Room Unlock Order

Each main room has a one-level bribe upgrade that pays off the bodyguard and unlocks the next room. In the first run each bribe starts at 1,000,000 of that room’s currency. In New Game+, bodyguard bribes use 1,000,000 x 10^NG+.

Step	Current Room	Bribe	Bodyguard	Unlocks
1	Darts	Million Nugget Bribe	Verminious the Giant Rat	Lotto
2	Lotto	Million Dollar Bribe	Gorgon the Bullfrog	Pachi
3	Pachi	Million Ticket Bribe	Rimmington the Ram King	Sushi
4	Sushi	Million Ribbon Bribe	Hivemind the Conglomerate	Gacha
5	Gacha	Million Stuffing Bribe	Executor the Doomduck	Sixth Room

Do not wait for every upgrade in a room to be maxed before moving on. New rooms add permanent or passive systems that make older rooms faster.
