Connection!
One stroke, every dot, no lifting - the whole rule set fits in a sentence.

One stroke, every dot, nothing lifted: that is the entire rule set, and it is enough to keep a board unsolved for several minutes. A longer explanation of the rule sits in Mahjong Rules for Beginners.
TuuT describes the aim as finding the best pathway to complete a shape, one stroke at a time, and the difficulty sits in the ordering rather than the dexterity. The rule that bites is the single touch — every dot has to fall on one continuous path, so an early turn into the wrong corner strands whatever was left behind it. The board runs at 800 by 600 and is single-player throughout. Kitchen keeps company with this board in the catalogue.
Players who solve these quickly tend to begin at an edge rather than the middle, because the two ends of a stroke are the only places a path is allowed to stop. Restarting costs nothing but the seconds already spent, which is why a failed line usually teaches you the route. The same heading covers the Jungle Jewels Connect layout as well.

How to Play
- Look over the dots and the paths that link them.
- Press down on a starting dot and keep the touch or click held.
- Trace one continuous stroke through every dot on the board.
- Release when the shape is complete, or restart and try a different entry point.
Tips & Tricks
- Start at an edge — a Connection board is easier to finish when the stroke begins where fewest paths meet.
- One touch only — the stroke cannot be lifted and resumed mid-shape, so plan the whole route first.
- Restart early — the moment a dot is stranded, that attempt is already lost.
- Watch the shape — TuuT frames each level as completing a shape, and the outline hints at the right pathway.
