Logic-puzzle portals

One site, lots of genres. The quickest way to try something you haven't played yet.

How do I find a puzzle type I have never played?

Open All-in-one portals (19 sites on this page). One room often hosts many genres under one login-free door, so you can browse and try a type before you commit to a specialist list.

Who are all-in-one portals for?

Start here if you have not settled on one genre, or you like switching through the week. One site often covers dailies, a board and dozens of rule sets — many need no account. The trade-off is clutter, and a single type is rarely as deep as a specialist site.

How do I pick a portal?

Check that a type you already know is there (most people come in through Sudoku or Nonogram), then whether progress survives a refresh. Free, printable or offline-friendly sites suit a commute. Heavy ads or an app wall can wait.

Portals vs specialist sites?

Use a portal to discover; move to Sudoku, Japanese or solver pages when you want depth. Nikoli, Tatham and puzz.link feel like libraries. Sudoku.com feels like a daily habit.

How is this list ordered?

We put sites we actually return to near the top. Cards leave this site; rules and accounts belong to them.
