Is there an online, free Scrabble game?

1. http://scrabblegames.info/
For a non-nonsense, single-player Scrabble adventure online, http://scrabblegames.info/ could be a fine choice. However, this is an unofficial site with an unofficial board design, so it’s not exactly like the official Scrabble board, nor is it like Words With Friends. It is close enough, though, and you can play Scrabble against computer rivals across five levels of difficulty.
2. Funky Potato
If you would rather not use http://scrabblegames.info/ for any reason, Funky Potato offers the very same game version with matching functionality. It is the same modified Scrabble game board, though the site has a busier layout. In addition to the Scrabble game, Funky Potato offers a wide variety of other free online games as well.
3. Pogo Games
This has been around as an online gaming site for many years. You can play Scrabble against computer-controlled players for free here. However, you will need to deal with interstitial video ads that interrupt your play. While you do not need a Pogo account to play, signing into your account will save your game progress. You can upgrade to a paid Club Pogo account if you prefer an ad-free experience.
