My question for those who are scoring 20K+ do you have a touch screen? My BB has a trackball to go back and forth from letter to letter. I don't see how I can score much higher than 12-15K without a touch screen.
Strategy-wise I often look for the word 'under' and then -tow, -mine, -stand, standing- taking - took - stood -study -score - scored
Basically I try to start with words that can be extended ex- should, shoulder, shouldering... things like that.
I have a high score of 18665 which I posted for 769th place. I use a trackball that sticks and i get some lag but only in the bonus round. I routinely get up to round 35-45. Common words I use are quest/ion/er/s/ing/ly, quarter/back/ed/ing, strength/en/ing, quaint/ly and thunder/ous/ly. I find it important to get tid of the 'j' / 'z' / 'q' whenever they come up with small words that connect, to clean up the board. This also gives you a better chance of getting good letters as vegetables, which is invaluable at level 25+. Try to use all the vegetables to spell a 10+ letter word for 200+ points. My best is 18 and 275 on the bonus round.
