How to play
Foundation
Hidden in the grid are keyslots with shape and value matching the prisms in your inventory.
By firing lasers into the grid you can decode where these keyslots must be hidden.
The path of lasers
Select a row or column from the grid border to fire a laser from that position. You will
be shown where the laser starts and where it ends up. In this case it starts at 3 and ends
up at C (thus 3-C). For this path to happen, the laser must have bounced at least once on
hidden keyslots.

The sum of lasers
The number below the path is the sum that the laser tallied while traversing the
grid. Each collision with a prism adds that prism's number to the
total sum. In this case, the sum is +5 because 2+1+2=5.
With information about sum and path, you can figure out where prisms
must be placed on the grid.

Lock in your sequence when you have finished decoding the grid. If you are wrong more than
once, the game is over.
