How to create a normal running program? Because my program is run eternaly and wont stop – CentOS

My English is very bad, but i’m try to explain my problem.
I want to create a small program on bash in which the user will have to guess the numbers. But my program has no end.

I’m novice on bash scripting, but i try to get better everyday.
I’m using CentOS 7. I go to /usr/bin/local and create some file, give him chmod +x and open with gedit:

#!/usr/bin/bash

#This script should ask us our name and play the game "Guess the Number" with us.

echo "What is your name?"
read name
echo "Hello $name"
echo "I want to play $ name with you, you have to guess the number from 1 to 10)"
echo "Are you ready?"
read rdy


answer=$(( answer = $RANDOM % 10 ))


read -p "Enter your number: " variant 
     while [ $answer != $variant ]; do

if [ $answer -gt $variant ]; then 
     echo "Your number is bigger, try again"

elif [ $answer -lt $variant ]; then
     echo "Your number is smaller, try again"

  continue

fi

done

eternal "Your number is smaller/bigger"
until you press ctrl+c

What I need to do, please help. I know non amateurs don’t likes novices but i need your help, show me my mistake, and i can get better. Thanks!

    You call

    read -p "Enter your number: " variant

    before the while loop.

    Inside the loop you never change the variant, so the original value is re-used in the while condition. For Eternity.

    You can start with variant=-1 and move the readinside the loop or do something like @xiawi.
