I deposited £20 on a Tuesday evening and had a £20 match plus 50 free spins in my account within a minute. Over the next fortnight I worked through most of the promotions page, and the MadSlots bonus list runs longer than you find at most UK casinos: a three-part welcome package, two cashback offers, reload deals, tournaments and a daily wheel. Two of them need a code. The rest arrive with your deposit or your play.
MadSlots Casino Bonus Types
Offers fall into three groups. New accounts get a three-deposit welcome package. Existing accounts get cashback and reload offers. Tournaments and the daily wheel are open to anyone who has made a deposit.
Welcome Package for New MadSlots Accounts
The welcome package spreads across your first three deposits and adds up to £500 in matched funds plus 80 free spins. MadSlots credits each match as soon as the deposit lands, and you enter no MadSlots casino bonus code. I cleared my first £20 match in four days, withdrew £64, and the money reached my bank the next working day.
1st Deposit
MadSlots matches 100% of your first deposit up to £200 and adds 50 free spins on Book of Dead at 10p a spin. The minimum deposit is £20. You get 7 days to clear a 35x wagering requirement on the bonus, so a £20 deposit means £700 of wagering before you can withdraw. Free spin winnings carry the same 35x. Use the spins within 3 days. I waited for the weekend and lost the last 15.
2nd Deposit
MadSlots gives you 50% on your second deposit up to £150, plus 30 free spins. The £20 minimum, 7-day window and 35x requirement stay the same as the first offer. You need to deposit £300 to reach the £150 cap. Most second deposits land between £50 and £100, so you receive £25 to £50.
3rd Deposit
MadSlots matches 75% of your third deposit up to £150 with no free spins. The 35x requirement and 7-day window stay the same. A £200 deposit earns you the full £150.
While any bonus is active, you cannot bet more than £5 per spin. MadSlots voids winnings from bets above that limit, so lower your stake before you start clearing.
Cashback
MadSlots runs two cashback offers, one for live tables and one for the rest of the site.
Live Casino Cashback
MadSlots returns 10% of your net live casino losses each Monday, up to £250, as cash with no wagering requirement. Lose £200 across blackjack and roulette in a week and you receive £20. Slots losses do not count towards it.
Weekly Cashback
The weekly cashback covers slots and table games. MadSlots calculates it on your net loss for the week, and your total deposits that week set the percentage:
- 5% for £20 to £500 deposited
- 7% for £501 to £1,500
- 10% for £1,501 to £3,000
- 12% for £3,001 and above
- 15% for VIP accounts by invitation
A £300 deposit week that ends £120 down returns £6 at the 5% tier. That £6 bought me one short session of spins.
Live Roulette Weekends
Each Friday at 6pm until Sunday midnight, MadSlots attaches cash drops to specific bets on its live roulette tables. Corner bets and straight-up numbers trigger the larger prizes, which range from £5 to £500. The format changes from week to week, so read the banner in the lobby before you sit down. I hit a £10 drop on a £2 corner bet on my second Saturday.
Free Spins
MadSlots shares 5,000 free spins each week through Reel Rain. Wager £50 on any slot between Monday and Sunday and you enter the draw. Winners receive between 20 and 100 spins, and winnings from them carry a 35x requirement. Every offer on the promotions page needs a deposit, so you will not find a no deposit bonus here.
Other Bonuses
Four more offers sit on the promotions page. Two use a MadSlots bonus code, and you enter it before you deposit.
High Roller Bonus
Deposit at least £250 with the code HIGH40 and MadSlots adds 40% up to £400. You have 3 days to clear a 35x requirement, with one claim per 7 days. Reaching the £400 cap takes a £1,000 deposit, so this offer suits a bigger bankroll than most of us carry.
Friday Reload
Deposit at least £25 on a Friday with the code FRI30 and MadSlots adds 30% up to £100. The offer follows UK time and allows one claim per Friday. I forgot the code on my first attempt, and MadSlots would not add it after the deposit cleared. Support confirmed that rule in live chat within two minutes.
Loyalty Points
You earn 1 point for each £10 you wager on slots, and 500 points convert to £5 in bonus cash. That is £5,000 wagered for £5, a thin rate, though it adds up across regular slot sessions.
Mega Mad Jackpot
MadSlots runs a £50,000 prize pool across a four-week jackpot race on selected slots. Any real-money spin on the listed titles earns you leaderboard points, and any account with a deposit can join.
Mad Wheel
Each day you can spin the Mad Wheel after you deposit £10 or more in the previous 24 hours. Prizes include 5 to 50 free spins, cash from £1 to £25, and an occasional 100% reload. Wheel cash carries a 10x wagering requirement. My second spin landed 10 free spins on Book of Dead, which paid £3.20.
Tournaments
MadSlots runs two competitions. The Slot Race pays out a £2,000 prize pool each day, and you climb the leaderboard by hitting the highest win multiplier on selected slots. The top 100 receive prizes and first place takes £400. The Live Casino Cup runs Monday to Sunday with a £5,000 prize pool, and you earn points for each pound wagered on live blackjack and roulette. The top 30 win. I put £600 through the Cup in one week, finished 41st and won nothing, so check the points table before you commit your bankroll.
How to Claim a MadSlots Casino Bonus
Most of the list needs no code. The welcome package, both cashback offers, Reel Rain, the wheel and the tournaments trigger from your deposit or your play.
Two MadSlots bonus codes sit on the current page: HIGH40 for the High Roller Bonus and FRI30 for the Friday Reload. Type the code into the promo field in the cashier before you confirm the deposit. Sites that list a MadSlots bonus code for the welcome package have it wrong, because that offer needs none. MadSlots rotates its codes from time to time, so check the promotions page for the current MadSlots casino bonus code before you pay.
