James H has implemented a new `Tricky' difficulty level in Light Up: 2005-09-01T11:57:56+00:00 Simon Tatham anakin@pobox.com 2005-09-01T11:57:56+00:00 94b36c11e00bb740813506b0d3911f90f1829941 a non-recursive level above Easy, which therefore moves the recursive Hard mode further up still. Play-testing suggests that in fact Tricky is often _harder_ than the old Hard mode, since the latter had limited depth of recursion and would therefore spot complex deductions only if it happened to start a recursion on the right square; Tricky may be limited in the sophistication of its complex deductions, but it never misses one, so its puzzles tend to be hard all over. Also in this checkin, a new source file `nullfe.c', containing all the annoying stub functions required to make command-line solvers link successfully. James wrote this for (the new) lightupsolver, and I've used it to simplify the other stand-alone solvers. [originally from svn r6254]
