Sequence asks for order; visual grid asks for locations without order. Number recall uses typed digits; number order uses hidden positions. Verbal memory asks whether a word appeared earlier in the run.
Your best belongs to that challenge and this browser. There is no combined memory score or population comparison. For a task about responding to a cue, try the reaction time test.
