A single-line clear keeps you alive. A combo in Block blast (clearing 2, 3, or 4+ lines with a single piece) skyrockets your score and dramatically cleans your board. Combos are rarely lucky; they are engineered.

TL;DR

• Plan combos by building multiple lines that are 80-90% complete.
• Identify "keystone" spots where one block will intersect and complete multiple lines.
• The "T-Slot" and "L-Corner" are your best friends for setting up combos.

Common Combo Setups

1. The Double Dip: This is the most fundamental combo. Set up one nearly-complete row and one nearly-complete column that intersect. Find a piece (like an L-shape or T-shape) that can fill the intersection point and complete both lines simultaneously.
2. The Cascade: Build two or three parallel rows (or columns) that are each missing just a few blocks. Wait for a long, straight piece or a well-placed square to clear them all at once.
3. The T-Slot: Create a T-shaped hole in your structure. This setup is a magnet for combos, as both T-blocks and L-blocks can often clear multiple lines when placed here.

Thinking in "Lines to Completion"
Instead of just looking at empty space, train your brain to count how many blocks each row and column needs to be complete.

• "This row needs 2 more blocks."
• "This column needs 1 more block."
• "If I place the L-block here, it will finish the column and leave the row needing just one more piece."

This mental calculation helps you see combo opportunities before they fully form.

Drills for Seeing Combos

• The "Combo-Only" Game: Play a game where you try to score points only from multi-line clears. It will be a short game, but it will force you to ignore single-line temptation and focus entirely on setups.
• Pause and Plan: Before placing any set of three blocks, pause. Verbally identify the best possible combo setup on the board, even if you don't have the pieces to complete it yet.

Pro Tip
The setup for a combo is often the "ugliest" placement in the short term. You have to be willing to make the board slightly worse for a turn or two in order to achieve a massive payoff.
