Anyone know of a good website that lets you play Lights Out?
I found some websites that offer playing for free, but they aren't the sort of sites I'd recommend to others, because they have offensive ad-content or require downloads or just seem sketchy in one way or another.
I'd especially like to know of a site that lets you play a mod 3 version, where clicking on a cell increments it and its neighbors by 1 mod 3. (The usual version is mod 2.)
Thanks,
