Classic Tetris Game Put the falling parts in such an order that they fit together, with the least amount of spaces. As soon as you have any horizontal row, that row will disappear and be counted. To move left or right use the left and right arrow keys. To rotate a figure use the "up" arrow key. To make the figure fall down faster, press the "down" arrow. A good way of keeping control over the game is to put matching pieces in such an order, that the next available figure will fit in the gap made.
Try to keep everything from building up all the way up to the top. If you reach the top, the game is over. There is one "helper" piece - a small square which flashes. Use it wisely, as it can clean up one whole vertical row. If you have spaces buried underneath somewhere, you can drop the flashing square there. In the right top corner you can see what the next piece will be, and plan how to align the current piece to better fit the next piece.
