Aro - Cards with a clue
The card game to stretch your brain. Follow the rules and see the pattern.
The goal of Aro is to find three cards that fit a actually simple scheme. Every card has four attributes: Amount, shape, color and pattern. Even if it looks easy at first, things can get pretty serious and let the player often doubt himself. In a race against the clock you have to find enough sets of three to advance to the next level.
