How to Play Cosmicon, Roll On!
The gameplay mechanics blend card selection with dice-based combat. Before each match, you’ll choose one Character Card with unique abilities. Victory requires strategic thinking—each card excels against specific opponents, so studying their strengths matters.

During battles, players alternate turns rolling dice to attack and defend. When attacking, your opponent simultaneously defends by rolling their dice. If your selected dice values exceed theirs, you’ll deal HP damage. The goal? Reduce enemy HP to zero through clever dice combinations that trigger your card’s special abilities.
