Nine of Hearts (ハートの9, Hāto no Kyuu), also known as "Earth Invasion" (ちきゅうしんりゃく, Chikyū Shinryaku), is a game featured in Chapter 1 of Alice in Borderland RETRY.

Players have to survive all alien invasions.

Overview

Set-Up

• Location:
  Nations Theme Park
• Player Limit:
  Unknown
• Time Limit:
  10 minutes per round (6 rounds)
• Starting Items:
  A phone with six "LIFE" cards and one "DEATH" card

Rules

• Players need to protect themselves from the alien invasion by entering a shelter.
• Players are given phones that display six "LIFE" cards and one "DEATH" card (total seven), as well as six images of other participants excluding their own.
  • A "LIFE" card lets the player live. It can only be given to / received from another player. It allows the player to enter a shelter and survive. Only one "LIFE" card can be transferred by each player per round.
  • The "DEATH" card can nullify the player's "LIFE" card. It can be used at any point in the game.
• It is GAME CLEAR for the players who use up all of their cards before the end and survive all alien invasions.
• It is GAME OVER for a player if they do not receive a "LIFE" card and are not able to enter a shelter in time, as they will be attacked by aliens.

Details

"This is a game designed for those who wants their loved one to live and who will guarantee their survival. In the face of the alien invasion, please protect those you cherish."
— Game announcement

When there is a card exchange, the sender has to drag the card icon onto the face icon of the recipient. The recipient's phone shows what card it receives, but does not show who gives the card. Even though only one card can be given, multiple cards can be received by the same device. If an individual is defeated in the alien invasion, their avatar will no longer be able to receive any more cards. After obtaining the "LIFE" card, the players need to scan their phones by the pod entrance in order to get access. As observed by Arisu, the pods look small but they are not cramped inside. Each pod has a maximum capacity.

Violence towards other players and attempts to enter a pod without a valid "LIFE" card are punishable. After the countdown goes to zero, all the lamps at the ceiling, that look like small alien ships, start firing multiple lasers, destroying the hall and everyone in it.

The theme of each hall is based on different countries, and the landmarks of those countries are replicated in a miniature format. Some halls adjust the temperature in accordance with the settings (such as hot Egypt and cold Russia).

1. New York
2. European countries
3. Egypt
4. Russia
5. Cambodia
6. Japan

Solution

The disintegrated body shown at the start is a replica, and as such is meant to receive the "DEATH" cards from the players during the voting time, since the body does not die from an alien invasion. The capacity of a pod is increased in each round from one player to three players, therefore making a GAME CLEAR situation where all players pass is possible in this game.

The lines "This is a game designed for those who wants their loved one to live" foreshadow the possibility of this situation, as all the participants have an acquaintance they would like to survive with (Ryohei Arisu & Yuzuha Usagi, Himari Horikawa & Yuzuru Horikawa, Masatsugu Kitou & Nanase Onoue). The only exception for this is Naomichi Taiga, since he has no acquaintance paired with him, but has a desire to take down the others if the group plans to eliminate him.

Trivia

• This is the only game in the Alice in Borderland series to not reward a visa, and instead reward the freedom to return to the original world instantly, which may be due to the fact that this near-death experience is not as large-scale as the meteorite crash.
