Weiß Schwarz (ヴァイスシュヴァルツ, Vaisu Shuvarutsu) is a Japanese collectible card game created by Bushiroad.

The game main attraction is the fact that its different expansions contain cards from different licensed properties (manga and anime series such as Bakemonogatari, Log Horizon, Madoka, Attack on Titan, The Melancholy of Haruhi Suzumiya and Fate Stay Night, among others).

[3][4] In 2010 Animate Times called the game "hugely popular", and noted that the game has produced 100 million cards within 21 months since its release, and 2000 million after 31 months.

[2] The game was also called popular by Anime News Network in 2013[4] and 2021,[5] and by GameRant in 2021.

[6] The game focuses on two main aspects: character battle and clock/level which regulate what cards can be played as well as acting as a player's life points.

Instead, the player shuffles the cards in their waiting room to put back in the deck area.

[7] When a player takes damage, the amount dealt is then added in cards to this area.

Cards in this area are placed faced down after trigger checks and cannot be revised or rearranged.

The phase where you play and move characters or event cards and activate start up abilities/effects.

The player declares an attack of choice with their characters one at a time to damage the opponent's life points (called "Clock" in Weiß Schwarz) and also their characters (if present) at the same time.

Characters that are put to [Reverse] will be sent to the Waiting Room during the Encore Phase unless otherwise stated.

If you declared a front attack, your opponent may play a character/event counter card, if they have one.

This phase occurs when the current player has decided to stop attacking.

Character cards form the base of the gameplay, serving as your means of damaging the opponent and subsequently defeating them.

Character cards have several features which include the level and cost on the top left, soul trigger on the top right, effects, color, power, soul output and traits on the bottom of the card.

Event cards have to meet color and level requirements to be played.
