Those are the studio's own words, reproduced as we received them and not checked by us. The feed occasionally describes a different game altogether, so treat it as a starting point rather than a fact.
We have not written about Block 21 ourselves yet. Every game we cover is taken apart and played first, so this page waits until that happens. The game above works either way.
