About Block Spark
Fit colorful blocks into an 8 × 8 board, clear lines and build combos. Collect copy bonuses and charge Spark to play with crystal blocks that can overlap the board. Start with a guided practice and discover more shapes as you play.
How to play
Follow the guided practice on your first play, or reopen it from ?. Drag blocks onto the board, or tap a block then a square. Complete any row or column in any colors to clear it. Use all three blocks to receive a new set. More shapes join the mix as you place blocks. Consecutive clearing moves build a combo up to ×5. Each normal placement adds one Spark charge. Cover lightning to collect its shown charge. At full charge, blocks turn into blue crystals and can overlap occupied squares; lines clear on the final Spark move. A copy marker appears every 250 points: cover it to get the same block back in its slot. Collecting copy or lightning bonuses preserves your combo. You have two New blocks uses per round. The round ends when none of your remaining blocks fit. Keyboard: select the board, press 1–3 to choose a piece, arrow keys to aim and Enter to place.
