All/Some

All/Some turns the old Venn diagram question into a short daily puzzle. Each puzzle names a few groups of things, for example Birds, Insects and Things with wings, and offers several diagrams made of coloured circles. One circle can sit inside another, two can overlap, or they can stay apart. Your job is to pick the diagram that matches how the groups really relate: all birds have wings, some insects do, and no bird is an insect.

The puzzles come as a daily challenge built around a theme, such as unusual kitchen gadgets, and the home page counts down to the next one. Solving keeps a streak, and an anonymous account is created when you first open the site so your progress is saved; signing in with email, Google or Apple carries it across devices. Earlier days appear as tiles under the challenge, and themed collections on subjects such as general concepts and the animal kingdom sit alongside it.

The daily challenge is free for everyone. A paid membership, monthly or yearly, on the web or through the iOS app, adds thematic collections of over 100 puzzles in subjects like biology, history and mathematics, and opens the past week of daily challenges so a missed day can still count for the streak. The iOS app came out on 21 October 2026. All/Some suits players who like careful reading and small deductions more than word guessing.
