Granny's Maze

Numbers are scattered across the page like a game of dots. Starting at 1, you're told the next number to reach — say, "from 1, go to 33." Drag a single continuous line from your current spot to that number, staying on the page. The only rule: your line can never cross a wall, a number, or a line you've already drawn. Cross one, and you're stuck — game over. Clear the whole page and you win.
