Nintendo's version of Tetris for the NES/Famicom. Unlike the Tengen version, this game only supports one player (by default).

This is a complete reworking of NES Tetris into an original game called Threetris.

Yes, the more obvious (and possibly more appropriate) name would be Tritris. But there are already at least two games that use that name. (Though they are based on completely different ideas.)

Threetris is one of the first Tetris games that uses different pieces that actually ends up being (almost?) as fun as regular Tetris. You can find out more in the ReadMe about why these pieces in particular were used.

You will likely notice that you have to use the bottom 5 new piece shapes to fix problems that the top 2 new piece shapes create. There are at least two good strategies that offset that; but those will be up to you to discover.

After some practice you should be able to clear Level 9 Height 5 somewhat consistently.

Update V1.1: Fixed a minor graphical error.
