Spell Tower addiction 

Kim and I have gotten a little addicted to this word game lately. (Update: still addicted in late 2013. It’s got some persistence!) There are games modes for different mental modes — slow and meditative, or a hectic challenge — and the sound effects tickle my brain pleasingly. I’ve always liked word games, just like a writer, and I’ve played a million of ‘em, and this is one of the best. Mac or iOS only.
