How to Consistently Set Up Triple and Quadruple Line Clears

The cross-clearing blueprint

The most reliable way to clear multiple lines is through the Cross Intersection: preparing a horizontal row and a vertical column that both need a single mutual square.

Dropping a single block into that intersection clears both lines at once, triggering an immediate 2x combo multiplier in <a href="https://apps.aagyasharma.com/blockflow/">Block Flow</a>.

Preparing the triple clear

To achieve a triple or quadruple wipe, construct two parallel rows and one intersecting column. When your piece drops, the board collapses in a spectacular cascade.

• Identify shared intersection squares early.
• Do not close a line prematurely if a cross-clear is one turn away.
• Use the Undo booster if a piece blocks your cross-clear channel.
