The mother of a 7-year-old boy managed to score the kid a sick birthday gift ... courtesy of The Game.

Darkima Johnson tells TMZ she was with her son Jaden last Thursday to celebrate his 7th birthday at the Lenox Mall in Atlanta. Darkima says she spotted Game out front and asked for a photo ... and explained it was her son's b-day. 

That's when Game decided to count out seven $100 bills and hand them over to Jaden ... despite the fact Jaden had no clue who Game was. 

Jaden's mom tells TMZ she's planning on getting him a four-wheeler with the money.

Hate it or love it ... that's a dope gift.
