From 12cb1adc886078d715abbc04e80912703340f496 Mon Sep 17 00:00:00 2001 From: Simon Tatham Date: Tue, 17 Apr 2018 18:30:48 +0100 Subject: Galaxies: clarify wording of completion condition. A user mailed me today having found it less than clear from the docs that Galaxies will only accept a solution if the set of filled-in grid edges consists of _exactly_ the ones that separate two distinct regions, rather than consisting of _at least_ those and perhaps others which neither break rotational symmetry or disconnect any region. --- html/galaxies.html | 10 +++++++--- 1 file changed, 7 insertions(+), 3 deletions(-) (limited to 'html') diff --git a/html/galaxies.html b/html/galaxies.html index 8041a95..32e4e1d 100644 --- a/html/galaxies.html +++ b/html/galaxies.html @@ -1,8 +1,12 @@ Galaxies
