Play Sudoku

This is a simple sudoku game made using HTML5 Canvas.

This game uses a free-to-use api that can be found here thanks to "bertoort" on GitHub.  I use the API for getting new boards, and checking for correct values.

Instructions

• Rules are normal Sudoku rules. You must place numbers on the board such that exactly 1 of each number can be found in each column, row, and 3x3 box. If you've never played, click here for more in-depth rules.
• Click on the board to start filling in the blanks. Alternatively, use the WASD or arrow keys to move around. Clicking a number button, or typing on the keyboard will fill in a number.

The toolbar buttons from left to right are...

1. Pen tool - use when you a number has to go there
2. Pencil tool - use when a number could go there
3. Eraser - erase all numbers in a cell; works on pen as well as pencil
4. New Board - opens prompt to start new game
5. Check - checks all penned in numbers to see if they are correct or not.
