All Dot Connect Puzzle Game

All Dot Connect Puzzle Game, which the developer also refers to as One Line with One Touch, has a single rule. Every dot on the board must be connected, and all of it has to happen in one touch: press down once and draw the whole thing before you lift off.

The puzzles come grouped into packs, and the developer mentions a good number of them. There is also a daily challenge for anyone who wants a fresh puzzle each day. The pitch is brain training in small doses, a couple of minutes a day, played at home, at work or on a bus. With rules this short, each puzzle differs mainly in its layout, which is where all of the thinking happens. It can be played with the mouse on a computer or by swiping on a touch screen, in a landscape frame.

Press on a dot with the left mouse button, or touch it on a screen, and swipe from dot to dot to draw lines between them. The aim is to connect every dot on the board in a single touch, so keep the movement going until the final dot is joined. Pick a puzzle pack, or try the daily challenge.

With only one touch allowed, the route has to be settled in your head before you press down. Choose a likely first dot and follow the lines mentally all the way to the end. If some dot is left stranded, the problem is usually where you began, so test another starting dot.

A one-touch dot-connecting puzzle. Landscape frame (800 by 600). Mouse and touch controls. The developer mentions many puzzle packs and a daily challenge, and frames the game as short daily brain training.

Dots Line asks you to connect every point without lifting off or drawing any line twice, and Link Flow has you join dots until your lines recreate a target pattern.
