Free Slots

As of August 27, 2025, Ace Online Casino refreshed its free slots offering, giving players more demo titles and a larger Starburst free-spins promotion. The site now highlights playable demos from major studios and a welcome deal that awards up to 500 free spins on NetEnt’s Starburst when you make a qualifying deposit. You can read the full Ace review here for the latest on promos and support options.

Try free-play demos first — no deposit required

Ace continues to support risk-free demo play across a wide range of slot machines. Demo mode is the best way to learn paylines, special features, and volatility without spending real money. You’ll find instant access to demo versions for many games right from the lobby, including classic 3-reel titles and modern video slots with bonus rounds and tumbling mechanics.

Outside of demo play, the market also offers different no-deposit and sweepstakes-style bonuses. For example, some operators give instant registration rewards (such as 7,500 Gold Coins and 2.5 Sweeps Coins) or tiered first-purchase packages that include Gold Coins and Sweeps Coins. Those offers often carry state restrictions and specific redemption rules, so check eligibility before you sign up — many sweepstakes-style programs exclude states such as AL, CT, DE, GA, ID, KY, LA, MD, MI, MT, NJ, NY, NV, PA, RI, TN, WA, and WV.

Top free slot picks at Ace you can play for free

Ace hosts titles from a long list of providers, so there’s variety for every taste. Here are three standouts you can demo today:

• Roller Derby Slots — A 5-reel, 25-payline video slot from Microgaming (Apricot). Features include a “Let’s Talk Derby Free Spins” bonus, scatter symbols, and coin sizes down to $0.01. Max bet tops out at $250, and the demo makes it easy to learn how the bonus rounds trigger. Read the full Roller Derby review for details.
• Sweet Bonanza Slots — A candy-colored 6-reel video slot from Pragmatic Play with tumble mechanics and up to 15 free spins. It uses cluster pays rather than classic paylines, and demo play is perfect for getting used to the Tumble Feature and multipliers. See the Sweet Bonanza review .
• Anderthals Slots — A 5-reel, 40-payline prehistoric title from Microgaming (Apricot) with expanding wilds, wild multipliers, and multiple free spins features. The demo helps you test the volatility before staking real money. Read the Anderthals review .

Each demo helps you explore volatility, bonus triggers, and typical hit frequency without risking your bankroll.

What the Starburst welcome spins actually require

Ace’s current welcome promotion advertises up to 500 free spins on Starburst. The offer requires a minimum deposit — currently $10 — to unlock spins, and the bonus carries playthrough conditions (the promotion data lists a 65x wagering multiplier). Always read the terms before you accept a bonus: eligibility, wagering requirements, and verification steps can affect how and when you can withdraw winnings.

Play smarter: use demos, check RTP and verification rules

Demo play is a practical way to test return-to-player (RTP) levels and session strategy. Free slots let you:

• Compare volatility so you know whether a game pays smaller, frequent wins or rarer, larger ones.
• Practice bonus-round triggers and understand how multipliers or tumbling reels work.
• Confirm mobile performance and input options before betting for real.

Also note that many operators require identity verification before cashing out promotional wins. Some programs request documents such as government ID, a utility bill, and proof of funds within a defined time frame. Checking those rules up front saves frustration later.
