+# Guess A Number (Task 1)
+
+## Project Overview
+
+The goal of the first project is to program a simple number guessing game: the player needs to correctly guess a number, chosen from an interval, with at most guesses.
+
+In the lecture, a first version of the game was presented, in which the player had only one chance of guessing the correct number. In order to implement the full game, you will have to extend this version by allowing the player to guess up to times.
+
+The first project consists of two tasks: task 1 (this task) is to reimplement the first version of the game that was presented in the lecture, task 2 is to implement the full game.
