Prepare for Christmas and try to TURN ON all the LIGHTS!


Lights on – how to play

Get ready for Christmas and try to turn on all the lights on the EnerTREE. But each time you click on a dark bauble to switch it on, any lighted baubles next to it will switch off – and vice versa. Try your luck and play now to illuminate the EnerTree. Have fun!


Hohoho -- you mastered all levels! Your glittering results made the holiday season even more beautiful.

Enter your name and see if you are one of the top players of the day. Then let yourself be inspired by our energy and fun facts about Christmas tree lighting.
