The deceptive simplicity of the square
Straight line bars appear intimidating because they stretch across five cells. However, a bar only requires a single open dimension: one straight row or column.
In contrast, a 2x2 or 3x3 square demands simultaneous width and height. In <a href="https://apps.aagyasharma.com/blockflow/">Block Flow</a>, a board with jagged single-tile gaps has plenty of room for lines, but zero legal footprints for solid squares.
The 3x3 Sanctuary Principle
Always keep one 3x3 corner open on your board. Even when chasing aggressive combos, never let an isolated tile invade your designated sanctuary zone.
A single misplaced cube inside your 3x3 sanctuary can end a 15,000-point run within two moves.
