This is what I wanted to do in clojure, have solver for a checker game. I started off with the below codes. (defstruct aount :h1 :h2 :h3 :h4) (def row1 (ref (struct aount "x" "x" "x" "x"))) (def row2 (ref (struct aount "x" "x" "x" "x"))) ;;Till row ten. In order to move a piece from one row to the other, I added. (defn extract-num [sand key] (let [n (Integer/parseInt (re-find #"\d+$" (name sand))) m (Integer/parseInt (re-find #"\d+$" (name key)))] (remake-row n m))) ;;I have not added the code to check if the intended space in occupied or not.And it can only move diagonally in the left side. (defn remake-row [i k] (if (and (with-in-range i bin)(with-in-range k ban)) ((eval(call-row i))(call-key k)) (defn call-key [m] (keyword (str "h"(inc m)))) (defn call-row [m] (symbol (str "row" (inc m)))) (defn with-in-range [m k] (and (>= (dec m) 0) (<= (inc m) k))) I A simple *move* involves sliding a piece one space diagonally forwards (also diagonally backwards in the case of kings) to an adjacent unoccupied dark square. A *jump* is a move from a square diagonally adjacent to one of the opponent's pieces to an empty square immediately and directly on the opposite side of the opponent's square, thus "jumping directly over" the square containing the opponent's piece. An uncrowned piece can only jump diagonally forwards, but a king can also jump diagonally backwards. For details check out this link http://en.wikipedia.org/wiki/Checkers.
