Pair-up with someone around the same stature and elect who will start as tagger (A) and dodger (B). Assign 1/6 of court space. Players face one another, reach out and touch fingers - this is how far to stand apart by default.
On 'go!', (B) must always be on the move - no standing stationary.
(A) and (B) move around the court like boxers squaring off in the ring. At any time (A) can attempt to tag (B)'s leg. (B) uses fast footwork and evasive action to avoid being tagged.
(B) should very watchful of (A)'s leg shaping into a lunging position
(B) cannot 'swat' away the arm, only use footwork to avoid
(A) should remain upright to avoid head collisions
If (A) manages to tag (B) on the leg, they get a point and continue
(A) keeps score of their tags by calling-out their tally after each success
Continue for a set time between 45-60 seconds, then change roles.
New tagger (A) must attempt to beat the score.
