It is a large-group game that pits two teams against each other: the Red Team and the Blue Team. The game is played in two rooms (or separate areas) with players divided into these two teams.
The objective of "Two Rooms and a Boom" varies depending on the game mode and the number of players, but the core mechanics involve negotiation, bluffing, and deduction. The game components include role cards representing different characters with unique abilities, a timer, and a deck of cards representing hostages.
To start the game, players are randomly assigned role cards representing their allegiance and abilities. Each round consists of several phases, including the "Election Phase," where players vote on who will be the leader of each team, and the "Trading Phase," where players can negotiate and exchange role cards with each other.
The game ramps up as players try to figure out who is on their team, form alliances, and manipulate the other team's plans. The tension builds as the timer counts down, and players must make crucial decisions about who to trust and which hostages to exchange.
The game culminates in the "Boom Phase," where the two rooms converge, and the leader of each team chooses hostages to exchange between the rooms. Depending on the outcome of these hostage exchanges, the teams may win, lose, or trigger sudden-death conditions.

It accommodates large groups of players and offers a dynamic and engaging experience that encourages communication and teamwork.
