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.
Thanks for your question, @jm69025472. One of the fun and challenging aspects of 10x10 is that you cannot rotate the pieces. Instead, you must play them as-is, in the direction they are presented. It definitely gets tougher to find open spots for pieces as the game progresses. Try to focus on completing full rows so that they clear out and open more space. It's easy to make the mistake of boxing in a single open square by surrounding pieces. It seems you get less and less one-square pieces to play as the game goes on, but that’s the challenge!
