standard Go equipment and rules, but with a connection-based winning condition: a player wins by forming a chain of stones that connects two opposite sides of the board. The game is notable for its use of the pie rule to balance the first-move advantage and for its no-pass rule, which forces players to eventually fill internal liberties, leading to a three-stage progression.

Lore & Background

Gonnect was discovered on July 18, 2000, by Dr. João Neto while he was updating his website 'Variations on Go'. He aimed to combine the play of Go with the connection objective of Hex but was stymied by deadlocks resulting from two-eye structures. In discussion with other game players, Neto realized that adding a 'no pass' rule would resolve this. Rules have been published proposing the use of both 13×13 and 9×9 boards, although 9×9 and smaller boards give the first player (Black) a strong advantage.

Reader's Guide

Gonnect occupies a unique niche between connection games like Hex and territory games like Go. While superficially similar to Hex and Havannah, advanced play transforms it into a game of territory, where building more territory than an opponent forces a connection and victory. The no-pass rule is critical: it prevents deadlock and forces players to eventually fill internal liberties, leading to a three-stage game: board-filling, eye-making, and eye-filling. The pie rule ensures fairness by allowing the second player to swap sides after the first move. Gonnect's significance lies in its elegant fusion of two classic game mechanics, creating a fresh strategic challenge that rewards both territorial and connection-based thinking.

Origins & Discovery

Gonnect came into existence on July 18, 2000, when Dr. João Pedro Neto was updating his personal website titled "Variations on Go." His original ambition was straightforward: merge the tactical richness of Go with the direct connection objective that defines Hex. However, he quickly hit a wall. The two-eye structures fundamental to Go created persistent deadlocks, rendering the hybrid unplayable in its initial form. The breakthrough arrived through conversation with fellow game enthusiasts. Together they identified that simply banning the pass move would dissolve these stalemates, forcing players to keep engaging until one side inevitably broke through. Neto published the rules for both 13×13 and 9×9 boards, though smaller sizes were noted to hand Black a significant first-move edge. The game was built entirely on standard Go equipment, requiring no new pieces or boards, which made it immediately accessible to the existing Go community.

Rules & Core Mechanics

At its core, Gonnect inherits virtually every rule from Go—liberties, captures, the suicide prohibition, and the ko restriction all carry over unchanged. The critical departure is the elimination of passing. A player who has no legal move simply loses, which fundamentally alters the endgame calculus. Victory is determined not by territory count but by building an unbroken chain of same-colored stones linking two opposite edges of the board, whether top-to-bottom or left-to-right. Connections follow only horizontal and vertical adjacency; diagonal neighbors do not count. The pie rule decides who plays Black. Because the board is square and both players can claim corners, skilled opponents frequently reach a "four corners" standoff where neither can force a connection. The no-pass rule then compels them to begin filling internal liberties, turning the contest into a subtle race of who runs out of safe moves first.

Strategic Evolution in Play

To a casual observer, Gonnect appears to belong squarely in the family of connection games alongside Hex and Havannah. Yet experienced players report a striking transformation: once the board fills and the initial racing phase concludes, the game mutates into something that feels remarkably like Go territory play. The typical match between evenly matched opponents unfolds in three recognizable phases. First comes the board-filling stage, where both sides race to establish a side-to-side connection before the position locks up. Next is the eye-making stage, during which players squeeze their opponent's remaining space to build safe groups with at least two eyes. Finally arrives the eye-filling stage, where each player must either fill their own eye space or dismantle the opponent's. The player who has accumulated the least territory generally finds themselves forced to make the last internal move and lose, making territorial efficiency a hidden but decisive factor throughout.

Place in the Game World

Gonnect occupies a distinctive niche in the landscape of two-player strategy games. It requires nothing beyond a standard Go set—typically a 13×13 or 15×15 board with black and white stones—making it instantly playable for anyone who already owns Go equipment. Its lineage is clear: the connection objective echoes Hex, while the capture and liberty mechanics are pure Go, and its two-player, no-pass structure sets it apart from both. The 9×9 variant was proposed in the published rules but is generally considered to favor Black too heavily, so the larger boards remain the preferred competitive format. The game first appeared publicly on Neto's "Variations on Go" website and has since been catalogued on community platforms like BoardGameGeek. Rognlie's early help page, archived in 2000, stands as one of the earliest written guides for newcomers. Despite its modest origins, Gonnect offers a compact yet deep alternative for players who find pure Go too open-ended or Hex too one-dimensional.

Frequently Asked Questions

What is Gonnect?

Gonnect is a two-player strategy board game created by João Pedro Neto in 2000. It merges the stone-placement rules of Go with a side-to-side connection objective borrowed from Hex.

How do you win at Gonnect?

A player wins the moment their stones form an unbroken chain linking two opposite edges of the board. There is no territory counting or capturing-based victory—connection is the sole goal.

What equipment do you need to play Gonnect?

The game uses standard Go stones and a Go board, so no special pieces are required. The only difference from a regular Go setup is the winning condition itself.

What board sizes does Gonnect support?

The game is designed for 9×9, 13×13, or 15×15 grids, letting players choose shorter or longer sessions.

What is the no-pass rule and why does it matter?

Because passing is forbidden, players must eventually occupy all internal liberties, which drives the game through a natural three-stage progression. This rule also works alongside the pie rule to neutralize the first-move advantage.
