Bug ID: 407969
Summary: Hint system should not suggest unwinnable states
Product: kpat
Version: 3.6
Platform: Debian unstable
OS: Linux
Status: REPORTED
Severity: minor
Priority: NOR
Component: solver
Assignee: co...@kde.org
Reporter: et...@tague.me
CC: kde-games-b...@kde.org
Target Milestone: ---
SUMMARY
The hint system, at least in the case of Klondike, will suggest moves that will
put the game into an unwinnable state.
STEPS TO REPRODUCE
1. Begin a game of Klondike
2. Play to the point where a move could be made that makes the game unwinnable
according to the solver, and where the hint system suggests a poor move
3. Press 'hint'
4. Follow the movement the hint suggests
OBSERVED RESULT
Following suggested movement causes the solver to immediately report that the
game is no longer solvable.
EXPECTED RESULT
Hint system should verify that the hint given does not put the game into an
unwinnable state, and if so, provide an alternative hint.
