A Stone cannot have more than three cards on each side of the border; once placed, a card cannot be moved (p.6).

After playing a card and before drawing, you may claim Stones, but you can only claim a Stone once each player has played three cards on their side of the border, except if you can prove (using only already-played cards) that your opponent cannot beat your combination with any single remaining play (p.7).

Yes — after you play a card and before drawing, you can claim one or several Stones if you meet the claiming conditions (p.7).

Tied combination types are decided first by the highest total strength; if totals are still equal, the player who played his third card on the Stone first claims it (p.8).

No — when you take control of a Stone you place it beneath your cards and from then on no Clan cards may be played on that Stone, even if your combination was incomplete when claimed (p.8).

You may have as many Tactic cards in hand (within the seven-card hand limit), but you cannot play more than one card more than your opponent has played; if you are already one Tactic card ahead, you must wait until your opponent plays one (p.12).
