Prevent user to check check box randomly using javascript

I have following test checkboxes. A user can select any checkbox in any order. My question is how I can use javascript/jquery to prevent user to select checkbox randomly. I would like user to click first checkbox, than second and so on.

​1 <input type="checkbox" name="sports" value="1"  /><br />

2 <input type="checkbox" name="sports" value="2"  /><br /> 

3 <input type="checkbox" name="sports" value="3"  /><br /> 

 4 <input type="checkbox" name="sports" value="4"  />

I need help writing script that would only allows to check each of the chckboxx in order - left to right.

Many Thanks in advance
