BlockDuel: a free falling-block battle game

BlockDuel is a quick two-minute duel. Pieces fall into your well; complete a full horizontal row to clear it. Clear two or more rows at once and you send grey garbage rows to your opponent's board, pushing their stack upward. They can do the same to you.

How to win

• Make your opponent's stack reach the top of their board, or
• Send more garbage lines than your opponent before the timer runs out.

Attack table

• Single (1 row): 0 lines sent
• Double (2 rows): 1 line
• Triple (3 rows): 2 lines
• Quad (4 rows): 4 lines
• Combo bonus: +1 line when you clear rows on 3 pieces in a row
• Board clear bonus: +4 lines when you empty your whole board

Defending

Incoming garbage shows on the red meter beside your board. Clearing rows before it lands cancels it out, so a fast double can block an attack. If you place a piece without clearing, all waiting garbage rises into your board.

Tips

• Keep one column open on the side and save the long piece for a quad.
• Use Hold to keep the long piece ready for the right moment.
• Keep the surface flat; tall spikes and covered holes are hard to fix under pressure.
• Steady doubles often beat waiting for a perfect quad.
