In Riftbound, if a player conquers both battlefields during their opponent's turn and reaches 9 points, do they win immediately, or must they control both battlefields simultaneously at the end of the turn?

Ruling: You win immediately upon reaching 9 points by conquering both battlefields, even if you don't control them simultaneously. You only need to successfully score at both battlefields, not hold them at the same time.

Sequence:

• Opponent gains 7th point for holding at start of their turn
• Opponent moves to your battlefield, you respond by moving away and conquering their battlefield (8 points)
• Opponent conquers the battlefield you left (opponent reaches 8 points)
• Opponent readies and moves back to where your unit is, you respond by moving away again
• This second move allows you to conquer the second battlefield during opponent's turn, reaching 9 points and winning

Nuances:

• You cannot score again from a battlefield you already held during that turn, even if you temporarily lose control of it
• Conquering can occur on your opponent's turn if your unit moves onto a battlefield it wasn't on at the start of that turn
• The winning condition only requires scoring at both battlefields, not simultaneous control
