I find it easier to rack up higher scores in Action mode, surprisingly. The burning tiles acting in real time, independent of word submissions, means you can better coordinate getting rid of them on your terms. Very fun arcade puzzler, very fucked up that the way EA wants you playing it nowadays is a nightmarishly-animated remaster on a costly subscription-based website. Track down a cheap physical copy if you can--shockingly, the DS version may be the most content complete in its gameplay.
