Block Puzzle

Place the pieces. Fill a row or a column and it clears.

How to play

Three pieces wait under the board. Drag a piece onto the board, or tap it and then tap where you want to place it.
While you carry it you see the squares it will take; if it does not fit there, it goes back to the tray.
Fill a whole row or column and it clears: 100 points for one line, far more for several at once.
A new set of three comes only when all three are placed. The run ends when none of them fits.
