Violence in the game is shown via cards interacting with one another. The player will select a card with a character and drag it to the card which they wish to attack. A small animation will be seen (usually a slash or an arrow piercing the card), accompanied by a spray of blood. Number damage is then shown. Cards that are defeated disappear completely.
Some of the cards in this game contain images that may be scary to younger players.
Other issues
This game offers players the opportunity to purchase in-game items in the form of diamonds (an in-game currency) which can be used to purchase card packs containing randomised items. Parents, carers or other responsible adults should check to see what is being offered before making any purchase on behalf of a child. It should be noted that the game can still be played without the need to purchase such items.
