Connectris

DOSGames.com Review:  Rating: 3.5
Connectris is an interesting mash-up of Tetris and Pipe Mania. Square pipe blocks fall from the top of the screen, and you must rotate them and place them carefully to connect each pipe to form complete loop circuits. No piece may be placed in a manner where it cannot be connected to another piece, if you do, the level is instantly over. The game is actually fairly unique (I don't recall ever seeing a similar concept) and it plays pretty well, although it may take a few minutes to pick up how everything really works. (See the "Information" menu option and read it carefully.) The game gives you extra incentives to build your stack high before finishing the level by providing score bonuses. Average graphics for a puzzle game. Definitely one to check out if you're into Tetris, Pipe Mania / Pipe Dream and/or puzzle games in general.
