New slots sites may have bigger bonuses and more games while older ones may have a better reputation built up over years. The quality of customer service, security, and user-friendliness can also vary drastically. Ultimately, it’s down to your personal preference as no two casinos are the same.

Good online slot casino sites should have a collection of more than 300 slots, including a good variety of classic, 5-reel and progressive slot games.

No, not all online casinos offer bonuses, but most will offer a bonus of some kind to attract and retain players. Bonuses can come in different shapes and sizes, from welcome and reload bonuses to free spins promotions on the newest slots. You can even get no deposit bonuses, which means you can play for real money without making a deposit first.

The jackpots available will depend on the games on offer at the casino, rather than the casino itself. Some standalone progressive slot machines may have smaller jackpots than progressive jackpots that are linked across a network of casino sites.

No, not all online casinos are safe to use. Only play at reputable online casinos that are licensed, regulated, and have SSL-encryption to keep your personal information secure. All the online casinos we have reviewed and recommended are licensed by respected gaming jurisdictions. That means the security is top-quality, the games are audited, and payouts are regularly checked for accuracy and speed. Do not play at casinos on our blacklist, as these have not passed our tests.
