About Card Duets

Card Duets is a cozy memory game where you match pairs of sea creatures — from octopus to shark. Flip two cards each turn, remember where they are, and clear every pair.

Four difficulty levels — from 6 to 14 pairs — suit both little kids and seasoned players. Four modes add variety: Classic with no limits, Time Attack, Survival and No Mistakes for a real challenge.

Journey mode is a map of island chapters, each with its own goals and stars. Unlock sea themes, card backs and UI palettes for pearls, come back for a daily reward, complete quests and achievements, level up and compete on the leaderboard.

Simple controls, soft visuals and a calm underwater mood — play solo or with the whole family!
