The Back Room
Past the count room, behind the door with no sign. Five games that appear in no brochure, carry worse odds than anything on the floor, and are the only place two pieces of the case are hiding.

What "off the books" actually means
On the main floor, losing costs money. Back here, losing can cost the run. These games sit outside the casino's accounting and outside its protection: no pit boss intervenes, no dispute gets settled, and the outcomes are permanent for the night you are playing.
In exchange, the back room offers three things the floor cannot. Payouts that scale far beyond table limits. Access to people who do not sit at tables. And information — two of the ten hard evidence items in A Deck of Lies only surface through a back-room encounter.
You can finish the night without ever opening that door. You cannot finish it perfectly.
Three Doors
A dealer, three closed doors, a briefcase behind one. You pick a door. The dealer — who knows where the case is — opens one of the other two, always revealing it empty. You may switch or stand. Even money either way.
This is the Monty Hall problem dealt as a casino game, and the correct play is genuinely counter-intuitive enough that most players get it wrong at the table.
Your first pick is right one time in three. That does not change when a door opens, because the dealer was always able to open an empty door regardless of your choice — the reveal adds no information about your door. It concentrates all the remaining probability onto the one unopened door you did not pick.
| Strategy | Wins | Win rate | Expected return at even money |
|---|---|---|---|
| Stand on first pick | 100 | 33.3% | −33% per play |
| Always switch | 200 | 66.7% | +33% per play |
Always switch. Three Doors is the only game in the entire building with a positive expected return for the player, which is precisely why it is back here where the house can watch who plays it correctly. Winning it repeatedly tells the room you are the kind of person who thinks — and that is not always a safe thing to advertise.
Russian Roulette
Six chambers, one live round, cylinder spun before every pull. Each pull you survive doubles the pot; you may stop after any pull and walk with it.
Because the cylinder is respun each time, the pulls are independent: every single pull is exactly 1-in-6. There is no "the odds get worse as you go" and no "I'm due" — there is only how many independent 5/6 gambles you are willing to stack.
| Pulls | Survival chance | Pot multiplier |
|---|---|---|
| 1 | 83.3% | 2x |
| 2 | 69.4% | 4x |
| 3 | 57.9% | 8x |
| 4 | 48.2% | 16x |
| 5 | 40.2% | 32x |
| 6 | 33.5% | 64x |
The multiplier outruns the risk on paper — 33.5% of 64x is an expected 21x — which is exactly the reasoning that gets people killed. Expected value is meaningless when one branch of the tree ends the run. There is no rematch here. Your character does not come back, and neither does anything they were carrying.
Pistol Duel
Ten paces, a coin flip on the count, winner takes the pot. Unlike the revolver, this one is not pure chance:
- Nerve steadies the count and improves your flip.
- Luck nudges the flip directly.
- Charm can end the duel before it starts — the best possible outcome, and the one nobody takes.
You may also send your companion out in your place. If they win, you keep the pot and they remember the favour. If they lose, they are gone for the run, along with your ability to save, the side jobs they were holding, and everything in the backpack they were carrying. Sending a companion to a duel is the most expensive convenience in the game.
Liar's Dice
Five dice each under a cup. Players bid on the total count of a face value across all cups; each bid must raise the previous one. Call "liar," and whoever is wrong loses a die. Last player holding dice wins.
This is the only back-room game that rewards patience over nerve. With two players and ten dice in play, the expected count of any given face is 10 ÷ 6, or about 1.67. A bid of three of a face is already optimistic unless the bidder holds two of them; a bid of five is almost always a bluff or a genuine monster, and telling those apart is the whole game.
Practical reads: count your own dice first and subtract them from the bid — you are only estimating the opponent's five. Bids that jump several steps at once are usually pressure, not strength. And a companion with high Logic will flag obvious bluffs before you have to commit.
Jallikattu
A bull-taming pit adapted for Lucky's back lot. Cling to the hump for fifteen seconds while the bull bucks left, right or holds; match each prompt in time. Miss twice and you are thrown.
The prompts accelerate, so the difficulty is not uniform — the last five seconds contain roughly as many inputs as the first ten. Ride it out and the bookies pay 2x the ante and someone in the crowd hands you a name for the case file, which is frequently worth more than the money. Get gored and the run ends in the dirt.
Should you go back there at all?
A straight cost-benefit read:
| Game | Player edge | Worst case | Verdict |
|---|---|---|---|
| Three Doors | +33% if you switch | Lose the ante | Play it, every time |
| Liar's Dice | Skill-dependent | Lose the pot | Play it if you read people |
| Jallikattu | 2x on a reflex test | Run over | Only for the case name |
| Pistol Duel | Coin flip, stat-adjusted | Run over | Talk your way out |
| Russian Roulette | 1-in-6 per pull | Run over | Never, unless the story demands it |
Note the pattern: the two games that cannot kill you are the two with real player edges. Everything with a body count pays in adrenaline.
Common questions
Do back-room games affect my meters?
Heavily. Winning back here raises mob heat rather than floor suspicion — the house does not mind you winning, but the people who run the room take an interest in anyone who takes money out of it.
Can I lose evidence I have already collected?
Evidence in the ledger is safe. Items in the backpack and unsaved progress are not, and both are tied to your companion.
Is the door always open?
No. Access depends on who you have talked to and how the floor currently feels about you.
