Gameplay (game rules) cannot be trademarked. They can only be patented. Patents last 20 years. Tetris came out in 1986. Tetris gameplay is not patented and can be copied.

I'm not sure about that. I think they re-issued the patents when the Tetris Company was founded. (In '96 I think?)

There is no patent on Tetris (or Asteroids, etc), so go ahead and copy its gameplay. You cannot use the art from any Tetris game, as it is copyrighted. You cannot use the name Tetris, as this is a trademark. Using the suffix "tris" is questionable...

Actually, I remember reading they trademarked several aspects of the gameplay, such as "puzzle using blocks made up of four squares falling down".

The Tetris Company sued Apple last year over their iPhone Tetris app, and did the same with the Android store not too long ago.

That being said, I think if you make it clear you're not making money with it / made it just for fun you should be fine, as long as it doesn't get to be super-popular and 100 000 people start playing it.

And either way, they're more likely to send you a cease-and-desist notice first rather than suing right away.

(By the way, yes, the USSR "stole" the rights to Tetris, but after the end of the Soviet Union the Tetris Company was founded - by the actual inventor of Tetris, I think.)

I love exe than applet. But love jar than exe Cheesy
when I paused, the gamed freezed because it's trying to obtain online score while my connection unplugged. That's all.

Whoops. Should probably look up how to implement a time-out thingy when it can't retrieve scores...

Why did you make a Windows and Mac version? It would be better to leave it as a Jar file so anyone can run it.
even better if it was an applet  Wink
Agh accidental apppreciate Tongue
But yes that would be nice too Cheesy

I have appletophobia :p

It's happened before that I sent people a .jar file and they asked me what to do with it / what program to run it with... I was just trying to be user-friendly  Grin

Love the backgrounds~

Nope, just plain old Java2D Smiley
A game loop, a CanvasStrategy and a whole bunch of BufferedImages and AlphaComposite settings. :p

Good to hear theres highscores! I like tetris a lot!  Cool

I got on a tenth-place with my 194?0 points..  Cheesy

Okay feedback!
1) The controls didn't feel accurate, because of the delay. Maybe you can increase the framerate to more to make the movement faster.
2) When turning a block while it is close to the borders of the game, I feel like it should rotate and just move horozontally so it can fit in there, instead of being unable to move.
3) Maybe a button to make it fall all the way instantly, and maybe markers to show where it'll land? It makes it a little easier Tongue
4) Make the blocks fall from higher above. It feels likeit's aready fell 1/3 when it's spawned Smiley

Highscores seem to give some more replay value to standard Tetris Wink

Thanks for the feedback:

1) I don't think it has anything to do with the framerate, more likely with KeyAdapter's automatic delay if you hold a key... do you have the same problem when you tap the keys instead of holding them? Maybe I should just switch to JInput...
2) I guess I could try that :p
3) Spacebar makes them drop instantly, I guess I could add markers as an option / bonus / easy mode.
4) The field actually adheres to the official size as specified by the Tetris Company (lol :p), it just seems like the pieces are lower because on a real Tetris field the first row is made invisible...

Now, to figure out sockets so I can whip up a PvP version...

Hi all,

Just thought I'd share a Tetris clone I recently (more-or-less) finished. You can take a look at it here:

Thanks for checking it out / leaving feedback Wink
