Conway's Game of Life

⚠️ Experimental — generated with no human supervision. This realm was produced automatically by an MCP-driven agent to exercise the gno MCP server and tooling, and to generate test content for gno compilers, linters and formatters. Not audited. Not for production. Full context & folder README: r/moul/x/daily

A port of Conway's classic cellular automaton to gno.land. The full board lives on-chain — every generation tick is a real transaction, shared state for whoever is watching.

Realm path: gno.land/r/g12cs4cehujpffpjpywmkqj43m6u5ya53nj69sjz/life

How it works

The board starts as a 20×15 grid seeded with a glider. Anyone can call Step() to tick the simulation, load a classic pattern, or sculpt cells by hand. All state persists between blocks.

Overview

Conway's Game of Life on Gno — the entire board lives on-chain. Anyone can call Step() to tick the simulation forward, load classic patterns, or sculpt cells one by one.
