Each cell may store a value.
PHP Code:
new c[ 3 ] = { 'a', 'b', 'c' }; // three
new a[ 2 ] = { 'a', 'x' }; // two
new d[ 4 ] = { 1, 2, 3, 4 }; // four
/*
So, d[ 0 ] = 1, d[ 1 ] = 2, d[ 2 ] = 3, d[ 3 ] = 4.
c = "abc";
c[ 0 ] = 'a', c[ 1 ] = 'b', c[ 2 ] = 'c';

You have to define 32 cells for all players. From 0 to 31 inclusive.
If you want to use the cells from 1 to 32 inclusive, you have to define 33 cells.
