The easiest way is to have an array that represnts the game area. each element of the array will be a square. Then have values for the array elements that represent the different states a square can be.
Typically
0 = blank square
1 = moving square
2 = stationary square

Then just have a function that draws a representation of the array to the screen, Just paste a copy of the square image where there is a 1 or 2.

A function that moves all 1s down until the shape hits the bottom or a stationary square(2).

A function that checks for completed lines and removes them as well as moving all squares above the completed line down.

A function that checks to see if there are no moving squares(1) and if there are none spawns a new piece at the top.

You can use the code on my site if you want. I wrote it quite a while ago and can't remember what state it is in. It might not be very readable or understandable.

Click the source button for some minimal tetris code. It only has one shape (square) and only has code to move the square and move it down the screen. It should show enough to get you started
