Hi @CATICABOOM, I can help you. 10x10 is a Tetris-like puzzle game. When presented with the puzzle pieces (below the grid), click cursor over the pieces then drag-and-drop the blocks onto the 10x10 grid. You will be given ("dealt") 3 pieces/sections at a time. Once you have created a full vertical or horizontal line, it will disappear.
10x10 Classic is not timed, so you may go at your own pace and enjoy! Does this help answer your question?
1) Select the puzzle pieces with your cursor and drag to the desired position on the board.
2) Place or "drop" the puzzle pieces on the board.
