Block Puzzle Magic

You’re given a fixed grid (often 10×10) into which you must place (drag) blocks of various shapes. You drag block pieces from a preview area and drop them onto the grid. You have to find space where the block fits. When you completely fill an entire horizontal row or vertical column with blocks, that entire row/column clears out (is removed), and you score points. You cannot rotate the block pieces — they must be used in the shape presented. Because the blocks come in various shapes, you need to plan placements intelligently so you don’t block yourself from placing future pieces. The game ends when there is no more space to place any of the current block pieces. When none of the available block pieces can fit anywhere on the grid, the game ends. Your final score depends on how many rows/columns (and combos) you cleared
