The blue circle goes to things made of wood, the red to double consonants - but what could yellow be?

Have the others figured out all three rules that determine which card goes into which round? It's not easy: the catapult, the armchair and the pencil are in blue, as well as the acorn - but it's also in red, next to the mermaid and the scissors! The selection in yellow is also quite mixed: mermaid, lifeguard, smoker... We have it! After all, they all end in the same letter!

State of Matter is a fun and exciting party game in which players have to guess the three rules that determine the placement of cards in three partially overlapping rings. All objects in the red circle are office, but only the calculator is made of plastic. The dog and the elephant are also animals - should the dragon be placed next to them, or only existing animals are included in that circle?
If a card is placed in the wrong place, the player must draw another card - the player who runs out of cards the fastest wins the game!

Can you guess what the three conditions are? Be the first to get rid of your cards!
