No — players MUST NOT look at the fronts of the cards they were dealt; you hold them so others can see the fronts while you only see the backs (page 2).

You may give only one type of information on your turn: either a single color or a single value, and you must clearly point to the card(s) concerned (page 2).

Yes — information must be complete: if a player has, for example, two green cards you must point to BOTH green cards, not just one (page 2).

No — the informer must point to the actual card(s) being referenced, so saying someone has zero of something or pointing to nothing is not allowed (page 2).

If a played card cannot begin, add to, or complete a firework it is discarded and you remove the top black fuse token to the lid (and the third fuse placed ends the game as a loss) (page 2).

You regain a blue token by discarding a card (it returns a token to the table) or as a bonus when a firework is completed (playing a 5 returns a token if not already full); the game ends immediately on the third fuse (loss), immediately if all fireworks are completed (25 points), or after the final round when the deck is exhausted, and scoring is the sum of the highest card for each firework (page 2).
