Key ideas in Mastering the Falling Blocks

  • Prioritizing placements that leave the surface level
  • Deep wells can only be filled by specific pieces like the I-piece
  • Matching piece geometry to the existing surface contours
  • Jagged stacks create 'dependencies' where you must wait for a specific shape to avoid gaps
  • It is better to create a covered gap that can be cleared later than to build a 4-block deep hole
  • Avoid creating 'spires' (single tall columns) that split the board in two
  • Heuristics for placing a piece when no perfect spot exists
  • A 'well' must be exactly one column wide to fit the I-piece
  • Building a stable foundation prevents 'garbage' gaps
  • The rest of the stack must be at least four rows high to clear four lines at once
  • The I-piece is the only piece capable of clearing four lines
  • Recognizing the correct board structure for a four-line clear
  • The process of executing a four-line clear from an empty board
  • Survival (not topping out) takes priority over high-score efficiency
  • Clearing small lines reduces stack height and buys time for better pieces
  • Identifying which piece placement best maintains a flat surface
