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
