There were numerous games you could play on Avago, by pressing the red button on the Sky remote. The main game was Avago Balls, a live bingo game. Other games included Spin 2 Win and Trackside. The official Avago website game's descriptions:
Avago also played Big Shuffle, a live card-turning game in which viewers bet on whether the next card turned would be higher or lower than the current one.
Avago Balls was the main game on the channel; it was a live show that broadcast on the channel for ten hours every day. It worked in a similar way to bingo with presenters pulling the balls and players buying electronic playing cards. The interactivity was emphasised with text messages being read while the balls were being pulled, a daily poll on a topical issue voted via the Sky remote again while playing and special prizes such as a weekly draw.
No actual skill (or activity) was required to "play" Avago Balls. Players bought "cards" via their Sky remote handsets, and watched as the system checked them automatically against the balls that had been drawn. Claiming a win was done automatically too.
One major innovation was that each player's cards were superimposed onto the broadcast picture by software running in their Sky set-top box (the box had to remain connected to Avago by phone during play; this link was used to download the cards' numbers and patterns). This gave a much stronger illusion of actually participating in game of skill rather than a lottery.
