Under Construction is a modern take on the classic Tetris game, where you have to construct various shapes and objects with building blocks that speed along a conveyor at too fast a speed! The idea is to construct the object without leaving any holes, so you have to think quickly and click and drop the construction blocks into place before they disappear off your screen. To play this Under Construction game left mouse click on the piece click again or use your space bar to rotate the construction block and press your left hand button to place the construction block on the grid. You can change pieces by dropping them in the bin and use your power up tools to fill in gaps and knock new holes.
