Players are able to create their own unique characters in the same style and fashion originally present in Kingdom Hearts Mobile and Kingdom Hearts Re:coded's Avatar Menu. Battles consist of a strategic card-battling mechanic with a large emphasis on collecting cards and items. Cards can also be synthesized to level and evolve stronger cards and materials can be synthesized to strengthen the Keyblade's abilities. All controls, including moving around the field and battling, use the mouse. While the game can be experienced in single-player, cooperative multi-player is an emphasized element as cooperative gameplay is required to defeat raid bosses, which appear several times throughout the day. Additionally, players go into five Unions in which players defeat enemies together to collect light known as "Lux". At the end of each week, the total amount of Lux for each team is calculated and the team that gathered the most, take part in a mission where players can obtain special rewards.
The cards can be categorized by rarity, which spans from normal (N/N+) over rare (R/R+) to super rare (SR/SR+), by card type, or by alignment. The cards are divided into Attack cards (アタックカード Atakku kādo ) and Assist cards (アシストカード Ashisuto kādo ). Attack cards determine the player's attack and defense values while the assist cards are responsible for the maximum number of health points and Lux gain rate. There are three types of attack cards: Power (パワー Pawā ), Speed (スピード Supīdo ) and Magic (マジック Majikku ), each with a different set of techniques and preferred by certain Keyblades, increasing their attack values momentarily. Additionally, cards can be imbued with certain skills to expand their abilities or increase their stats, newly released cards will be boosted for a set period of time.
The alignment is mostly a cosmetic value that doesn't make much difference in the main portion of the gameplay, while it can trigger an additional damage boost called EX Card Bonus (EXカードボーナス EX kādo bōnasu ) during raids when using the correct Keyblade with the corresponding cards. The standard cards that the game was released with are called Upright cards (アップライトカード Appuraito kādo ) and only depict the heroes and supporting characters with a bright yellow and gold color scheme while the Reverse cards (リバースカード Ribāsu kādo ) only show the villains and enemies in a dark blue and purple color scheme.
