Konductra is a puzzle game for the Nintendo DS published by O~3 Entertainment. The game had an interesting development cycle, with IGN revealing the title on November 23, 2005. At the time independent developer oeFun had started work without having a publisher lined up. oeFun and O~3 came into a publishing agreement in the summer of 2006 after the title was finished. Multicoloured pairs of tiles have to be placed on a grid that is lined with 'conductors' by using the DS's stylus, with the aim of creating rows or blocks of the same colour. Once a row of tiles reaches the edge of the board, the pieces can be removed by drawing with the stylus through a conductor and along the chain. The game is also Nintendo Wi-Fi Connection enabled. A sequel titled Konductra: Graveyard Shift was released for download on the Apple iOS on July 18, 2013. Gameplay Players destroy lines by matching tiles and using the stylus to trace from like coloured conductors running along the four edges of the screen. The bottom touch screen is where the game is played. The top screen shows integral information about the game being played. The built-in tutorial, with speech, offers an overview of game basics. There is a timer that counts down as the piece is being positioned, and if the tile is not placed on the grid by the time the countdown reaches zero, the piece is automatically put on the board as a "block" tile. These "blocks" can only be removed by being conducted in a chain twice, as opposed to just once for a normal token. Modes include: Score: Using the top screen as a reference for potential points, players aim to get a high score. When a line is destroyed, players are awarded the points shown on the top screen, while getting multiple lines multiplies the score shown. At levels 5 and 10, new coloured tokens are introduced. Task: Match the shape shown on the top screen. Once the shape has been successfully duplicated, it must be destroyed to win. There are 66 tasks that can be unlocked, but they must be completed in order. The mode is used to introduce techniques for more complex methods of play. VS Human: Play against another human using the Nintendo DS wireless feature. The object is to beat your opponent by keeping your board clear while simultaneously filling
