I had the idea to make an electronic version of the board game Battleships for my neice and nephew.

I'm doing it without a microcontroller as my computer is currently in storage, and I like to make things when I can.

Note: circuit I have posted will be repeated 50 times to make up the board.

IMG1 shows the circuit before the game begins.

IMG2 shows S1 closed which turns on L1. This indicates that Player1 has part of a ship on this 'tile'.

IMG3 shows S2 is closed. Because S1 is also closed, this turns on L3. This indicates that Player2 has HIT Player1's ship.

IMG4 shows S2 is closed, but S1 is open which turns on L2. This indicates that Player2 has MISSED Player1's ships.

As you can see, to get the MISSED part of the circuit to work I've used a PNP to find when S1 is open, but this results in a small current flowing through L1.

Being that it's so small, I don't believe it will actually illuminate L1, but would it be a problem?

Additionally, could any other issues such as excess power draw arise when there are 50 sets of this circuit? At the very most (during a game, not testing) this particular state(see IMG4) could happen 28 times.

Thanks in advance.

EDIT 1: I forgot to mention that the switches are latching push button switches.
