+Feature: code-breaker submits guess
+
+  The code-breaker submits a guess of four colored
+  pegs. The game marks the guess with black and
+  white "marker" pegs.
+
+  For each peg in the guess that matches the color
+  and position of a peg in the secret code, the
+  mark includes one black peg. For each additional
+  peg in the guess that matches the color but not
+  the position of a peg in the secret code, a
+  white peg is added to the mark.
+
+  Scenario Outline: submit guess
+    Given the secret code is <code>
+    When I guess <guess>
+    Then the mark should be <mark>
+
+  Scenarios: all colors correct
+    | code    | guess   | mark |
+    | r g y c | r g y c | bbbb |
+    | r g y c | r g c y | bbww |
+    | r g y c | y r g c | bwww |
+    | r g y c | c r g y | wwww |
+
+  Scenarios: 3 colors correct
+    | code    | guess   | mark |
+    | r g y c | w g y c | bbb  |
+    | r g y c | w r y c | bbw  |
+    | r g y c | w r g c | bww  |
+    | r g y c | w r g y | www  |

+  Scenarios: 2 colors correct
+    | code    | guess   | mark |
+    | r g y c | w g w c | bb   |
+    | r g y c | w r w c | bw   |
+    | r g y c | g w c w | ww   |

+    | r g y c | r w w w | b    |
+    | r g y c | w w r w | w    |
