From 3ae90bcd3a345a932c6bc62cbb985a610caa78f2 Mon Sep 17 00:00:00 2001 From: Simon Tatham Date: Tue, 14 Nov 2023 12:41:46 +0000 Subject: Map: document explicitly that initial regions are immutable. Chris Boyle reports that a few users of the Android port were confused by this, e.g. https://github.com/chrisboyle/sgtpuzzles/issues/624 . (That seems surprising to me, since I view Map as extremely closely related to Solo - both are special cases of the general game class 'here is a partial k-colouring of a graph, find the unique total k-colouring that extends it', just with different ranges of k and different valid graphs. And surely nobody approaches a Sudoku puzzle and expects to be able to rub out provided clues they don't like! But I suppose if you're thinking of Map as a completely separate puzzle then perhaps that analogy doesn't have the same force.) --- puzzles.but | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/puzzles.but b/puzzles.but index 260ebbb..a48856a 100644 --- a/puzzles.but +++ b/puzzles.but @@ -1923,7 +1923,7 @@ You are given a map consisting of a number of regions.
