Slotonauts No Deposit Bonus, Free Spins and the 375% Welcome Package
New players at Slotonauts get a welcome package of 375% + 300 FS, up to 3,000€, spread over the first three deposits. The Slotonauts no deposit bonus works differently: such bonuses sit in the No Deposit Bonuses tab of your account and are paid as prizes in the weekly 7-Day Battle. Slotonauts free spins also come every Tuesday with the loyalty levels, from 10 to 50 FS depending on your points. All amounts are in euros, the only currency of the account.
The Sign up form has no promo code field: the welcome bonus is available after sign up, and each of its three parts starts with the Activate button on its card.

The welcome package is three separate deposit bonuses that add up to the 375% + 300 FS headline. The account shows each one with its own minimum deposit and the same wagering and bet rules:
| Deposit | Bonus | Free spins | Minimum deposit | Wagering | Max bet |
|---|---|---|---|---|---|
| 1st | 100% | 100 FS | 20€ | x40 | 2€ |
| 2nd | 125% | 100 FS | 100€ | x40 | 2€ |
| 3rd | 150% | 100 FS | 200€ | x40 | 2€ |
The cap for the whole package is 3,000€, the figure the Sign up popup shows above its "Sign up & claim bonus" button. In the account, each card carries a countdown timer and an Activate button, and the banner "100%+100 FS - 1st welcome bonus" marks the first part. A separate card marked Best offer adds "50 FS on your any 2nd deposit!".
Where the Slotonauts No Deposit Bonus Comes From
A no deposit bonus at Slotonauts is one you receive without paying in for it, and the account keeps them in one place: the OFFERS section has three tabs, OFFERS, CASHBACK and No Deposit Bonuses. The published source is the weekly 7-Day Battle, whose winners are paid in no deposit bonuses or free spins. Loyalty levels add free spins every Tuesday, and the Cosmic Legend level adds Monthly Free Bonuses. Registration itself works differently. The Sign up form promises the welcome bonus, which is tied to deposits, and the published offers include no fixed gift for opening an account alone. Like every Slotonauts bonus, a no deposit bonus follows the general rules: one active bonus at a time, a 2€ maximum bet and a verified phone number.
7-Day Battle: a 300€ Prize Pool Every Week
The Battle runs every week, Monday to Sunday, and ranks players by the sum of their bets in the selected slots. Bets placed with bonus money do not count. The top ten share the pool:
- 1st place: 50€
- 2nd and 3rd place: 25€ each
- 4th to 10th place: 10€ each
Prizes are paid as no deposit bonuses of up to 50€ with 75x wagering, or as free spins in Joker's Fire Bar, and a prize bonus stays valid for 72 hours. Every place in the top ten also earns 1 loyalty point, and the first 25 players get bonuses and loyalty points.
Slotonauts Free Spins Every Tuesday: Five Loyalty Levels
The loyalty programme is called Characters. Points move you up the ladder, a deposit of 50€ qualifies you for level 1, and each level raises the Tuesday free spins:
| Character | Points | Tuesday free spins | Other rewards |
|---|---|---|---|
| Moon Hooper | 10 | 10 FS | +1 loyalty point every Monday, Cashback |
| Star Scout | 25 | 20 FS | +2 loyalty points every Monday, Cashback |
| Astro Explorer | 50 | 30 FS | +3 loyalty points every Monday, Cashback, FS subscription every Wednesday, increased deposit bonuses |
| Galaxy Captain | 150 | 40 FS | +5 loyalty points every Monday, Cashback, FS subscription, Exclusive Bonuses |
| Cosmic Legend | 300 | 50 FS | Monthly Free Bonuses, Cashback, FS subscription, VIP Bonuses |
Moving from Moon Hooper to Cosmic Legend raises the Tuesday spins fivefold, from 10 to 50 FS. Your progress shows on each Character card as "0 / N" points, so you can see how far the next level is.
