In episode 5 of Ro-Kyu-Bu!, Subaru is trying to build teamwork by playing cards with the team members.
The first shot shown is of cards sequentially placed on the floor. There are some hearts missing.
Then, each player goes around in the circle (they all have one card left except one). In this case, they each passed on their turn, until a fight broke out, and one player was holding two cards: the 5 and 8 of hearts, and was accused of "holding up" the game.
What is this game they're playing (and is it American, Japanese, or otherwise)? And, how was the player with the 5 and 8 of hearts holding it up?
