Feed Gribble

A playtest. Three rounds, each with a different hidden taste. Roughly ten minutes.

How it works

Gribble has a secret rule about what makes a good plate. You draw a meal on the 8×8 grid; Gribble scores it 0–100 and tells you nothing else — no hints, no per-cell feedback.

Reach 95 and you've cracked it. You get twelve meals per round.

The kinds of rule Gribble can have are listed below and are fair game to consult at any time. Which one it picked is the puzzle. Please don't look at the page source — that spoils it, and spoils the data.

Tastes Gribble can have

Public by design. Today's is one of these — possibly two of them blended, with one mattering more.

  • count — about N lit cells, position irrelevant
  • symmetry — mirror, half-turn, or either diagonal
  • position — a half, the middle 4×4, or the outer ring
  • connectivity — one connected blob, no islands
  • shape — a solid rectangle or line, anywhere
  • neighbours — every lit cell touching exactly k others

Thank you — that's the playtest

One question worth answering in your reply, in your own words: how would you describe what you were doing?
