Here's the second puzzle. It's also rated as easy difficulty, like the first one.
Again, this puzzle either runs inside the web page, as it should be doing now, or you can use the "Float Window" button to popup a new window which you can make bigger or smaller as you want. To fill in a number that you definitely know, use your mouse to left-click on the square and select the number. To mark a possibility (for example, the 2 can either be here or here), right-click on the square and select the number.
The applet running here is from the ActivityWorkshop, and the numbers were generated using the free (GPL'd) software
Sudoku Sensei.
This example is coded as N1-056 which means only level 1 rules are needed to solve it, and it starts with 56
empty squares. Later puzzles will get harder, to give you a challenge once you've solved this one!
