No way to play against the computer

It would be good if there was an AI so that you could play this without having a friend nearby. This is the most-mentioned thing in the Android Market comments so it's definitely worth doing.

A simple AI might look like this, for the typical case where moves are restricted to a single mini grid:

switch (number of legal moves) {
case 1:
   take the only move
case 2:
case 3:
   examine who wins the minigrid, for all possible outcomes for this minigrid.
   pick the move that is most likely to lead to winning the minigrid (assuming all outcomes equally likely)
default:
   pick a move at random
}

I'm sure someone who knows something about AI could do much better.

I've added a framework for the AI, to make it easy for someone to write an AI if they want to. See https://github.com/MatrixFrog/scribedroid/wiki/WritingAScribeAI
