Kaijudo formats are different modes in which the Kaijudo Trading Card Game can be played.
Each format provides rules for deck construction and gameplay.
The tournament formats fall into two categories:
- Constructed formats. in which players may build their deck from all the available cards in the format and construct their deck prior to playing in the tournament.
- Sealed formats, which involve a restricted and unknown pool of cards, created by opening booster packs. These formats require players to build their decks as part of the tournament, with time allotted for deck building.
