Demo credits or free spins? What really lies behind free slots in the browser

Clicking on “Play for free” prompts the site to ask for an account or a bonus code. Whether you play with play money or accept a bonus with terms and conditions is stated in the small print. Here’s what to look out for before you commit.

Demo credits or free spins: What do you get with "free"?

Demo credits are play money. You are playing with virtual currency that has no monetary value. You cannot withdraw any money. The law calls such games “free entertainment offers” (Gaming State Treaty 2021, § 6j). This refers to games that function like gambling but cost nothing and do not dispense any money. In our opinion, the demo mode of a slot falls under this category. Other ways to play without your own money, We will describe this in a separate article.

Bonus free spins are free game rounds that a provider advertises. For example, they offer them to new customers as a welcome offer, sometimes with a bonus code. This is a code that you type in to receive the offer. You can then withdraw the winnings as real money if you meet the conditions. We do not mean free spin rounds that a slot itself triggers as a bonus feature.

Do you need an account for a demo game?

Whether you need an account does not reveal the difference. Allowed providers are also allowed to offer demo games only to players with a game account (§ 6j, paragraph 1). Some sites offer demo games “without registration”. The difference does not matter here. What matters is another question: can you win money with it? If a browser game remains empty after logging in, blocked third-party cookie files may be to blame. How to check this in Chrome is shown in our guide Browser game does not load after logging in.

What's the catch with free spins?

The catch lies in the surrounding conditions. Four points determine whether you receive any profit from a win:

1. Deposit: “No deposit” is sometimes only valid for the free spins, not for the entire offer. If a provider demands money or payment details before you can read the terms and conditions, cancel the transaction.
2. Revenue (“50-fold”): You must wager a certain amount multiple times before you can withdraw your winnings. “Revenue” here refers to your own in-game bets, not the revenue of a company.
3. Time limit: The offer is valid for a fixed period of time; in the example below, 3 or 7 days.
4. Payout limit: The provider sets the maximum amount you can withdraw.

With "50x", it's the amount of the bet that matters. That can be the bonus money or your winnings from the free spins. The provider writes this in the terms and conditions.

This is what an advertised offer looked like on October 9, 2026

How this looks in practice is shown by an offer from the start page of the comparison portal Spielhallen. It consisted of two parts with their own conditions:

• Part 1, 50 free spins without deposit: You need a bonus code. You must wager the winnings from the free spins 50 times. You can only withdraw a maximum of 50 euros. The offer is valid for 3 days.
• Part 2, Deposit bonus: You deposit at least 10 euros. You must wager the bonus and deposit 40 times. The offer is valid for 7 days.

The minimum deposit of 10 euros therefore only applies to part 2. This is an example, not a rule for all providers. If a promotion specifies a minimum deposit and turnover only once for everything together, it is unclear whether the free spins already require a deposit.

What "50-fold" means in euros

Let’s say you win 20 euros with the free spins. With “50x”, you then have to bet 20 × 50 = 1,000 euros before you can withdraw. So you keep playing, and the bets count. That’s the real catch: While you’re using the 1,000 euros, you can also lose your balance. How exactly the provider calculates this is stated in the terms and conditions. In this example, you can only withdraw a maximum of 50 euros. Even after the 1,000 euros bet, the withdrawal is not guaranteed.

Can the provider do that in Germany?

Yes, if they are on the GGL whitelist. The GGL is the Joint Gaming Authority of the countries. Their whitelist is the official list of all providers with German license. Public gambling in Germany requires this license (according to the 2021 Glücksspielstaatsvertrag, § 4 Abs. 1). For slots that the GGL calls “virtual slot machines”, according to the GGL FAQ, the GGL is responsible. This is how you check a provider:

1. Open the Whitelist of the GGL (As of October 2, 2026) and filters by „Virtuelle Automatenspiele“.
2. Look for the exact Internet address and the operator of the offering. The brand name alone is not enough.
3. Check the provider's homepage. Allowed providers must indicate their license and the regulatory authority there. They must also be reachable at an address with the .de suffix (§ 6e, paragraph 3).

A license from abroad does not replace the German permit. Those who offer online gambling in Germany also need a permit. This is written in the Federal Institute for Public Health (BIÖG). For example, a license from Malta or Curaçao does not count. Free spins also prove nothing. According to GGL, unauthorized providers often advertise with free bonus or free spins. The security symbol in the address bar does not help here. According to the Chrome help, it only shows that the data you send to the page remains private. It says nothing about the license.

What happens if the provider is not on the list?

According to GGL, both illegal gambling and offering and participating in it are punishable (§§ 284, 285 StGB). Furthermore, no authority checks the provider; it is uncertain whether they will pay out. If the operator is not on the whitelist, do not use the offer.

The two-minute check: finding and maintaining conditions

Take two minutes to read the terms before registering. Start browser games without installing them in a tab; often after a short registration (more on this in our post about the trend in browser games). So it’s just a short walk to the account. With the page search feature, you can find the terms quickly. Press Ctrl + F or F3, then Chrome opens the search bar for the current page. Press Ctrl + G to jump to the next result. Search for these German words:

• „Einzahlung“Which part of the offer requires money?
• „Umsatz“, „umsetzen“ or „fach“How often do you need to use it?
• „Gültigkeit“How long is the offer valid for?
• „Auszahlung“Is there a maximum limit?
• „Bonuscode“Do you need a code?

Read the relevant results and open the linked full terms and conditions. The search will only show you where you need to look.

Take a screenshot of the terms before registering. With Windows + Shift + S you take a screenshot, as our screenshot guide shows. If the offer changes later, you have a record of the previous status.

When to let go of an offer

These four warning signs speak against an offer:

• You don't find any conditions, or they don't clearly state which part of the offer applies to what.
• The provider wants money or payment details before you can read the terms and conditions.
• The operator is not on the whitelist, or the home page does not list any German license.
• You cannot answer any of the four questions regarding the withdrawal: deposit, turnover, deadline, withdrawal limit.

Our conclusion: If you just want to try it out, a demo game from a provider on the whitelist is enough. If you’re attracted by a bonus, first read the terms and conditions, calculate the turnover, and check the provider on the whitelist. If you don’t receive a response, reject the offer.

This is how we researched: We analyzed the Gaming State Treaty of 2021, the GGL and BIÖG information pages, the Chrome help and a publicly advertised offer from October 9, 2026. We did not test any offers or create any accounts. Status: October 9, 2026, scope of application: Germany.
