Hello, I'm back.
This is a game exactly like Minesweeper.
Press the arrow keys to move your selector thingy.
Press Clear when you think you have won.
Press Enter to chose a space.

What the community thinks:
For the first command, instead of that incredibly long matrix enter can you try this: ?
:
:{16, 16 > dim([A]
…that makes it so much easier…
This will do it as well, but is more reliable, because yours will not reset the Matrix to 0s if [A] had some values in before.
Wake me, when you need me.
it keeps coming up with a sythax on the first command. any help?(ti84+)
Make sure you are selecting [2ND][MATRX][A], not actually typing out [A].
Did I miss something? I'm unable to use the down arrow
(begginer here) where do I find the If not function
in the program editor, hit PRGM, then press enter to insert the If function. After that, hit [2ND] [MATH], scroll over to LOGIC, and select not(. hope this helps :)
Invalid dim?
Where are you getting the error?
