From Wordament's blog post:
This morning we did a little more sanding on Wordament WP7. V2.2 should be available shortly and will reduce how often you see “Can’t connect to Xbox LIVE” or “Can’t connect to Wordament.net”. While there are still situations where those errors will legitimately display themselves, they are now even more resilient to network failures. If you have had connectivity issues with previous versions of Wordament this build should help.
We reviewed Wordament when it was first released on Xbox Live, and found a challenging and competitive anagram game:
[A single player Wordament]... would be a nice word game, where you score as many points as you can over a two minute period, pick up bonus points for finding a set of words (for example eight words connected to "birds" or "nine common words which include 'er'"), and try to beat your high score. Wordament takes an inventive and basic game, then adds some secret sauce to the recipe that has made it so popular.
The clue is in the name. Wordament is a portmanteau of 'Word Tournament'. When you start your two minute game with the sixteen squares... everyone in the world who is playing Wordament will have exactly the same grid and the same two minute time-frame to find more words, and score more points, than you.
