Shapes and numbers

Study the board
Study the fixed numbers and empty spaces before moving a block. Look for room that matches its shape and clues that support the numbers it carries.

Choose a block
Choose a numbered block from the tray. Follow its shape and values, then compare both with the available spaces and clues before you settle on a position.
