There appears to be divided opinion about DoN games. You need to be disciplined, understand some fundamentals of ICM and M and not get bored when theres little to no action. Personally, I like DoN games and have built a couple of decent rolls on the back of them. They dont suit everyone. I play a lot more cash games now, so the DoN games can seem boring by comparison.
Beware in DoN games, there is unspoken collusion come bubble time, between players who understand the dynamic of the game and those who dont.
Theres not a whole lot of decent strategy articles on DoN games. Its because the games are pretty simple to play. Start tight when blinds are small, loosen up and steal when blinds are large enough to warrant the play, then you should have enough chips to get past the all in or fold time around the bubble. About the only hand playable come bubble time is AA and even that has its detractors.
So before you jump in and find you are out of your depth, have a good look at what SnG's are about and find what suits your game, traditional SnG games, 90 man, 180 man, DoN games and everything inbetween.
