+"The game starts with a grid of cells. Some cells contain a mine, others do not. If you click on a cell containing a mine, you " { $strong "lose" } " (it blows up!). If you click on all the cells (without clicking on any mines), you " { $strong "win" } "!"

+"The upper left corner contains a counter of the number of mines left to find. This number will update as you flag or unflag cells."
+$nl
+"The upper right corner contains a timer. This timer will count the number of seconds since beginning to play, maxing out at " { $snippet "999" } " (16 minutes and 39 seconds)."
+$nl
+"Clicking on a cell which doesn't have a mine reveals the number of neighboring cells that contain mines. Use this information (plus good guessing!) to avoid the mines."
+$nl
+"To open a cell, point at the cell with your mouse and click on it. The first cell you click to open is never a mine."
+$nl "Every cell has up to 8 neighbors: the cells adjacent above, below, left, right, and all 4 diagonals. The cells on the sides of the board (and its corners) have fewer neighbors."
+$nl
+"If you open a cell with no neighboring mines all of its neighbors will automatically open. This can sometimes be a large area."
+$nl
+"To flag a cell you think is a mine, point and right-click (or hover with the mouse and press " { $snippet "SPACE" } "). Do this again to mark with a question mark symbol (useful if you are unsure about a cell). Do this again to return the cell to blank."
+$nl
+"If you flag a mine incorrectly, you will need to correct that mistake before you can win."
+$nl
+"You do not have to flag all the mines to win, you only need to open all the cells that do not contain mines."
+$nl
+"Click the yellow smiley face (or the desired difficulty) to start a new game."
