I like that one better. Smaller. More manageable. I don't want to spend 2 hours deciphering the big one.

Took 4.5 min to solve #519. Would have been quicker if I started with a better strategy but it was my first time.

I got #520 in 3m 8s with some practice on the big one.

I thought the bigger one was more fun though, I'll continue with that one now.

Got 3m 32s on #519!

#520 seems much harder tho!

What a great game, just wish the colours were configurable (colour blind)!

519 seems to have at least 3 solutions... feels a little underconstrained!
