This is an obscure tip, but one of the cool features of top-rated Platinum Sudoku is the ability to draw the numbers with your finger. However, some of drawings don’t always translate correctly. Drawing a number 5, in particular, is troublesome. To create the number 5, draw the two shapes like in the picture above. Make sure to draw them quickly, else it will falsely recognize only the first shape.

The rest of the numbers pretty much work exactly as they are normally written, although I find the number 4 sometimes troublesome as well. See picture below of a number 4 that translated correctly as well.
