Diamond Jo Worth Casino is a Boyd Gaming property near Northwood, Iowa, just off Interstate 35 near the Minnesota border. Its main appeal is convenience: approximately 801 slots, live tables, a sportsbook, several restaurants, and an attached 102-room hotel make it practical for a highway stop or an overnight outing. It best suits regional visitors who want gambling, dinner, and a room in one place. The trade-off is a car-dependent setting rather than walkable nightlife or a sprawling vacation resort.

What kind of casino is Diamond Jo Worth?
Think regional casino with enough dining and lodging to turn an afternoon stop into a complete evening. The operator’s property fact sheet lists slots, tables, sports betting, an attached hotel, restaurants, and an event center. That combination is useful for companions who do not all want to spend the evening gambling.
I like the interstate-area setting for an uncomplicated drive-in visit. I like it less for someone who wants to park once and wander between independent restaurants and bars all weekend. This is not a downtown Northwood entertainment district.
It is also not Diamond Jo Casino in Dubuque. Make sure your room reservation, dinner booking, concert ticket, and navigation destination identify Northwood or Worth County. For broader trip planning, see our Iowa casinos guide.
Casino floor and games
Approximately 801 slots and 19 table games make this more than a token gambling stop. Machines dominate the published inventory, while live tables and the sportsbook provide alternatives. The important distinction is inventory versus availability: a listed table is not necessarily operating throughout the day.
Slots and video poker
The machine selection makes Diamond Jo Worth a reasonable option for a slot-focused outing. Check specific titles, denominations, and video-poker pay tables on arrival rather than building a trip around a particular machine.
My usual advice applies: read the total wager, not just the denomination on the cabinet. A penny game need not mean a penny spin. If you find a video-poker game you like, examine its pay table before playing.
A large selection does not establish better odds. Neither jackpot photographs nor accounts of winning or losing sessions tell you a casino-wide return percentage.
Table games
The operator lists 19 table games. If a particular game is the reason for your drive, call about the current lineup, operating hours, minimum wagers, and rules.
I would not plan a budget around an old low-minimum advertisement. The minimum posted when you sit down is the one that matters, and optional side bets add to your wager rather than replacing it.
Poker room
Diamond Jo Worth has no dedicated player-versus-player poker room. Video poker and poker-themed games played against the house are different from a cash-game room.
Sportsbook
Diamond Jo Worth has an on-property sportsbook, and the operator lists 20 betting kiosks. Sports betting can be the reason for a stop without making slots or tables the centerpiece of the visit.
Check staffed-counter hours separately from casino hours, especially if you need help placing a wager or redeeming a ticket. Read the redemption instructions before leaving, and keep physical tickets secure. Restaurant televisions are for watching games, not a substitute for betting-counter service.
Hotel: rooms, amenities, and overnight value
The attached 102-room hotel is one of the property’s most useful features. Staying overnight makes particular sense for a show, a late dinner, or a visit that would otherwise end with a long drive home. It also lets traveling companions finish their evenings at different times.
The hotel guest directory lists check-in at 3:00 p.m. and check-out at 11:00 a.m., plus complimentary breakfast, free hotel Wi-Fi, a fitness center, a business center, guest laundry, and meeting rooms.
Breakfast hours are 6:00 a.m. to 9:30 a.m. on weekdays and 7:00 a.m. to 10:30 a.m. on weekends and holidays. That early weekday start is handy for an interstate departure; after a late show, remember that breakfast still has a closing time.
I would judge the hotel primarily on convenience and the final booking price, not treat the word casino as a promise of a resort vacation. Check the room category, cancellation deadline, taxes, and additional charges before paying.
Extra hotel charges to budget for
- Cribs: Free for guests, according to the directory.
- Rollaways: $10 per night; contact the front desk about availability.
- Dogs: Permitted in specified rooms, with a nonrefundable $50 fee plus tax.
- Smoking in a nonsmoking room: A $200 recovery fee.
Using those published charges, a dog and one night of rollaway use add $60 before applicable taxes and the room rate. For an illustrative three-night stay, the rollaway alone adds $30 before any applicable tax. These are calculations from listed charges, not room-package quotes. Confirm current terms and whether a designated dog-friendly room can accommodate a rollaway.
Gamboool original analysis
We assembled the comparison below from published information and our calculations. These are selected examples, rather than measured gambling sessions or a representative survey.
