Optional equipment required. Have fun!
These drills require shooting tiles or an equivalent slick surface. I'm using a 2'×4' dry erase board (~$10) with WD-40 (~$5) applied, to keep it slick.
Attempt 5 each. Gold = 5/5 · Silver = 4/5 · Bronze = 2/5
3 combos. Gold = Group 1 (1 of 3) · Silver = Group 2 (1 of 6) · Bronze = Group 3 (1 of 9)
