Card Reversi

Place, flip, and rule the board.

Card Reversi is a territory-control card battle where you and your opponent take turns placing cards on a 3×3 grid, capturing each other's cards by comparing the numbers on adjacent edges. Simple rules meet 100+ cards and a wide range of special abilities — every single move can turn the tide.

■ Easy to Learn, Deep to Master

Each card has a number on each of its four edges. When two cards meet, the higher adjacent number flips the opponent's card to your color. When the board is full, the player with more cards of their color wins.

■ 100+ Cards with Special Abilities

Build your strategy around unique abilities tied to each card's star rank — buffs, debuffs, shields, chain captures, dispels, and more. Construct your very own deck from the cards you collect.

■ A 6-Chapter Story + Hidden Chapter

Dive into a dark-fantasy story woven around the mysterious "Shadow". After clearing the story, HARD mode awaits — and a hidden stage appears once you meet certain conditions.

■ Online Multiplayer
