# Hex-grid strategy games: why six directions change everything.

> Square grids need special rules to fix their geometry. Hex grids don't. Here's the lineage — and the newest branch.

Why hexagonal boards keep winning in abstract strategy: no diagonal ambiguity, richer connection, natural encirclement. The games that prove it — Hex, Havannah, Hive, Tumbleweed — and where hexodic pushes next.

## Why do strategy games use hexagonal grids?

Because hexes fix the square grid's oldest bug: **diagonals**. On a square board, two diagonal neighbors touch at a corner — are they adjacent or not? Every square-grid game has to legislate an answer, and either answer distorts distance. On a hex grid every one of a cell's **six neighbors is equally adjacent**, so distance is honest, connection is unambiguous, and encirclement is a natural tactic instead of a rules patch. That's why the purest connection and territory games in the genre keep choosing hexes.

## The lineage, briefly

- **Hex** — the mid-century classic of the family: connect your two sides of a rhombus of hexagons before your opponent connects theirs. One rule, bottomless depth, and a mathematical guarantee that someone must win — no draws. The proof-of-concept that hexagonal adjacency alone can carry a game.
- **Havannah** — Christian Freeling's connection masterpiece on a hexagonal board: win with a ring, a bridge, or a fork — three different connection shapes, so threats overlap and defense is always triage.
- **Hive** — hexagonal adjacency without a board at all: the pieces are the terrain. Depth from piece asymmetry rather than geometry. [Our head-to-head with hexodic](/hexodic-vs-hive).
- **Tumbleweed** — a modern favorite of the abstract community: stacks project line-of-sight influence across a hex board, and territory follows reinforcement. A reminder the space is still being explored.
- **hexodic** — the newest branch: a radius-3 board of 37 hexes where the *cells themselves have height*. One stone type, terrain you terraform every turn, encirclement capture, and three simultaneous win conditions. [The full rules](/how-it-works).

## What hexodic adds to the family

The hex-grid classics each own one idea: Hex owns connection, Havannah owns multi-shape threats, Hive owns boardlessness. hexodic's idea is **elevation**: every cell carries a tier (0, 1, 2), your turn includes reshaping one cell, and a stone is exactly as strong as the ground under it. Combined with three simultaneous win conditions — connection (Network), capture (Takeover), and mobility (Strangle) — the six-direction geometry stops being just adjacency and becomes *terrain*.

The numbers behind that claim are measured, not vibes: branching factor **911 / 1,009 / 665** at half-moves 5 / 10 / 20, a **0.25%** draw rate, and **5.92-minute** mean sessions — chess-class depth compressed into a coffee break. Where it sits among the classics beyond geometry is on the [comparison page](/games-like-hexodic), and the genre-wide view is on the [abstract strategy hub](/abstract-strategy-game).
