The most simplest tetris game with jgamegrid as a library

I want you to build me a java tetris game with the jgamegrid library. This tetris game is kind of different. Instead of the blocks falling to the bottom, the blocks respawn from the bottom and fall to the top. Only use three types of different blocks for tetris. (see pictures: I-block, L-Block and J-Block) I've already done a part of it and I want you to help me. Cause somehow I can't finish it... I've already have the background and the sprites that can be used. I've already coded how to control a simple I-block of tetris but I'd like you to help me out. As you can see I am a beginner and you also have a minor role as a teacher. Anyway, programm it in simple language (please copy everything from the library and its tutorials because I need to learn how to use a library.) In short, you can and have to copy everything from the library and it is fairly easy. -> respawn of the block -> control the block (right - left - turn) -> make the block stop at the top -> delete a line in tetris if there is a full line -> move up the remaining blocks -> stop the game once it reached outside of the gaming field
