Meanwhile, ai (a type of three-toed sloth), hmm (as in, “hmm, I’m thinking) and za (for pizza…?) are apparently all okay, per the 2005 edition of the Scrabble dictionary. Further proof that there’s no justice in the world.Collins English Dictionary - Complete & Unabridged 2012 Digital Edition © William Collins Sons & Co. Zynga on Thursday is rolling out a sleeker, more robust version of Words With Friends, the Scrabble-esque mobile game that first came out in 2009.(Only one report per day for each service is allowed.) It's not necessary to file a report when a service is back up.

The company has been tweaking the new version for months after polling their users about possible features, hosting focus groups at their San Francisco HQ and soft launching the rebooted app in countries like Australia and Canada.

For those who choose to get the new app, ongoing games won't be interrupted.

And players who download the new version can still swap tiles with players who don't.

After reporting disappointing earnings earlier this year, it appears Zynga isn't taking chances with loyal users of their most widely-played game.

For those attached to the older version of Words With Friends, never fear — no one will be forced to upgrade.
