Otherwise, a number appears at the firing point +and the location where the laser emerges (this number is unique to +that shot). + +You can place guesses as to the location of the balls, based on the +entry and exit patterns of the lasers; once you have placed enough +balls a button appears enabling you to have your guesses checked. + +Here is a diagram showing how the positions of balls can create each +of the laser behaviours shown above: + +\c 1RHR---- +\c |..O.O...| +\c 2........3 +\c |........| +\c |........| +\c 3........| +\c |......O.| +\c H........| +\c |.....O..| +\c 12-RH--- + +As shown, it is possible for a ball to receive multiple reflections +before re-emerging (see turn 3). Similarly, a ball may be reflected +(possibly more than once) before receiving a hit (the \q{H} on the +left side of the example). + +Note that any layout with more that 4 balls may have a non-unique +solution. The following diagram illustrates this; if you know the +board contains 5 balls, it is impossible to determine where the fifth +ball is (possible positions marked with an x): + +\c -------- +\c |........| +\c |........| +\c |..O..O..| +\c |...xx...| +\c |...xx...| +\c |..O..O..| +\c |........| +\c |........| +\c -------- + +For this reason when you have your guesses checked the game will +check that your solution \e{produces the same results} as the +computer's, rather than that your solution is identical to the +computer's.
