Logicon

Description from the publisher:

Logicon will teach you in an entertaining way how to think logically. You will discover that thanks to playing the game your reasoning is becoming quicker and better.

Behind each question mark there's always one of the eight colors hidden, though none of the colors is used more than once. Can you guess the colors and their exact positions? With the first click you grab a color and with the second you put it on a free space in the active row. As soon as you fill all five spaces, the row will close and the evaluation of your performance will follow.

If you don't manage to guess the right combination, you can have another go in the next round. The chart on the right side keeps you informed about your performance in the previous row. The game is over as soon as you guess all five hidden colors right. The sooner you manage to reveal them all, the higher score you get. If you achieve a record score, you'll have the chance to enter your name in the best players chart on the internet.
