PDACorps has posted a review of Handmarks Scrabble, paying particular attention to the multiplayer element:
'After just doubling the density of pdas in my household, the idea of head-to-head gaming was simply too much to resist. Finally getting to use the IR port for a serious purpose (like fun) lead to a Google of 2-player pocket pc games of which, surprisingly, there are still few. Handmark leads the list, hands down.'
