Portals

Portals are a TFT mechanic that alters the rules of an entire lobby before the match begins. At the start, players vote on options and one portal is chosen, applying its effect to everyone — for example, granting bonus starting items, extra gold, free champions, or changing how carousels work.

Because a portal can dramatically shift the best opening, reading the active portal and adjusting your early plan is a real skill. Portals were introduced as a headline set mechanic to add variety between games, so that no two lobbies start exactly the same way.
