In Chaos, you need to collect sets of 3 identical Spectrum cards and place them on the table. Or collect the set of 3 Order cards and keep it in your hand until the end of the round.
Avoid the 4th Spectrum card that matches a set you have placed on the table or the 4th Order card if you have the other 3. Also avoid holding a Chaos card at the end of the round.
On your turn you can seek a card trade a card or declare a battle. You can't hold Order cards while holding a Chaos card. If you discard a Chaos card all hands are rotated among players until the discarding player calls Stop.
