Here is my entry in the smallest-game contest.  I wrote it several years
ago as a tiny TSR (383 bytes) and adapted it for the contest by removing
the TSR code.  This brought it down to 217 bytes.  I could squeeze a
few more bytes if I used 386-specific instructions but it is already
well under the 256-byte limit.

to start at 100h.

Merlin is played on a three by three board and the object of the game
is simple; all you need to do is clear the board.  The numeric keypad
is used to toggle the squares.  Here is the layout:

					+---+---+---+
					| 7 | 8 | 9 |
					+---+---+---+
					| 4 | 5 | 6 |
					+---+---+---+
					| 1 | 2 | 3 |
					+---+---+---+

Pressing a key will toggle certain squares on or off.  The idea is to
clear the whole board.  Pressing the 1 key will toggle these squares:

					+---+---+---+
					|   |   |   |
					+---+---+---+
					| X | X |   |
					+---+---+---+
					| X | X |   |
					+---+---+---+

Likewise, any corner key toggles the four squares in the corner.  Edge
keys (2,4,6,8) toggle the squares on the edge.  Here is an example for 2.

					+---+---+---+
					|   |   |   |
					+---+---+---+
					|   |   |   |
					+---+---+---+
					| X | X | X |
					+---+---+---+

The 5 key toggles the central squares:

					+---+---+---+
					|   | X |   |
					+---+---+---+
					| X | X | X |
					+---+---+---+
					|   | X |   |
					+---+---+---+

That's all there is to it.  You can scramble the board at any time by
pressing ENTER.  Press ESCAPE to exit Merlin.  Don't forget to set
NUMLOCK if you don't have a dedicated keypad.
