About

Conway's Game of Life is one rule in one family of twelve. Browse them, draw into any of them, and wind any generation back. TWELVE FAMILIES Life — Conway, HighLife, Day & Night, Seeds, and the rest of the birth-and-survival space. Non-totalistic rules and other lattices — neighbour position matters; the grid can be square or hexagonal. Generations and Larger than Life — cells fade over time; bigger neighbourhoods make swimming blobs. All 256 Wolfram rules — one row of cells, time running down the screen. Turmites, reversible blocks, and WireWorld — Langton's ant, rules that run backwards, and a grid wired for logic. Excitable media, sandpiles, forest fires — spirals, avalanches, and spreading fire. Continuous fields — Lenia, SmoothLife, and Gray–Scott. WATCH IT, AND WIND IT BACK The slider seeks — drag it back and the earlier generation returns exactly. A frame at a time — step forward or back, or run from a crawl to a blur. Move around — pinch to zoom, drag to pan, tap to frame the pattern. WHAT IT CAN TELL YOU Measure — the rule, and the population, bounds, and activity on the canvas. Identify — a spaceship, its period, and how far it travels each cycle. A shelf of discoveries — the R-pentomino, acorn, diehard, the Gosper glider gun, and dozens more. MAKE THINGS AND KEEP THEM Draw in any model — a brush, patterns to load, and random soup. Build rules — birth and survival by hand, and the numbers behind every other model. Open what exists — RLE, MCell, macrocell, plaintext, Life 1.05 and 1.06, and rule tables. Save and export — a document you can reopen, or SVG, PNG, or RLE. Seven themes, and age colouring — newborn cells hot, still life cold, so motion shows without changing a cell. ONE PURCHASE, EVERY DEVICE One purchase covers Mac, iPhone, and iPad. No account, no subscription, no in-app purchases, no ads, no analytics, and no tracking. Every generation runs on your device; no cloud required.
