Mr Mega Casino Bonuses: Up to £4,200 and 150 Free Spins

The welcome package: 100% match up to £4,200 and 150 free spins

Your first deposit is matched 100%, up to a maximum bonus of £4,200, and comes with 150 free spins. The package is for new depositing players aged 18 and over, and it applies to your first deposit only. The smallest deposit that triggers it is £10.

Your next big win starts here

Get your bonus

The bonus is added automatically when the deposit lands, so claim it before you start playing with the money you paid in. If you would rather play without it, you can ask our support team to cancel the bonus at any time.

Working out 35× wagering on your own deposit

Wagering is set at 35 times your deposit and your bonus added together. So you take the two figures, add them up, multiply by 35, and that is the total you need to stake before the bonus balance becomes money you can take out. Every stake counts towards the total as you play.

The clock runs for 21 days from the moment you claim, so it pays to match your deposit to the amount of play you actually have time for. A £50 deposit means £3,500 of stakes across three weeks, which is roughly £167 a day at £4 a spin, or around 42 spins a day.

Claiming the welcome offer step by step

1. Open your account

   You'll give your full name, date of birth, home address, email, phone number and a payment method, and tick the box agreeing to the terms. You need to be 18 or over.

2. Deposit at least £10

   Open the cashier, pick your method and pay in £10 or more. Visa, Mastercard, PayPal, Skrill, Neteller, Trustly, MuchBetter, Paysafecard, Apple Pay and bank transfer are among the 17 deposit methods we support.

3. Take the bonus before you play

   The match and your spins are credited with the deposit. Claim them before you start spending the deposited funds, otherwise the offer no longer applies to that deposit.

4. Play through the 35× within 21 days

   Keep every stake at £4 or less per spin or round while bonus funds are active, and watch the balance tick down as you clear the requirement.

5. Tell us straight away if something is missing

   If the bonus or the spins don't appear, contact our support team before you place any bets. We can credit a missing bonus or missing free spins at that point, but not after play has started.

Free spins: how they land and how the winnings behave

The 150 free spins in the welcome package arrive with your deposits rather than all at once, and more spins turn up later through our regular promotions. Whatever the source, the rule on the money is the same: winnings from free spins are credited as bonus funds, so they carry the wagering terms of the offer they came from before they can be withdrawn.

Play your way, every day

If the slot named in a free spins offer isn't available in your region, or was advertised wrongly for it, we put the spins on another eligible game instead, with the same number of spins at the same value per spin. The cashier and your account area show which offer your current spins belong to.

Where a bonus code fits in the cashier

Most of our offers need no code at all. The welcome match and its spins are credited automatically with your qualifying deposit, and Daily Picks sit ready in your account area. The place a code does come into it is the cashier: when you deposit with Paysafecard, you enter the amount, add the bonus code in the field provided, and then confirm the card PIN on the Paysafecard site.

One thing worth knowing about targeted offers that arrive by email: only the account the email was sent to can use them. If a promotion reaches you second-hand, the payout isn't honoured on another account even if the wagering has been completed. If you'd rather not see promotions at all, our support team can unsubscribe you or block bonuses on your account before you play.

Bonus eligibility and the deposit rule behind our offers

Unless a promotion says otherwise, our bonuses are for players who have made at least one successful deposit, and a no deposit bonus isn't among our current promotions. The minimum deposit to qualify for a deposit bonus is £20 unless the offer states a different figure, which the welcome package does at £10. If you want to try slots without putting money behind them, hundreds of titles from Pragmatic Play, Playtech, NetEnt and other studios run in demo mode once you've registered.

Account details go through an automatic check after registration, and that check decides whether the account is eligible for bonuses. If it isn't, we email you when the account is created, so you know before you deposit. Bonuses are always credited in the currency your account is set to, which for players here means pounds.

Weekly and daily extras: Prize Twister, Daily Picks and your birthday

Every Wednesday, a qualifying deposit earns you one spin on the Prize Twister, and that spin always lands on a prize. Anything the Twister hands out as a bonus or as free spins follows our standard bonus terms, so check the wagering attached to what you win before you play it through.

Daily Picks are personalised offers waiting in your player area each day, from free spins to bonus funds. What you see depends on the current state of your account, which also means an offer can disappear before its stated expiry if transactions on the account change the picture. Take a look at the start of a session rather than leaving a pick sitting there.

Once a year, the Birthday Bonus arrives as free spins, bonus funds or a cash award. Alongside all of this, My Levels adds points every time you play and moves you up through its tiers as you go.

Tournaments, live roulette missions and prize drops

Slot tournaments run daily as freerolls, as buy-in events and as one-off formats around holidays and special occasions. You join by opting in, by depositing or by buying spins, depending on the format, and then your play on the qualifying slots builds your position.

• Roulette Missions set daily challenges on selected Evolution live roulette tables, with a reward when you complete one
• Drops & Wins by Pragmatic Play pays daily cash prizes, surprise jackpots and multipliers across qualifying slots and live casino games
• Peter & Sons Cash Rain drops random prizes from a daily pool while you play Peter & Sons titles
• Slot tournaments run every day, with buy-in and freeroll entries side by side

Spin today, win today

Join and play

Cash prizes from these events behave differently from match bonuses, because a drop or a tournament prize paid in cash has no play-through attached to it. Where a prize comes to you as a bonus or as free spins instead, the terms of that promotion tell you what wagering applies.

The bonus rules worth knowing before you play

The rules below apply across our promotions at Mr Mega Casino. None of them is complicated, but each one changes what you should do in a given moment, so it helps to know them in advance.

Occasionally a technical misconfiguration credits the wrong number or value of free spins, or the wrong bonus. When that happens we correct it by removing the winnings from the faulty reward and re-adding it set up properly, so you still get the offer as it was meant to be.

We are licensed and regulated in Great Britain by the Gambling Commission. Our connections are SSL encrypted, every account is verified before a first withdrawal, and deposit limits and play limitations sit in your account along with cooling-off, temporary suspension and self-exclusion. The SafeMate tool tracks what you've spent, won, lost and how long you've played. Bonuses are there to extend entertainment, never a way to earn: play with money you can afford to lose, and use the limits if the fun stops. 18+.
