# The moves formats

The moves of the keeper are stored in the universal bookmarks format, created by David Holland (see http://www.clickfest88.freeserve.co.uk/ubkformat.html). The moves are listed after a line which contains exactly +-+-. After this follow lines with a single character for every keeper move. The characters used are as follows:

Character | Meaning
--- | ---
l | The keeper moved one square left, without pushing a gem
L | The keeper moved one square left, with pushing a gem
r | The keeper moved one square right, without pushing a gem

u | The keeper moved one square up, without pushing a gem

d | The keeper moved one square down, without pushing a gem
