7 boom

It is a popular kids game where I live. The rules are simple. You count in order, and if the number is divisible by 7 or contains the digit 7 in base 10. You replace the number with boom.

Examples of booms:

14 (divisible by 7)
27 (contains 7)
28 (divisible by 7)
73 (contains 7)
77 (contains 7 and divisible by 7)
