Sign Up

Mad Slots Casino is handing out 100 no-deposit free spins on Big Bass Splash automatically when you register and complete verification, for players located in United Kingdom only. The spins arrive without a deposit, but they carry a 30x wagering requirement and expire after 7 days. Maximum cashout on the no-deposit spins is capped at approximately $12.50, and full terms apply—read the fine print before you play.

A welcome package that stacks across three deposits

The full welcome package combines a 100% match up to about $250 plus up to 300 free spins, split across the first three deposits. Here’s how it works in practice: make a minimum deposit of roughly $12.50 to opt in, and the match bonus is subject to a 30x wagering requirement on the bonus plus deposit. Deposit bonus cash has a maximum cashout of about $125. The welcome bonus is divided between the first three deposits, so plan deposits accordingly and check the countdown—most bonuses expire in 7 days.

Second and third deposit free spins explained

Mad Slots layers in extra free spins on your second and third deposits. The second deposit awards 100 free spins on Big Bass Splash, and the third deposit gives 100 free spins on Book of Dead, each with the same 30x wagering and roughly $12.50 maximum cashout. These spins are opt-in during deposit and must be used within 7 days, so don’t let them sit unused.

Key rules and responsible play points to know

Before you sign up, note these important limits and rules: only one bonus may be active at a time, the default bonus type is sticky (bonus funds must be wagered before withdrawal), slot games count 100% toward wagering, while table games and live casino titles contribute much less, typically 10% or lower. Wagering contributions, stake limits—maximum stake with an active bonus is about $6.25—and bonus-abuse policies can affect eligibility. Most bonuses, free spins included, expire in 7 days. These offers are restricted to players located in United Kingdom and are subject to full terms and conditions.

Where to use your spins and match funds

Free spins are tied to specific slots—Big Bass Splash and Book of Dead are featured in the welcome sequence—while the match bonus applies to slots broadly. Mad Slots runs titles from Pragmatic Play, Big Time Gaming, Play n GO, and Relax Gaming, so expect modern mechanics and bonus features.
