Quadrum: words

This is a word puzzle with nice graphics.
This game does not have any goal for you to achieve, there is no time limit or any kind of "end of the game". You just play with words and letters, as long as you want, doing it as fast or as slow as you pleased. When quitting the game - everything is saved, so the next time you can continue exactly where you stopped.
Slide rows and columns to combine letters into words. Words must be at least 4 letters long, left to right or up to down.
Once you have a word - touch and hold any letter in the word to highlight it. If its found in Quadrums dictionary, it will glow.
Double-tap highlighted word to submit it - you will get score bonus (the longer the word - more score you get) and new letters will be generated.
Try building chains of words - words intersecting vertically/horizontally. The whole group will be submitted when you double-tap any word in the chain. Submitting chains gives you higher score.
You can have only one word per row or column.
