The spinboss bonus is a four-deposit welcome package worth 400% up to £15,000 plus 400 free spins, with 40x wagering and a £20 minimum deposit. Below you will find how the offer splits across deposits, how the free spins work and what to check before you opt in.

Welcome Bonus Overview
New players get a spinboss casino welcome bonus spread over the first four deposits rather than a single lump sum. Added together, the package comes to 400% up to £15,000 and 400 free spins. The minimum deposit to qualify is £20.
The casino package, deposit by deposit
Each step has its own match percentage, cap and spin count. The table shows how the four stages stack up.
| Deposit | Match | Maximum bonus | Free spins |
|---|---|---|---|
| 1st | 100% | £2,000 | 150 |
| 2nd | 100% | £3,000 | 50 |
| 3rd | 50% | £6,000 | 50 |
| 4th | 150% | £4,000 | 150 |
The match percentage drops on the third deposit and jumps on the fourth, so the size of each deposit you make matters more at some stages than others. You only receive what your own deposit earns up to the cap.
Sports and crypto versions
Sports bettors can take a 100% match up to £200 instead of the casino route. Players who deposit in crypto get a separate offer: 200% up to 3,000 USDT for the casino, or 100% up to 200 USDT for sports. Pick the one that fits how you actually play, since they are alternatives to the standard casino package.
Free Spins Explained
Free spins are pre-paid rounds on a slot, set at a fixed stake chosen by the casino. You do not pay for them out of your balance, and any winnings usually arrive as bonus money tied to wagering. The spinboss casino free spins here are attached to deposits, so they land in your account after a qualifying payment rather than on sign-up alone.
Bonus spins versus in-game free spins
Do not mix up the two. Bonus spins come from the casino as part of an offer. In-game free spins are a feature inside a slot, such as the free spins round in Book of Dead or Big Bass Bonanza, triggered by symbols during normal play.
Which slots the bonus spins can be used on is set in the offer terms. Check that list before you claim, and browse the slot lineup to see what you would be playing.
The spins in the welcome package are tied to deposits. If you are looking for spins without paying in first, the no deposit page covers what is and is not available.
The 50 Free Spins Offer
Searches for spinboss 50 free spins usually point to the second and third stages of the welcome package. Each of those deposits comes with 50 spins: the second pairs them with a 100% match up to £3,000, and the third with a 50% match up to £6,000.
The larger spin counts sit on the first and fourth deposits, at 150 each. That means the 50-spin stages are the middle of the journey, not the headline. If you plan to claim only part of the package, the first stage gives the most spins for the smallest bonus cap.
Spins from each stage are credited separately, so keep track of which deposit they belong to. Terms such as spin value, eligible slot and expiry can differ from stage to stage, so read them each time rather than assuming they match the previous one.
Wagering Requirements
The welcome package carries 40x wagering. In plain terms, you must stake the bonus amount forty times before winnings from it can be withdrawn. Until then, the money is locked behind play-through.
What the 40x figure covers
Wagering is normally counted on bets you place, not on what you win or lose. Games contribute at different rates, and slots usually count in full while table games often count for less. The terms for each offer state the exact rules, including whether free spin winnings follow the same multiplier.
What to check before you play
- Whether wagering applies to the bonus alone or to bonus plus deposit
- Which games count and at what rate
- The maximum stake allowed while a bonus is active
- How long you have to finish the requirement
- Whether spin winnings carry their own wagering
Treat 40x as a serious commitment of play. If you would rather not lock funds, you can simply skip the offer when depositing.
How to Claim a Casino Bonus
Claiming is a short process, but the order matters. Opt in before you deposit, because a payment made without the offer selected may not qualify afterwards.
- 1Create your account and complete the registration details.
- 2Open the cashier and look for the welcome offer for your first deposit.
- 3Select the offer, or enter a code if one is requested. The promo code page explains how codes work.
- 4Deposit at least £20 using a method that is eligible for the offer. The deposit guide lists the payment options.
- 5Check your balance for the bonus funds and free spins, then read the active terms.
- 6Repeat for deposits two to four when you are ready, selecting the matching offer each time.
Everything on the spinboss bonus page applies only to players aged 18 or over. Set a deposit limit before you start if you want a firm cap on what you put in.
Other Bonuses for Existing Players
Weekly reload spins
Once the welcome package is behind you, a weekly reload bonus of 70 free spins gives regular players something to come back for. As with the first offer, check the qualifying deposit and the slot the spins are locked to.
Loyalty programme
The casino runs a five-tier loyalty programme. You earn points by wagering, and moving up improves the rewards. Top tiers bring a personal account manager, better point conversion, custom rewards, priority withdrawals and access to high-stakes tables.
Points come from betting, so the programme rewards activity, not just deposits. It is worth knowing how it works if you plan to play for a while, but it is no reason to raise your stakes.
Bonus Terms to Check
A big headline number tells you little until you have read the conditions behind it. Before accepting any offer, go through the terms page for that specific promotion and note the points that affect you most.
Look at the minimum deposit, the wagering multiplier, the time limit and the list of eligible games. Pay attention to restrictions on maximum bets and on how winnings from spins are treated. Offers can also differ by payment method, which is why the crypto and sports versions are separate.
If something is unclear, ask 24/7 live chat before you deposit and keep a copy of the reply. Declining an offer is always an option, and it is better to play without a bonus than to accept conditions you do not understand.
Read the terms first, claim second. The offer only pays off if you can actually meet the conditions.
