Dots Master

Dots Master is played on a board of coloured dots. You link neighbouring dots of the same colour by dragging between them, moving up, down, left or right. Only straight steps are allowed, so diagonal neighbours cannot be joined. Close the link into a square or a loop and every dot of that colour on the board is cleared in a single move.

Each level sets its own target. The developer lists several kinds: clearing a set number of dots of a given colour, popping stars, making loops and taking over tiles. All of them have to be achieved within a limited number of moves, which makes every drag count. The game is divided into five chapters, and four power-ups are named: extra moves, bombs, shuffle and auto-loop.

Tap a dot and drag to an adjacent dot of the same colour, going vertically or horizontally, to connect them. Carry on through further matching dots to extend the link. Bring it round into a square or loop to clear every dot of that colour at once. Complete the level's goal before your moves run out.

Squares and loops are the strongest move the game describes, because they clear an entire colour together. On levels whose goal is to make loops, that same move is exactly what the level asks for. Extra moves are among the listed power-ups, which is useful when a goal is nearly met just as the count runs out.

A dot-linking puzzle with move limits and level goals. Portrait frame (540 by 720). Tap-and-drag controls. The developer lists five chapters and four power-ups: extra moves, bombs, shuffle and auto-loop.

Catch The Hen: Lines and Dots also works by connecting dots, though there the lines are used to surround hens, and Dots and Boxes 2 has you draw lines between dots to complete boxes.
