4 in 1 + 8 in 1 — About this game
Begin with one title and watch how its first screen explains movement and scoring. A different cartridge code can contain a different selection; use the actual menu as your guide. Complete a short attempt before changing games, then compare the next entry's rules instead of carrying over the previous controls.
