Why L-shapes disrupt flat surfaces

Unlike straight bars or rectangular dominoes, an L-tromino (or tetromino) introduces a concave inner corner. Placing it against an existing flat wall instantly creates an empty, isolated single-tile cavity.

In <a href="https://apps.aagyasharma.com/blockflow/">Block Flow</a>, nested cavities are difficult to fill unless a lucky 1x1 block arrives.

The Corner Docking Rule

Always nestle L-shapes into outer corners or interlock two complementary L-shapes to form a solid rectangular footprint.

  • Never face the concave corner of an L-piece toward an open board edge.
  • Pair complementary elbow pieces to form clean 2x3 or 2x2 blocks.
  • Use the outer board perimeter to absorb protruding corners.
