Many reasons,
there is a big choice of games !
Sit'n'go (6 seater)
Double your money (6 seater) (from 30p up to 200 quid entry)
MTT's deep stack slow (5000c chips) 12-15 min levels
MTT's fast (1500 -3000 chips) 7-10 min levels
Cash games (not for me these but each to their own)
Plus they have live events around the country
Biggest plus for me is all UK players (some old Laddies players in chat box)
Community forum
(nothing changes there though, moans and groans 'bad-beats' but some funny stuff as well)
Ive played there for nearly a year now, with about 4 visits to Ladbrokes for a 7 card tourney..(the horse thing finished me there

)
So it suits me now to play on Skypoker. I think the main thing is to enjoy your poker and for me this is now home .. The TV makes it more interesting and enjoyable to watch and/or play ...!!
They are always listening to the players to improve the site and games, with interaction on the forum with presenters analyst and players..
My favourite games are the 'Double your Money' ( 6 seater ) you dont get lunatic's and you have to think about the tactic's to make the last 3 to double up )

Plus these games are around 15-30 mins which suits me fine !!
