Start with a rule you can hold in your head
Two tiles make ten. A path hits a target. A loop has to close. Each family is one relationship, written in numbers, not in lore.
No ads. No subscription.
Fill a board so every relationship is true. Daily, Weekly, and Quick are free. Full Game is one purchase, yours.
Built for people who like puzzles
Numberfold is local-first. You do not need an account to play Daily, Weekly, Quick, or the starter families. There are no ads, and nothing renews. How-to lives on the information icon during play, not in a five-screen onboarding.
01Pairs
Two tiles make ten. A path hits a target. A loop has to close. Each family is one relationship, written in numbers, not in lore.
02Families
Path, Ten, Sequence, Between, Pairs, Missing, and the rest. Starter families are free on easy and medium. The others wait behind Full Game or a pack.
03Daily and Weekly
Daily and Weekly are always free. They do not expire into a paywall, and they do not ask you to keep a streak alive.
04On the device
Progress lives on the phone unless you choose to copy it. A website or Mac purchase unlocks those clients. iPhone and Android purchases restore with Apple or Google, and stay on those stores.
05Quick
Target and Even/odd are free. The rest of Quick unlocks with Full Game. Short enough to finish standing in a doorway.
06Full Game
Full Game is the base catalog, forever. Expansion packs are extra families, still one-time. Nothing here is rented.
