I just have a question about where I can find a tutorial to explain the steps on how to make a game in java like tetris the best way.

I recently finished mine, but I know it really isn't the most efficient way and I was just curious to see if there are any tutorial sites out there that have a good tutorial on how to efficiently make games like tetris or anything else.

I don't know how much this would have specifically relating to making a game like Tetris, but for any general questions on the workings of Java, the official tutorial has a lot of helpful information.
