December 2025 Casino Promotions
December brings holiday tunes and freezing weather, that much we know. For online casinos, however, it’s also the peak of their promotional season. Some of these offers arrive with festive packaging, others are simply ongoing bonuses that happen to overlap with the holidays. Either way, there’s a lot going on.
In this article, we’ll give you a breakdown of all the current promotions at online casinos this cold-ish December. A few are December-specific. Others are evergreen. All are available right now.
Winz Casino Promotions
Christmas Calendar
As its take on the Christmas theme, Winz introduced their own version of the advent calendar, only here it’s called the Holiday Calendar. However, just like an advent one, the Winz Holiday Calendar is essentially a rotating set of daily bonuses available until 26 December.
Each day opens at 00:00 UTC and includes its own offer, terms and countdown timer. Once the timer runs out, the offer disappears.
Here’s some basics you should know:
- Calendar runs until 26 December at 23:59 UTC
- One new offer released per day
- Offers must be claimed and used before they expire
- Each one of these bonuses comes with its own conditions
- Rewards are tied to the account holder and non-transferable
Drops Frenzy Fest
BGaming’s seasonal Drops Frenzy Fest is currently active on Winz, running through November into early December. The format is simple: play eligible slots and wait for random prize drops. No opt-in required, no wagering on rewards.
- Prize Pool: €30,000
- Type: Random cash drops
- Games: Selected BGaming titles
- Entry: Automatic upon play
CasinoDays Promotions
CasinoDays is combining seasonal prize drops with regular cashback and a long-running slot tournament.
Daily Cashback

Jackpot Splash
A year-long prize drop campaign focused on Games Global progressives.
| Duration | Prize Pool | Top Daily Prize | Min Stake | Wagering |
|---|---|---|---|---|

At some point, you’ll realize that surprise wins are awarded randomly. These daily drops continue through to the end of December.
Spinoleague Tournament
CasinoDays also participates in Spinomenal’s Spinoleague, a multi-round slot tournament with €12 million in total prizes.
- Entry via in-game pop-up
- Score points using Win/Bet ratio
- Prizes are paid within 72 hours, no wagering
- Runs in multiple rounds, ending with a “Super Round”
- Minimum bet per spin: €0.20
There’s nothing particularly festive about it, but then again, €12 million doesn’t need a lot of tinsel.
Spinbetter Promotions
Spinbetter has a little bit of everything: birthday perks, NFT-fueled tournaments and themed prize drops.

Aviatrix Tournament
Not a bonus but a tournament that combines crypto-mechanics with standard tournament logic.
| Dates | Format | Prize Pool |
|---|---|---|

- Earn points by betting with NFT planes
- Two stages: qualify with a bet, then claim a reward

Sweet Holiday Chase
Another seasonal promotion comes from Bitkingz, in the form of their Sweet Holiday Chase, a Pragmatic Play network promotion that’s been running weekly from November 19 and will continue until January 14.
