Google's Project Fi presents a browser game and a free gift to subscribers
You don't have to be a Project Fi subscriber to enjoy the game (simply direct your mobile or desktop browser to fiholiday.withgoogle.com to play). Remember to tap your finger in front of the skier to change direction (or use mouse taps on your desktop device). And keep in mind, your character is moving downhill, not uphill.
While playing the game, Project Fi subscribers can sign in to receive a promo code for free in-flight Wi-Fi from Gogo to be employed on one flight only. The code must be used by March 31st, 2018.
