Pipe Dream

The player has several seconds before the flooz starts flowing from its starting position to place the pieces. They can be placed anywhere on the grid, but a gap may remain to be filled, requiring the player to replace a piece with another to make it easier for the flooz to flow through that square. The player can also earn bonuses by looping the flooz through both sides of at least 5 cross-over pieces or passing the flooz through every square on the screen.

Later levels introduce new challenges, such as blocked squares and gaps in the side-wall, which allow the flooz to thread to the other side of the screen. After every four levels, there is a bonus game where the player can only place pieces in the lowest open space in each column, similar to the board game of "Connect 4".
