I know, maybe it's the most stupid question anyone asked about this game, but I can't seem to find an answer in the rulebook:
1. lay out Nile cards
At the beginning of each round, the players draw 10 Nile cards from the supply and place them face-up on the 10 card spaces on the game board next to the Nile, beginning at the source.
1. What happens to the cards that are left on the board after phase 1?
2. Are they discarded from the game or do they stay put and new cards in subsequent turns are only drawn to cover empty spaces?
3. If the leftover cards are discarded, when will this happen? After phase 1 or at the end of the turn? Or after turn 2, 4 and 5 respectively?
