Wordtrix is a great concept marred by two major omissions. Firstly, and least importantly, there's no next block display so you cannot plan ahead. Secondly, and vitally, all letters have an equal chance of appearing. If this doesn't sound such a game-killer, consider this: I just played a game in which I got five X cubes and only a single letter E. The letter X is present in only a few English words, the letter E is the most common. Also, bear in mind that with very few exceptions most words need at least one vowel, and yet in this game there is only a 5 in 26 (just under 1 in 5) chance of one appearing. The game needs adjusting so that letter randomness is based on how commonly that letter appears in the language.
