Mini-mission

Bring the pieces together: a welcome message, a starting score and a score after a round reward.

Use only print instructions, text, numbers, a local variable and an addition update. Keep each result on its own line. Your project stays here when you finish.

Your task

Print your own welcome message. Create a local score starting at 10 and print it. Update that variable by adding an 8-point round reward, then print 18. Three output lines: message, 10, 18. Print the same variable directly at both observations. Use straight-line print calls, local values and updates for this exercise. The required calculation or variable must supply the displayed value; unused code does not count.

Output requirements

Your message is your choice. The checker reads actual output and value types; the reference wording is not required.

How your work is checked

The required syntax is stated in Your task. The Luau parser checks for local-variable, assignment, local-read, addition, same-local-before-after; the output check verifies the stated result. It does not trace every intermediate variable value.

Syntax in this activity

This activity reuses syntax you have already met.

What this exercise checks

Actual Output · the stated behavior · extra output forbidden.

Successful execution is required. A compile error, runtime error or execution limit never completes this task.

Whitespace, matching single or double quotes, and different variable names are allowed. Output-only tasks accept any valid Luau solution meeting the displayed result and value types. Construct tasks use the stated straight-line form.

Lesson requirements: local-variable, assignment, local-read, addition, same-local-before-after. These are exercise requirements, not Luau syntax rules.
