WPC: Round 12 Individual - Innovations

[uvo]

Kirch + Heim: Please clarify if triangles can be in diagonally touching cells (even if the triangles are not touching each other).

Triangles cannot be in diagonally touching cells. Same (in other rounds) for stars, battleships etc.

Generally, if the instruction say "objects cannot touch each other", it always means "cells with objects cannot touch each other". See the glossary (page 6 bottom).
