Primary type =
Same primary type
The Primary type = connection is one of the types & combat rules in the daily PokéWired Pokémon puzzle. Two Pokémon are linked by it when this holds: Same primary type.
It's not directional: it works both ways, so it doesn't matter which Pokémon goes on the left and which on the right. You'll meet it in Normal puzzles, and it can also show up in the Unlimited and Chain modes.
Type connections are the backbone of most chains — they ask about a Pokémon's typing, its weaknesses and resistances, and how one type fares against another in battle.