| Detail | Published information |
|---|---|
| Attached hotel: Published room inventory | The operator’s June 2025 fact sheet lists an attached hotel with 102 rooms. |
| Hotel: Check-in and check-out policy | The published guest directory lists check-in at 3 p.m. and check-out at 11 a.m.; guests needing other arrangements should call the front desk. |
| Hotel breakfast: Included breakfast and weekday versus weekend hours | Breakfast is complimentary. Weekday service runs from 6 a.m. to 9:30 a.m.; weekend and holiday service runs from 7 a.m. to 10:30 a.m. |
| Hotel: Wi-Fi price and coverage | The guest directory includes free Wi-Fi throughout the hotel; this passage does not establish casino-floor coverage. |
| Hotel extra beds: Crib versus rollaway pricing | Cribs are free for guests, while rollaways cost $10.00 per night and require contacting the front desk. |
| Hotel dog policy: Room restriction and nonrefundable charge | Dogs are permitted only in specified rooms, with a nonrefundable $50.00 fee plus tax. The passage does not specify weight limits, dog limits, or the fee’s recurrence. |
| Hotel nonsmoking rooms: Smoking recovery charge | Smoking in a nonsmoking room incurs a $200.00 room recovery fee. This hotel-room policy does not establish the casino floor’s smoking policy. |
| Sportsbook: Published betting kiosk inventory | The operator’s June 2025 fact sheet lists a sportsbook and 20 betting kiosks; it does not give counter or kiosk operating hours. |
| Dining: 35 Brew Street food and viewing setup | The operator describes 35 Brew Street as a pub-style dining option with 18 TVs, draft beer, and cocktails. |
| Dining: Mixx food and viewing setup | Mixx offers cocktails, mocktails, casual quick eats, and 14 high-definition screens, providing another published game-viewing option alongside 35 Brew Street. |
| Dining: Woodfire Grille dining format | Woodfire Grille is the published fine-dining option, with salmon, beef, pasta, wine, and desserts rather than the pub-style format described for 35 Brew Street. |
| Calculation | Result | Takeaway |
|---|---|---|
| Rollaway cost for an illustrative three-night stay | 30 US dollars, excluding any applicable tax | The rollaway charge accumulates nightly, so include the full stay when comparing room arrangements. Confirm availability with the front desk. |
| Published dog fee plus one night of rollaway use | $60.00 in extras, excluding the room rate and applicable taxes | A dog and a rollaway add separate charges to the room bill. Confirm that a designated dog-friendly room can accommodate the requested rollaway before booking. |

Method: Published inputs collected 2026-10-16. Illustrative assumptions are labeled, and the full calculation inputs remain in the saved research record. These examples support planning; they do not predict a particular session.
My takeaway: compare the total cost of the room arrangement you actually need. A lower advertised nightly rate is not automatically the cheaper booking once a dog or an extra bed enters the picture. The hotel dog policy also does not establish pet access to the casino floor.
Restaurants and bars
The dining lineup covers a sit-down dinner, pub food, drinks, and quicker meals. Here is how I would sort the published options:
| Venue | Published offering | Best fit |
|---|---|---|
| Woodfire Grille | Beef, salmon, pasta, wine, and desserts in a fine-dining setting | A dinner-centered evening or meal before a show |
| 35 Brew Street Bar & Grill | Pub-style food, draft beer, cocktails, and televisions | A casual meal while following a game |
| Mixx Bar & Lounge | Cocktails, mocktails, casual quick eats, and screens | Drinks and lighter food |
| The Burger Joint | Burgers, fries, hot dogs, and shakes | A straightforward meal break |
| Subway | Sandwiches and salads | A quick alternative to sit-down dining |
These recommendations compare dining formats, not meals I have personally eaten. For Woodfire Grille, I would check reservation availability and leave a comfortable buffer before a performance. Check serving hours for the quicker options, too, rather than assuming they stay open as late as the casino.
Both 35 Brew Street and Mixx have a game-viewing role in their published descriptions. Choose between them for the food, seating, and atmosphere you want, not on the assumption that dining and sportsbook services operate together.
Entertainment and amenities
The event center hosts scheduled live entertainment and comedy. A specific show can make a dinner-and-overnight visit more appealing, but entertainment is calendar-dependent, not something to expect every evening.
Check the event’s door time, seating arrangement, admission rules, and ticket conditions. If staying overnight is essential, secure a room before committing to a nonrefundable ticket.
For nongamblers, I would build the outing around a particular meal or event. The hotel fitness center and practical amenities help with an overnight stay, but they are not a destination’s worth of daytime activities.
Directions and practical visit information
Navigate to 777 Diamond Jo Lane, Northwood, Iowa. The I-35 location near the Minnesota border is the main logistical advantage for drivers from northern Iowa and southern Minnesota.
Plan this as a car-based outing. Arrange accessible parking needs, event drop-offs, and transportation after drinking before arrival. I would not make a late-night return depend on finding an on-demand ride after the fact. In winter, check road conditions and allow extra time.
- Age and identification: You must be 21 or older to gamble. Bring valid government-issued identification.
- Hours: Check casino, table-game, restaurant, and sportsbook schedules separately.
- Smoking: If smoke exposure is a deciding factor, ask about the current casino-floor policy and routes to dining and entertainment. A nonsmoking hotel-room policy does not describe the casino floor.
- Parking and room costs: Ask about applicable charges rather than assuming they are included.
- Rewards: Ask the players club which benefits and offers apply before playing. Do not extend a gambling session merely to chase a reward.
Who Diamond Jo Worth suits
Diamond Jo Worth suits I-35 travelers and regional visitors who want slots, sports betting, dinner, and an attached hotel without organizing a city getaway. I think its strongest overnight argument is practical: pair a scheduled show or sit-down meal with gambling, stay close, and have breakfast included. The trade-off is a car-dependent setting and fewer reasons to spend a full day away from the gaming floor. Choose another destination if walkable nightlife or extensive resort recreation is the main point of your trip.
