Casual Puzzle & Card Games: Pour, Block Fit, Solitaire 🃏
Published: August 10, 2026 · 4 min read
Not everything has to be a workout. Three games in the hub are built for the state where you want something to do with your hands while you think about something else entirely.
Pour — water sort
Tubes of coloured liquid, poured one into another until each tube holds a single colour. You can only pour onto a matching colour or into an empty tube.
99 levels, and the difficulty comes entirely from how many spare tubes you have. With two spares it's a gentle shuffle; with one it becomes a real planning puzzle, because every pour you make forecloses another. Undo is unlimited. Full guide →
Block Fit
An 8×8 board and three pieces at a time. Place them anywhere they fit — no gravity, no rotation — and clearing a full row or column removes it.
The absence of rotation is the design decision that makes it. You can't wriggle out of a bad board with a clever spin; you have to have left the right hole open three moves ago. 21 piece shapes. Full guide →
Solitaire
Klondike, draw one. Build four foundations from ace to king, endless deals.
Draw-one is the forgiving variant, which is deliberate — this is the version you play while listening to something, not the version you play to suffer. Roughly four out of five Klondike deals are winnable in principle; whether you win them is another question. Full guide →
Why low-pressure games earn their place
There's a real difference between a game that demands your full attention and one that gives your hands a job. The second kind is what most people actually want at 11pm, and pretending otherwise is how puzzle apps end up feeling like homework.
None of these three have a timer. None of them can be failed in a way that costs you progress. Pour and Block Fit have unlimited undo; Solitaire deals you a new hand whenever you want one.
It runs in your browser, works offline once loaded, needs no account, and costs nothing.
Questions people actually ask
Is every water sort level solvable?
Yes. Levels are generated by shuffling from a solved state, so a solution always exists — and undo is unlimited if you paint yourself into a corner.
Which solitaire variant is this?
Klondike with draw one, the most common and most forgiving variant.
