SlotWhat — gambling made simple

Gambling is an intricate and captivating form of entertainment. Whether you're a newcomer or a seasoned player, we're here to simplify the experience for you — from licenses to wagering requirements, we make everything as transparent as possible.

How we test and score casinos

Every casino on SlotWhat is put through the same hands-on checks before it earns a place in our rankings. We register a real account, make a test deposit where possible, request a withdrawal and read the small print behind each bonus. The result is condensed into a single safety score from 0 to 100, so you can compare operators at a glance without wading through fine print yourself. Here is what moves that score up or down:

• Licensing and regulation — who issues the licence and how strict the regulator is
• Withdrawal speed and payout limits — how quickly you actually get paid once KYC is done
• Bonus fairness — wagering, max bet and game restrictions, not just the headline percentage
• Game range and providers — the studios behind the lobby and the depth of the library
• Support and responsible-gambling tools — live-chat quality, deposit limits and self-exclusion

How to find a good casino

Before you sign up, always check the most important details of any bonus offer:

• the wagering requirements
• the time limits
• any game restrictions
• minimum deposit amounts
• maximum withdrawal limits

Casino bonuses explained

Not every bonus is worth claiming. A welcome offer matches a percentage of your first deposit; free spins let you play specific slots at no extra cost; no-deposit bonuses hand you a small balance just for registering; cashback returns a share of your losses; and reload bonuses reward repeat deposits. The headline number rarely tells the full story — a modest 100% match with 25x wagering is usually better value than a flashy 300% match locked behind 60x. That is exactly why we grade every offer on its real terms rather than its marketing.

Wagering requirements, with a worked example

The wagering requirement is the number of times you must bet a bonus (and sometimes the deposit too) before any winnings can be withdrawn. Say you claim a €100 bonus with a 35x requirement: you need to place €3,500 in qualifying bets before you can cash out. Slots usually count 100% toward this target, while table games often count 10% or nothing at all. Keep an eye on the max-bet limit as well — exceed it while wagering and the casino can void your winnings. As a rule of thumb, we flag anything at or below 35x as fair and treat 50x or higher as a warning sign.

Games and game providers

The quality of a casino is defined in large part by the studios behind its games. Leading providers such as Pragmatic Play, NetEnt, Play'n GO and Hacksaw Gaming release titles every week. Our provider pages break down what each studio does best.

Licensing and player safety

A licence is your main line of defence. The Malta Gaming Authority (MGA) and the UK Gambling Commission (UKGC) are among the strictest regulators — they enforce player-fund protection, independent game testing and mandatory responsible-gambling tools. A Curaçao licence is far more common and cheaper to obtain, so it carries fewer guarantees; it is not automatically a dealbreaker, but it earns a lower safety score unless the operator backs it up elsewhere. We always list the exact regulator on each casino page so you can verify it on the regulator's own public register.

Deposits and withdrawals

The way a casino handles money is one of the clearest signals of how it treats players. Most operators accept debit cards, popular e-wallets such as Skrill and Neteller, bank transfers and, increasingly, cryptocurrencies. E-wallets are typically the fastest for withdrawals, while cards and bank transfers can take several business days. The single biggest cause of delayed payouts is identity verification (KYC), so complete it early rather than waiting until your first cashout. Our payment-method pages break down which casinos support each option and how quickly they pay.

Play on any device

Modern casinos are built mobile-first. Whether you play on desktop, tablet or phone, the games run smoothly in your browser with no download required.
