Sometime vs. Some Time vs. Sometimes
“Sometime” most often points to an unspecified time, “some time” refers to an amount or period of time, and “sometimes” means on some occasions. The spacing and final -s therefore mark different time concepts rather than interchangeable spellings.
Use “sometime” for an unspecified point of time, “some time” for an unspecified amount or period of time, and “sometimes” for frequency—on some occasions. Context matters more than a simple one-word/two-word slogan.

Quick tests
Time-question test
Are you asking when, for how long, or how often?
If yes: When → sometime; duration/amount → some time; frequency → sometimes.
If no: Read the sentence for whether “some” directly modifies the noun “time.”
Caveat: Use this as a core-meaning diagnostic, not as a substitute for parsing the sentence: “some time” can be modified as a noun phrase, while “sometime” and “sometimes” serve different adverbial functions.
Examples
Let’s meet sometime next week.
Sometime means at an unspecified point.
It took some time to finish.
Some time refers to a duration.
I sometimes walk there at night.
Sometimes expresses frequency.
Further guidance
Some Time
Use some time when “some” modifies the noun time—an amount or period that can often be replaced by “a while” or “a long/short time.”
Sometime
Dictionary.com notes that sometime is commonly one word when it means an unspecified time, often future.
Sometimes
Sometimes is the frequency form: it answers how often by meaning on some occasions.
