This is the four in a row game I made. When the game is turned on it will display a scroll text, a colorful animation and the replay of the last round.

To start a new round, turn upside down the game to dump the discs. Now the sides have a different color that change slowly, when the first disc is dropped the colors of the sides in that moment are assigned to the two players. From this moment the sides lights up with the color of the player that takes turn.

If one of the two players drop a disc in a wrong column, it is possible to pop it out and drop it in the new position, the game recognize that and will light up the disc of the correct color.

When four discs are lined up the game will blink them along with the sides lighted with the winner color. The battery lasts more than 5 hours and can be recharged with a micro USB cable like a mobile phone. While taking the pictures in a photographic shop I noticed that the sensors do not detect the disc if exposed to extreme intense light, so just avoid using it with a strong light directed to it.
