I'd read on the Mozillazine forums where someone raved on about a Tetris
extension for Mozilla/Firefox. After a quick search I realized there was nothing
similar for Opera users.
Now, I know there are already many implementations of Tetris in
Javascript. Did the world really need another one? Not really, but I
wanted to write one. Especially one that would fit into my Opera panels.
Add Tetris to your Opera
sidebar.
Notable features:
- Keyboard or mouse control.
- Green for 'go', orange for 'pause', red for 'stop'.
- Next shape preview.
- To offset the advantage of pausing, the shape preview is disabled for the
next couple of shapes.
- Speeds up the longer you play. Completing rows and dropping shapes slows it
down.
- Clearing more rows in one go gives you a bonus: one row has no bonus, two
rows fives you +5, three +15, and four gives you +30!
- Multiple shape sets that progressively activate the longer you play.
- High score saved in cookie.
- Totally self-contained, except for the big red 'O', which is read directly
from the Opera Software
graphics page.
- Uses random shades of 'Opera blue' for the shapes.
- Easy shape definition - add or suggest your own.
Note for Internet Explorer users.
