Who the hell proved that? And how?
In other news, I've been replaying Canabalt
these days. It's
unfair how it sometimes presents you with impossible obstacles.
For any size game, there is some number of R or Z tetraminoes that will fill the level, since you cannot clear anything with ONLY those. Any random sequence of sufficient length will contain that number (and more) R or Z tetraminoes. The key is getting only R or only Z for long enough to fill the level.
Disproof by counterexample.
Consider a game with only Z-tetraminos (my diagrams use S-tetraminos because I read the post wrong, but the same idea applies).
First arrange them like so (state A):
Notice that the second row gets destroyed, producing the following (state B):
Now add another bunch like so (state C):
Notice when it's collapsed you return to state B and thus, an infinite loop:

is pretty much amazing and you should all play it.
