The 30-Second Host Script
💡 Host Takeaway & Quick Tip"Welcome to Two Rooms and a Boom! You belong secretly to either the Red Team or the Blue Team. The Blue Team wins if the President survives, but the Red Team wins if the Bomber ends the final round in the exact same room as the President. You will talk, whisper, and choose whether to reveal your card color or full card to earn trust. At the end of each round, your elected room leaders trade hostages across the hallway. You have three rounds to sort out the truth: three minutes, two minutes, and one minute. Pick your leaders now, and round one starts in three, two, one, go!"
How to Play: Step-by-Step Rules
- Elect a Room Leader: Players in each room pick a leader within the first 30 seconds by pointing, volunteering, or holding an instant voice vote.
- Mingle and Gather Intel: Question players across your room to identify teammates. You may agree to show only the color corner of your card (color share) or reveal your full card (full share), but all reveals must be mutual and voluntary.
- Nominate Hostages: When the host calls a 30-second warning, each leader selects hostages to swap (3 hostages for Round 1, 2 for Round 2, and 1 for Round 3 in a 15-player game; 1 hostage per round for 6 to 10 players).
- Execute the Swap: When the round timer expires, hostages from both rooms cross the hallway, swap places, and enter the opposite room before the doors shut.
- Run the Next Rounds: Start Round 2 (2 minutes) and Round 3 (1 minute) immediately, allowing rooms to depose their leaders or select new hostages each time.
- Reveal and Detonate: When Round 3 ends, call everyone into the hallway and have all players reveal their cards simultaneously.
How to Win and Break a Tie
The Red Team wins if the Bomber and President end Round 3 inside the same room. The Blue Team wins if the President and Bomber finish in separate rooms. If an odd player count includes the Gambler, that individual wins independently by correctly guessing the winning team before cards flip. If a room ties during a leader election as time expires, the host runs a fast 10-second coin toss to decide the leader on the spot.
Variations for Every Group
- Kids Version (Keep It Simple): Strip out all advanced roles and play strictly with the President, the Bomber, and standard Blue and Red team cards so kids focus on basic bluffing.
- Large-Group Version (15+ Players with 5 Rounds): Run 5 total rounds lasting 5, 4, 3, 2, and 1 minutes each, scaling down the hostage count from 3 hostages in early rounds to 1 in the final round.
- Advanced Adult Roles: Introduce grey neutral roles like the Spy (shows blue color but counts as red) or the Rival to create shifting alliances and conflicting goals.
- Budget DIY Swap: Write "Blue - President", "Red - Bomber", and standard "Blue" or "Red" text onto index cards using colored markers instead of buying a pre-printed game box.
Host Tips and Common Mistakes
- Supply Warning: Verify the card count twice before dealing; an uneven split of basic Red and Blue cards unbalances the game instantly.
- Common Pitfall: New players often stay quiet and refuse to share cards. Fix this by announcing that silent rooms lose control of the hostage vote to active players.
- Safety Note: Keep the pathway between rooms completely clear of rugs, cords, and furniture so running hostages avoid trip hazards.
- Host Pro-Tip: Ring a loud kitchen bell or blow a whistle in the hallway so players in both rooms clearly hear the 30-second warning and round transitions through closed doors.
