Gemini Monsters (known as Dual Monsters in the OCG) are a type of Effect Monster. They have effects, but these effects must be "unlocked" by performing an additional Normal Summon on them while they are face-up on the field (known in the OCG as a Second Summon). Until then, they are treated as Normal Monsters.

Correction: They are treated as Normal Monsters on the field (until they are Gemini Summoned, which is a non-chainable normal summon) and in the graveyard. Everywhere else, they are treated as effect monsters, but don't get their effects.
