Behind The Scenes

What is “sparks of hope”?

What do you mean by all belong on?

Their similarities.

Never played SoH, but it does seem fun.

No. It's pretty obvious.

But I'll take that, they all use knights quite majorly (is thatt a word)

yes.

Yeah. I was going to say that they all used a 14x14 board.

Not to take credit. Jack beat me.

That was the exact answer I wanted, so you both get points.

I made a set 2 on the forum itself, do that i guess

Does it count if I don't know the variants and have to look them up to find similarities?

yeah!

Crazyhouse

Correct.

Made a set 3.

Their all variants with custom pieces

Something that only them share.

About 90% of variants have custom pieces.

Ambush does not use Knights.

That was comments for set 1. We are discussing set 3.