Up to 50€ for Installing the App
The App page promises "up to 50 € for installing the Slotonauts application". The amount depends on the deposit you make:
- Deposit from 1€: 5€
- Deposit from 51€: 10€
- Deposit from 101€: 15€
- Deposit from 251€: 20€
- Deposit from 501€: 30€
- Deposit from 1,001€: 50€
The deposit has to be made before installing or within 72 hours after, and the bonus is given once. The Cashbox methods for a UK account start at 20€, which already lands in the first tier. The Slotonauts application is an APK file on Android and a Home Screen icon on iPhone, both started from the official App page.
Weekly Lottery and Cashback
The Weekly Lottery has a prize pool of 27,500€ split into 1,000 gifts, and the top gift is 100€ + 5 points. Each draw's details open from the Info button on the PROMOTIONS page. Cashback is part of every loyalty level from Moon Hooper to Cosmic Legend and has its own CASHBACK tab in OFFERS, next to the welcome cards. The login popup sums up the rhythm of these promotions with the line "CATCH THE COOL REWARDS, EVERY HOUR, DAY, WEEK AND MONTH!", under Bonuses, Battle and Lotteries.
x40 Wagering, 2€ Max Bet and What Counts
Wagering is the amount you bet before bonus money turns into a balance you can withdraw. The welcome cards show x40, Battle prizes 75x, and the same rules apply throughout:
- The maximum bet while a bonus is being wagered is 2€; larger bets can be treated as abuse.
- Table games such as Roulette, Sic Bo and Baccarat and video poker do not count toward wagering.
- Space Plinko (Veliplay) counts at a rate of 0.1.
- A single wagering bet must not exceed 20% of the bonus amount.
- Only one bonus can be active at a time.
Your own deposits have a separate rule: each one must be bet three times before a withdrawal, so 10€ needs 30€ of bets, and funds withdrawn without being wagered carry a 20% fee. Once the wagering is done and your documents are uploaded, you can withdraw your balance by the same method you used to deposit.
Activate First, Then Deposit
A bonus starts only from its card, and the order matters, because the rules ask for activation before the deposit:
Confirm your phone
Log in to Slotonauts and confirm your phone number in PROFILE, since bonuses need a verified phone.
Activate the card
Open OFFERS and press Activate on the card you want.
Make the deposit
Go to the Cashbox, choose DEPOSIT and pay at least the minimum the card asks for.
Play eligible games
Play games marked by the "Active Bonus" filter, which shows the titles you can play with a bonus.
The bonus then moves through the statuses IN PROFILE, ACTIVATED, PENDING WAGERING and BONUS WAGERED; a cancelled one shows BONUS CANCELED.
One Account, One Bonus Path
Slotonauts allows one account per device, IP address and phone number across all its domains, and the app bonus is given only once. Deposit only what you planned to spend, even when a wagering target or a countdown is close to the end. Self-exclusion is available through Support. 18+. Gambling can be addictive, play responsibly. Free, confidential support: National Gambling Helpline 0808 8020 133.
What UK Players Ask About Slotonauts Bonuses
Is there a Slotonauts promo code?
No code is needed. The Sign up form has no promo code field, and the welcome package, the app bonus and the Battle prizes are all claimed without one. Bonuses are switched on from their cards, not typed in.
How long do I have to use the welcome bonus?
Each welcome card in OFFERS shows a countdown timer next to its Activate button, so the time left is visible before you pay in. The Battle's prize bonuses have a fixed 72 hours instead.
Why was my bonus not credited after a deposit?
Three rules decide it: the card has to be activated before the deposit, your phone number must be confirmed, and no other bonus may be active at the same time. If all three were met, contact Support with the deposit details.
Do sports bets count toward wagering?
Yes. Bets on Sport count toward the wagering, and at odds of 1.55 or higher they count three times faster.
What happens if my balance runs low during wagering?
When the balance falls to 0.20€, the wagering is annulled. Bonus bets also bring one more withdrawal rule: you need a deposit made within the last 30 days before you can cash out.
