One username for every JabMed game
Sign in once on jabmedmedia.com. The same name carries progress in Plankwalk, The Chart Room, and Critical Mass.
You can now use one username across the free games on this site.
Join or sign in from Plankwalk, The Chart Room, or Critical Mass. The name is the same account. Charts, lab notes, and plank progress stay with that name when you hop between games (or pick up on another device).
Guest play still works. Nothing is required to start a voyage — sign in when you want the name to follow you.
Currencies stay in their own games. Doubloons do not buy reagents. The shared piece is the username, and the progress attached to it.
