I wanted to ask specific explanations about the game "Hive". In particular regard to two particular cases.
The first: If I move, with the spider or ant, for example, along the edge of the hive, and I get to a point where I can not access because the space was blocked by the arrangement of the pieces, but an intermediate movement allows me touching another piece, I can continue the movement?
Yes (if I understand what you're asking).
Second, it is said that a beetle beetles can climb other beetles; but must it be at a level immediately below, or can it take a leap of 2 "levels" or more?
You can change more than 1 level in a single climb.
PS: This last question is answered in Hive FAQ, by the way, which is recommended reading before posting rule questions. Enjoy!
