We are happy to introduce a brand new contest to you: the KNX Advent Calendar game!
**Win KNX devices and software tools**
From the 1st until the 24th of December you can win a KNX device or software tool each day. Just visit [the advent calendar game web page](http://www.knx.org/knx-en/advent-calendar/) and click on the door of the current day.
You will see a picture of a part of a KNX product and you have the chance to guess the product and the manufacturer. Take a right guess and you may win the shown device.
The next day you can revisit the page to see the solution/winner and play again by guessing the new shown product. But that’s not all!
Share the game’s web page and win an ETS5 Professional**
After you have taken a guess on the Advent Calendar game web page you will have the chance to share a message about the game on facebook and/or twitter. Each week during the game we will also give away one ETS5 Professional to someone who shared the message on the social media.
So go [visit the page](http://www.knx.org/knx-en/advent-calendar/) now and every day until the 24th of December to win fantastic prizes. Good luck!
