+Black Box
+<p>
+Determine where the hidden balls are in the box, by observing the
+behaviour of light beams fired into the box from the sides.
+<p>
+Click in a square around the edge of the box to send a beam into the
+box. Possible results are 'H' (the beam hit a ball dead-on and
+stopped), 'R' (the beam was either reflected back the way it came or
+there was a ball just to one side of its entry point) or a number
+appearing in two squares (indicating that the beam entered one of
+those squares and emerged from the other).
+<p>
+Click in the middle of the box to place your guessed ball positions.
+When you have placed enough, a green button will appear in the top
+left; click that to indicate that you think you have the answer.
+You can also right-click to mark squares as definitely known.

+Bridges
+<p>
+Draw horizontal or vertical bridges to link up all the islands.
+Bridges may be single or double; they may not cross; the islands
+must all end up connected to each other; the number in each island
+must match the number of bridges that end at that island (counting
+double bridges as two). Note that loops of bridges are permitted.
+<p>
+Click on an island and drag left, right, up or down to draw a bridge
+to the next island in that direction. Do the same again to create a
+double bridge, and again to remove the bridge if you change your
+mind. Click on an island without dragging to mark the island as
+completed once you think you have placed all its bridges.

+Cube
+<p>
+Roll the cube around the grid, picking up the blue squares on its
+faces. Try to get all the blue squares on to the object at the same
+time, in as few moves as possible.
+<p>
+Use the arrow keys to roll the cube, or click the mouse where you
+want it to roll towards. After every roll, the grid square and cube
+face that you brought into contact swap their colours, so that a
+non-blue cube face can pick up a blue square, but a blue face rolled
+on to a non-blue square puts it down again.
+<p>
+When you have mastered the cube, use the Type menu to select other

+for a
+<a href="http://en.wikipedia.org/wiki/Group_(mathematics)">group</a>.
+<p>
+If you don't already know what a group is, I don't really recommend
+trying to play this game. But if you want to try anyway, the above is
+equivalent to saying that the following conditions must be satisfied:
+<ul>
+<li>
+<strong>Latin square</strong>. Every row and column must contain
+exactly one of each letter.
+<li>
+<strong>Identity</strong>. There must be some letter <i>e</i> such
+that, for all <i>a</i>, the letter in row <i>e</i> column <i>a</i> and
+the one in row <i>a</i> column <i>e</i> are both <i>a</i>. In the
+default mode, this letter is always <i>e</i> and its row and column
+are filled in for you; by reconfiguring the game using the Type menu,
+you can select a mode in which you have to work out which letter is
+the identity.
+<li>
+<strong>Inverses</strong>. For every letter <i>a</i>, there must be
+some letter <i>b</i> (which may sometimes be the same letter
+as <i>a</i>) such that the letters in row <i>a</i> column <i>b</i> and
+in row <i>b</i> column <i>a</i> are both the identity letter (as
+defined above).
+<li>
+<strong>Associativity</strong>. For every combination of
+letters <i>a</i>, <i>b</i>, and <i>c</i>, denote the letter in
+row <i>a</i> column <i>b</i> by <i>d</i>, and the one in row <i>b</i>
+column <i>c</i> by <i>e</i>. Then the letters in row <i>d</i>
+column <i>c</i> and in row <i>a</i> column <i>e</i> must be the same.
+</ul>

+To place a letter, click in a square to select it, then type the
+letter on the keyboard. To erase a letter, click to select a square
+and then press Backspace.
+<p>
+Right-click in a square and then type a letter to add or remove the
+number as a pencil mark, indicating letters that you think
+<em>might</em> go in that square.
+<p>
+You can rearrange the order of elements in the rows and columns by
+dragging the column or row headings back and forth. (The rows and
+columns will stay in sync with each other.) Also,
+left-clicking <em>between</em> two row or column headings will add or
+remove a thick line between those two rows and the corresponding pair
+of columns (which is useful if you're considering a subgroup and its
+cosets).
