A free online casino typically refers to platforms where players can enjoy casino games without wagering real money, including sweepstakes casinos and social casinos.

Sweepstakes casinos use virtual currencies—Gold Coins for entertainment and Sweeps Coins, redeemable for real prizes—operating legally under sweepstakes laws, allowing players to win cash or prizes without direct gambling.

Social casinos, on the other hand, offer purely entertainment-focused gameplay with virtual credits that cannot be cashed out, emphasizing social features and in-app purchases without real-money rewards.

Why Play Free Online Casinos instead of Real-Money Casinos?

What are Free Online Casinos?

A free online casino is any platform where you can spin slots or play table games without wagering real money. In 2025, that breaks down into three models:

  1. Demo play: free-to-try mode on UK-licensed casinos (e.g. 888, 32Red Casino sites).
  2. Social casinos:  app-based, coin-driven games (Slotomania, House of Fun) with no cash-out.
  3. Sweepstakes casinos: dual-currency sites (Gold & Sweeps Coins), such as WOW Vegas, that allow you to redeem Sweeps for cash prizes.

Risks & Hidden Costs of Free Casinos Online

Free doesn’t always mean “no spend”. Social and sweepstakes sites upsell coin packages. Tip: set a monthly micro-budget or stick to login bonuses.

Because no stake is required, UKGC treats social & sweepstakes casinos as prize competitions, not gambling. They are legal for 18+ and outside GamStop.

Demo Casinos (Play-for-Fun)

Available at most UK-licensed brands. No registration on some sites; others require age check.

Social Casinos

Coins have zero cash value. Popular apps: Slotomania, WSOP Poker. Daily coin drops & leaderboards.

Sweepstakes Casinos

Gold Coins = fun; Sweeps Coins = prize-eligible. Free entry methods keep it legal. For the mechanics, please read our full sweepstakes guide.
