Day & Night

Day or night? High or low? In each round of the card game Day & Night, players try to decide whether high or low numbers are more valuable based on the cards that everyone plays — and that can change instantly, possibly leaving you in the dark when it comes to scoring.

Each round plays out as follows: First, reveal the top card of the draw pile and place it next to the time card. Next, each player chooses one card from their hand, then reveal them simultaneously; if an odd number of revealed cards have a time symbol, flip over the time card. Then repeat this process, with each player choosing, then revealing another card from their hand, flipping over the time card again if an odd number of revealed cards have the time symbol.

Now determine who won the round: If the time card shows the sun, the color with the highest visible sum among visible cards (which includes the first card revealed) is the winning color; if the time card shows the moon, then the color with the lowest sum wins. All players who have played at least one card in the winning color now collect any visible card and place it in front of them. Remove all the remaining cards from play, deal two cards to each player, then start the next round.

When the deck has no cards in it, the game ends, and players tally their score based on the number of stars on cards in front of them. Whoever has the most stars wins.
