Dynamic Lines

You know the classic Lines rules: Try to clear the board, while those colour balls keep appearing on it. You put them in lines, and they blow up. You don't - and a few more jump onto the board. We, however, added something new to this game, to make it a bit more dynamic, as the title says. The balls do not wait for your moves, but appear every few seconds. It is probably the good idea to train for a little while with standard mode, before plunging into the dynamic one. To add some kind of contest, your results can be saved on the web server, and would appear in the Best Scorers table.
