+# Instructions
+
+Score a bowling game.
+
+Bowling is a game where players roll a heavy ball to knock down pins arranged in a triangle.
+Write code to keep track of the score of a game of bowling.
+
+## Scoring Bowling
+
+The game consists of 10 frames.
+A frame is composed of one or two ball throws with 10 pins standing at frame initialization.
+There are three cases for the tabulation of a frame.
+
+- An open frame is where a score of less than 10 is recorded for the frame.
+ In this case the score for the frame is the number of pins knocked down.
+
+- A spare is where all ten pins are knocked down by the second throw.
+ The total value of a spare is 10 plus the number of pins knocked down in their next throw.
+
+- A strike is where all ten pins are knocked down by the first throw.
+ The total value of a strike is 10 plus the number of pins knocked down in the next two throws.
+ If a strike is immediately followed by a second strike, then the value of the first strike cannot be determined until the ball is thrown one more time.
+
+Here is a three frame example:
+
+| Frame 1 | Frame 2 | Frame 3 |
+| :--------: | :--------: | :--------------: |
+| X (strike) | 5/ (spare) | 9 0 (open frame) |
+
+Frame 1 is (10 + 5 + 5) = 20
+
+Frame 2 is (5 + 5 + 9) = 19
+
+Frame 3 is (9 + 0) = 9
+
+This means the current running total is 48.
+
+The tenth frame in the game is a special case.
+If someone throws a spare or a strike then they get one or two fill balls respectively.
+Fill balls exist to calculate the total of the 10th frame.
+Scoring a strike or spare on the fill ball does not give the player more fill balls.
+The total value of the 10th frame is the total number of pins knocked down.
+
+For a tenth frame of X1/ (strike and a spare), the total value is 20.
+
+For a tenth frame of XXX (three strikes), the total value is 30.
+
+## Requirements
+
+Write code to keep track of the score of a game of bowling.
+It should support two operations:
+
+- `roll(pins : int)` is called each time the player rolls a ball.
+ The argument is the number of pins knocked down.
+- `score() : int` is called only at the very end of the game.
+ It returns the total score for that game.

+# Gradle start up script for POSIX generated by Gradle.
+#
+# Important for running:
+#
+# (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
+# noncompliant, but you have some other compliant shell such as ksh or
+# bash, then to run this script, type that shell name before the whole
+# command line, like:
+#
+# ksh Gradle
+#
+# Busybox and similar reduced shells will NOT work, because this script
+# requires all of these POSIX shell features:
+# * functions;
+# * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
+# «${var#prefix}», «${var%suffix}», and «$( cmd )»;
+# * compound commands having a testable exit status, especially «case»;
+# * various built-in commands including «command», «set», and «ulimit».
+#
+# Important for patching:
+#
+# (2) This script targets any POSIX shell, so it avoids extensions provided
+# by Bash, Ksh, etc; in particular arrays are avoided.
+#
+# The "traditional" practice of packing multiple parameters into a
+# space-separated string is a well documented source of bugs and security
+# problems, so this is (mostly) avoided, by progressively accumulating
+# options in "$@", and eventually passing that to Java.
+#
+# Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
+# and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
+# see the in-line comments for details.
+#
+# There are tweaks for specific operating systems such as AIX, CygWin,
+# Darwin, MinGW, and NonStop.
+#
+# (3) This script is generated from the Groovy template
+# https://github.com/gradle/gradle/blob/HEAD/subprojects/plugins/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
+# within the Gradle project.
