JUCG Card Game Rules
The Jogmon Ultimate Card Game is a turn-based mini-game where players face off across five rounds. In each round, both players select a card that summons a Jogmon to battle. The player who wins the most rounds emerges victorious.
At the start of the match, one player is randomly chosen to take the first turn, with the winner of each round going first in the next. Each player begins with five cards drawn at random from their collection. At the beginning of every turn, both players select one card from their hand to play. The chosen Jogmon then battle automatically, with the outcome determined primarily by two key factors: Attribute Compatibility and Level.
Factors for Winning a Jogmon Battle
Attribute Compatibility
Each card has an Attribute, and certain Attributes have advantages over others. The more favorable the matchup, the higher your chance of winning the round.

Level
Cards range from Level 1 to Level 7, with higher levels typically offering stronger Jogmon. However, due to a known bug, Level 1 cards can occasionally defeat Level 7 cards, making every duel unpredictable.
Victory
JUCG is largely a game of probability. Even if you hold both the type advantage and a higher level, victory isn’t guaranteed — it simply increases your chances of winning.
Infinite Generation via Extra Card Summon
Certain combinations of cards can trigger special summons, creating entirely new and powerful cards during battle.
Known combinations include:
- Two cards of the same Attribute
- Two cards from the same Generation (from In-Training I to Champion)
Hidden combinations also exist, capable of generating rare cards not obtainable through normal play. Experimentation is encouraged to uncover these secrets.
Earning JUCG Cards Via Battle
After a JUCG battle, any cards your opponent used that you don’t already own are duplicated for you to choose as a reward. The more rounds you win, the more cards you can receive:
- 5 Wins: 3 cards
- 3–4 Wins: 2 cards
- 1–2 Wins: 1 card
- 0 Wins: No cards
Winning consistently is the key to efficiently expanding your collection. You can also battle the same opponent multiple times to earn more of their cards!
