Grid Stacker

Grid-based stacking games are all about spatial patience. Leave flexible edges and the center open so larger pieces always have safe landing spots.

The same idea appears in TenTrix: the board gets hard only when you start solving placements one move at a time instead of thinking about shape traffic across the whole grid.

• Preserve broad placement lanes.
• Let the board breathe after clears.
• Avoid trapping yourself with decorative placements.
