What makes this different:

In traditional block-stacking games, pieces fall downward and you clear horizontal rows. In Horizontal Block Stack, pieces fall sideways (left-to-right or right-to-left), and you clear vertical columns instead! This challenges your spatial reasoning and trains your brain to think in a completely different orientation.
