A closer look
1010 Sudoku combines block placement with the three by three regions associated with Sudoku. You drag shapes onto a grid and aim to fill rows, columns or those smaller regions. The appeal is spatial: a placement changes the room available for the next shape. Choose this when you want to think about how pieces fit together rather than which digit belongs in a cell.
How to play
Look at the available blocks and the open areas of the grid. Drag a block into a place where the whole shape fits. Aim to complete a row, column or three by three region, then examine the resulting board before choosing your next placement. Avoid treating every piece as a separate decision. Think about the spaces that remain and compare a few possible positions before committing to a move.
Think one move ahead
Each piece occupies several cells, so its effect reaches beyond a single square. A promising position may advance a row while also helping a column or region. Look across the board for places where those opportunities overlap. At the same time, pay attention to the empty spaces left behind and whether they remain useful for placing blocks.
