Logical card puzzle game with the goal to find all the Triad sets with specific attributes combination.

Add cards one by one to the screen from 81 cards pack. Each card has four attributes:

- Shape (circle, square, triangle)
- Color (red, green, blue)
- Filling (full, half-empty, empty)
- Number (one, two, three)

Your task is to search for a set of three cards (Triad) that meet one of two simple rules for each attribute:

- Attribute is equal on all three cards
- Attribute is unique on each of three cards

Speed and precision is the key to the highest score as it is evaluated from the time reached and penalty points that you get for:

- Hints used (using a hint shows a Triad card by card or tells that there is no Triad on the screen)
- Wrong Triads (marking 3 cards that are not a Triad)
- Unnecessary cards (adding a card while there is a Triad already on the screen)
