Chess Miner v.1.1
Chess Miner is the first program in the Chess Puzzles Series.
It is intended to
improve one's concentration, memory, spatial imagination, and the skill to
discover regularities. It also helps consolidate one's knowledge about chess
pieces and their possible motions about the chessboard.
Only white pieces are involved in the game (officers, but no pawns!). The
computer makes moves with them. You are the miner, and only mines are at your
disposal. A move by the program consists in a single shift of a piece along a
certain route. Your move consists in the placing of a mine. Moves by both playing
sides alternate. Yours is always the first one.
Your aim is to "undermine" all white pieces by means of the mines. You have to
discover what route each piece follows and then place mines on each square of
A route is a certain sequence of squares along which a piece moves, obeying the
rules of the "big" game of chess as it does so. The length of a route, i.e. the
number of squares it consists of, varies from 1 to 5. The number of pieces also
ranges between 1 and 5; the length of their circuits may be different.
Unless undermined, a piece always travels along a route twice. Lap No. 1
"outlines" the circuit; lap No. 2 serves to prompt the human player to mark the
whole extent of the route by mines, starting on the square where the piece is
currently standing. A piece is regarded to have been undermined, and vanishes
from the board, if on each square of its current route it steps on a mine. As
soon as you have eliminated the last piece, you win. If you have failed to
undermine a piece in due time, the chessman changes the route. As soon as any
piece has reached the end of its third route for the second time, you lose.
The game has two modes: Play and Training. Play mode incorporates 10 levels of
difficulty. The difficulty of a given task depends on the number of pieces
involved and on the length of route of each piece. The more pieces are present
and the longer their routes, the harder is the user's task. All tasks are
generated by the program. The number of possible positions is practically
infinite, therefore the possibility of a position being encountered twice is in
the vicinity of zero. For each task you have coped with the program gives you a
certain number of points. The higher the difficulty level, the more points you
