Indifferent.
I thought I'd try reviewing some of your flashes and see if it works. As usual, I'm sorry to say that there's a lot to be improved.
I assume it'd be fair to start by saying that there is no reason why you would play this when there's the board game. The board game is far more convenient, but this one forces two players to share a mouse. I wish that was the only problem though.
I'll start with the gameplay. This won't be easy because I'm barely familiar with Scrabble. For one, preventing players from starting without vowels isn't included in your game. If you are to literally make the cyber version of Scrabble without anything different, you might as well stick with the rules. Secondly, there is no scoring. You'd have to write the scores on paper, which is pointless as computer games like these are supposed to save you from bothering with a pencil and a paper. Third, the letters don't snatch to the grids. It's not a major problem, it just looks ugly and it's inconvenient.
Moving on to the design, the background is alright but the color of the text just doesn't match it. Especially the muting buttons are illegible due to the similar colors of the text and the background. Designing text with a different color in each letter is, by the way, as original as a cone of vanilla ice cream. Likewise, the text is really bland. If you have Flash 8 and up (I know you didn't make this in Photoshop), try assigning filters to the text. As long as you don't overdo it, it makes text looks much more attractive. The same thing applies to the game board, by the way.
The dictionary is well thought, I'll give you that. However, if you can somehow make it open in a tab WITHOUT skipping to that tab, you'd take an important step.
The music choice is OK, but it gets repetitive after a while. Furthermore, somehow, I think there are much more suitable songs for this out there. Maybe something more peaceful and calming.
In conclusion, I don't think there is any way that two people would enjoy playing this. Offline multiplayer flash games that can be played only with two people are rarely played, most people would prefer playing this alone for a few minutes before getting bored. Most importantly, there is no reason to play this when there is the REAL version.
Out of a score of 10, I took off:
-3 for the gameplay fallacies
-1 for the blandness
-1 for the music choice.
5/10 is the result, the vote result being 3/5. Frankly I feel like I've gone a bit easy on you, but it's probably because I can feel your potential. I won't be this kind next time. As I always warn you, don't jeopardize your flashes (or any kind of work for that matter) by rushing them. Keep working and improving. It'll take some time, but your hard work will pay off.
Best wishes.
