I have created a game called Lights Out (a.k.a. Lights Out or Lights On), which is available at my TI-BASIC programmer's group website, calcodes.wikidot.com. Just click on Programs, then click on Lights Out and go from there. Right now there is a 3x3 grid and the standard 5x5 grid version available.
Looks like a fun game, although it could use some optimization. When did you decide to start your CalCodes group? What are your plans for it?
I started CalCodes a few days ago. I plan on having CalCodes getting well-known, but right now, I just want to get it off the ground.
If you look at the bio page at calcodes.wikidot.com, I will never be able to force myself to leave out ending " and ). Having learned another programming language first, I will not be able to do that particular optimization. There is a lot more I can do, and I will probably only refine the 5x5 grid version with level support.
