off a vertex?)

Re Candy Crush, I read the rules to say that the solution can't contain three or more equal letters in a straight line, horizontal or vertical. On the other hand, elimination happens for any group of edge-connected equal letters of size at least three, e.g., for an L-trimino. Is that correct?
Second, why can't the top two rows of the example solution be ADBDBB,AADXDC? Is it because swapping e.g. R1C1 and R1C2 doesn't for a "new" group?
Not an L- Trimino. The rule says "horizontally or vertically consecutive cells" which means three letters in a line along a row, or a column. This may answer the second part too? |

3,4: No. For a shard all its fragments are edge-connected.
21,22: No. Vines travel via edges only. Its not explicitly mentioned though. We will make a note of this during Q&A. |

The rules state same digits cannot be placed in cells touching diagonally.Can same digits be placed in a single cell ? For instance, can the 2 sum be 1,1 if it doesn't violate the no touch rule with other cells?This case doesn't occur in the example . |

No. We will clarify this at Q&A too. |

Having R6C2 as sea and R7C1 + R7C3 as land and everything else as in example solution - would that be viable solution? If not, please explain why. |

It wouldn't because then there is no case within a and b where the given Sea cell in R4C4 has to be a Sea cell. |
