Most daily puzzles ask you to find a word. All/Some asks you to find a shape. You get a handful of categories — and your job is to work out how they overlap and build the diagram that fits, one step at a time.
What it is: a daily logic puzzle about how categories relate. Who made it: Stephanie Simoes and Igor Grechishkin. What it costs: nothing, and there is no account. Play All/Some.
An Euler diagram is the one you have already drawn without knowing its name: overlapping blobs showing which things belong to which groups. It looks like a Venn diagram and is not quite one. A Venn diagram draws every possible overlap whether or not anything sits there; an Euler diagram draws only the overlaps that actually exist. So the empty regions are missing rather than empty, and the shape itself carries the claim.
That is what makes it a puzzle rather than a drawing exercise. Deciding that one category sits entirely inside another, or that two touch but never fully overlap, is the answer. You are not describing your reasoning afterwards; the diagram is the reasoning.
We are describing the design here, not reviewing it. SlowDen does not score games and counts no plays, so we have no basis for telling you it is good — only for telling you what it is.
The developers say the puzzles run from everyday concepts to topics in science, history and literature. That matters for a daily format more than it might sound: a puzzle that only ever tests one kind of knowledge becomes a vocabulary test, and you either have the word or you do not. Rotating the subject means the thing being tested stays the relationship, not the trivia.
It also runs in a tab. No install, no launcher, no account — which is the entire reason a daily habit can survive on a school or office machine at all.
All/Some is one of 102 games on SlowDen's community shelf — games sent in by the people who made them, as opposed to the partner catalogue. We did not make it, fund it, commission it or endorse it. It is listed because someone submitted it and it works. It was made by two people, which is worth saying plainly: Stephanie Simoes and Igor Grechishkin.
If you build browser games, that shelf is open: submit your own game. For more in this series, we wrote about a drawing game judged by an AI and a three-year ball python genetics demo. If you want the wider shelf rather than one game, there is our roundup of daily puzzle games.
