  A k-stable c-coloured Candy Crush grid is a weak proper c-colouring of a
particular type of k-uniform hypergraph. In this paper we introduce a fully
polynomial randomised approximation scheme (FPRAS) which counts the number of
k-stable c-coloured Candy Crush grids of a given size (m, n) for certain values
of c and k. We implemented this algorithm on Matlab, and found that in a Candy
Crush grid with7 available colours there are approximately 4.3*10^61 3-stable
colourings. (Note that, typical Candy Crush games are played with 6 colours and
our FPRAS is not guaranteed to work in expected polynomial time with k= 3 and
c= 6.) We also discuss the applicability of this FPRAS to the problem of
counting the number of weak c-colourings of other, more general hypergraphs.
