Level 3 has random starts so it can be useful for new players to re-start a few times to get a spot they like. Starting in smaller bonuses is better, since you can get your first bonus faster. After that just expand quickly - you want to catch the AIs while they're still squabbling with eachother. If you're too slow, one gets dominance and then is too big to take down. If you lose, surrender and look at history to figure out what went wrong.
Am I the first to experience a glitch where the shop runs amok, and very quickly flashes through everything, while the tutorial quickly auto clicks "next" and loops?
