Families
Cross is the Numberfold board, and it stays free. Path, Ten, Sequence, Between, Pairs — starter types stay free on easy and medium. Unlock Full Game when you want the whole room, or pick a pack for a new family of rules.
Daily and Weekly
Daily and Weekly never expire into a paywall. When you want a longer session, Mix strings your favorite types into one quiet run.
