A zero-play day happens when you're staying at a casino — occupying a room on your loyalty account — but record no significant play. This single day can cut your Average Daily Theoretical (ADT) by 30-50% and reduce your future mailer offers for months. Understanding how to avoid it is one of the most important comp strategies in video poker.
How ADT Averaging Works
Casinos calculate your comp value using your ADT — the average theoretical loss per day across your entire stay.
Scenario A: Two-night stay, play both days
- Day 1: $5,000 coin-in → $100 theo
- Day 2: $5,000 coin-in → $100 theo
- ADT: $200 / 2 days = $100/day
- Result: Strong mailer offers for your next trip
Scenario B: Three-night stay, play only two days
- Day 1: $5,000 coin-in → $100 theo
- Day 2: $5,000 coin-in → $100 theo
- Day 3: $0 coin-in → $0 theo
- ADT: $200 / 3 days = $67/day
- Result: Mediocre mailer offers — 33% weaker than Scenario A despite identical play
Same total play, same total cost, dramatically different comp results. The third day diluted your value.
What Triggers a "Gaming Day"
The casino's system records a gaming day when:
- You check into a room on your loyalty account
- You swipe your card at a kiosk (even for a "daily prize")
- You use loyalty points for any transaction (coffee, parking, etc.)
- You sit at a machine with your card inserted, even briefly
Any of these actions creates a data point. If that data point has zero or minimal play attached, it tanks your average.
Three Rules to Protect Your ADT
Rule 1: Don't Swipe If You Don't Play
If you're visiting a casino for dinner or a show but not planning a full session, leave your player's card in your wallet. Swiping at a kiosk for a $5 prize while recording a near-zero play day costs you far more in future mailer value.
Rule 2: Match Your Stay to Your Play
If you have the bankroll for three days of heavy play, book three nights. If you only have the bankroll for two days, book two nights — even if you want to stay longer.
The workaround: Stay your first two nights at Caesars (playing heavily both days). Move to a non-gaming hotel or a different operator for night three. Both properties see 100% full-play days.
Rule 3: Check Out When You're Done Playing
If your flight leaves on Day 4 but you finished playing on Day 3, check out on Day 3. Spend the last night at a budget hotel near the airport. The cost of a $60 airport hotel is far less than the $200-$500 in future mailer value you'd lose from recording a zero-play day.
When a Zero Day Is Acceptable
There are rare situations where recording a zero is fine:
You're leaving a program permanently. If you've decided to switch from Caesars to Boyd and won't return to Caesars properties, using your remaining Caesars room offers without playing doesn't matter.
The property's play level doesn't matter to you. If you received a free room at a property you'll never visit again (e.g., from a tier match promotion), enjoying the room with zero play is essentially free value.
In all other cases — any property where you want future offers — protect your ADT by avoiding zero-play days.
Recovering from a Zero Day
If you accidentally recorded a zero-play day:
- You can't retroactively fix it in the system
- The best recovery is to schedule a high-volume session within the same 90-day mailer window
- A single strong day ($10,000+ coin-in) can partially offset a zero in the rolling average
- Talk to your host — they may have discretion to adjust offers if you explain the situation
Prevention is always better than recovery. The mailer algorithms are automated, and hosts have limited ability to override them.
