1. Keep the center of the grid open
A block in the middle gets in the way in four directions. Work inward from the edges and corners, and treat the center as a reserve for awkward shapes.
2. Plan the whole tray before placing one piece
Find a home for every piece in the tray, then decide the order. Rounds often end with one piece left over because the earlier ones were placed without a thought for it.
3. Place the hardest piece first
The largest shapes are the ones that end rounds. Put them down while the board is at its emptiest, then fit the small pieces around them.
4. Always keep one large gap
If the biggest shape has nowhere to go, you're one unlucky tray from losing. Protect an open square area, and a straight run for a long bar.
5. Don't leave single holes
One empty cell walled in by blocks can only be filled by a one-square piece. Until then it keeps its row and its column from clearing. Build in solid rectangles so the gaps stay wide.
6. Clear two lines with one piece
Combos earn extra points. Build two nearly complete lines that share a gap, a row and a column for example, then fill the gap.
7. Take the safe clear when the board is tight
A combo set-up that leaves the grid nearly full is a gamble. When space is short, take the single clear. Build combos when there's room.
8. Slow down at the halfway point
There's no timer on the board, so thinking costs nothing. The moment to think longest is when the grid is about half full, because that's where rounds are decided.
