The idea for the ColossusKings comes from the mathematician Ingo Althöfer.
I extended some of his variants to get the MonsterKings.

It is almost normal chess, but there are no queens and the kings are colossuses with some features of a monster. The kings are so large that they need 2x2 squares to stand on.

A team has lost when any quarter of its king has been checkmated.

The 'Colossus Kings' are only hugh and very weak, but as 'Monster Kings' they have more power because of the feature to move two fields in any direction.
Observe that as a speciality a king can also capture own pieces.
He is a monster...

The package contains two ZRFs:
'ColossusKings.zrf' (4 variants)
and 'MonsterKings.zrf' (2 variants)
