ATECCO is a deduction card game where you guess your rival's secret card from its traits.
Play with a friend on one device, against the CPU, or online.
■ Five ways to play
[Guess What] The main deduction game
Each player picks a secret card, then narrows down the rival's card with Yes/No trait questions like "Can it fly?" Outwit each other using Pass, Mirror, and Name questions.
・2 players on one device / vs CPU / Online
[Memory] A 6×6 memory duel
Match pairs to collect the most cards. Four skills — Peek, One More, Shuffle, and Steal — turn a memory game into a battle of wits.
・Solo time attack / 2 players / vs CPU
[Trait Karuta] A test of reflexes
Grab the card matching the called trait before your rival does. Two-player mode uses landscape view so both players share one board.
・Solo time attack / 2 players / vs CPU
[Card Combo] Hand-building strategy
Collect cards sharing a trait to build combos and score over three rounds. Rarer traits pay bigger multipliers.
・Solo score attack / vs CPU
[Perfect Match] A quiz of insight
Three traits are shown. Find the one card out of four that matches all of them, and chase your best score.
・Endless (3 difficulties) / 60-second time attack
