Bonus features are a major reason players choose one slot over another. One game may focus on free spins, another on multipliers, another on special wilds or bonus buys. But the same feature name can behave very differently from game to game, which is why the paytable and demo mode matter.
This guide explains the common features you will see when opening new games on SlotLab.
Scatters and Free Spins
Scatters often trigger free spins. Many slots award free spins when three or more scatter symbols appear, but the details vary. Some games require scatters on specific reels, some pay scatter wins separately, and some change the number of free spins based on how many scatters land.
In demo mode, open the paytable and check where scatters must land, how many free spins are awarded, and whether retriggers are possible.
Wilds
Wild symbols substitute for other symbols to help create wins. Not all wilds behave the same way. Some are simple substitutes. Some expand to cover a reel. Some carry multipliers. Some become sticky wilds during free spins.
Do not only check whether a game has wilds. Check where wilds can appear, which symbols they cannot replace, and whether they behave differently in the base game and bonus rounds.
Multipliers
Multipliers increase wins by values such as x2, x5, x10, or higher. Gates of Olympus is a familiar example of multiplier-focused tumble gameplay. Other slots may reserve multipliers for free spins, wild wins, or special feature rounds.
Multipliers can make a game exciting, but they often increase volatility. Check whether multipliers accumulate, when they reset, and whether the game lists a maximum value.
Bonus Buy
Some slots let players buy direct access to a feature. In demo mode, this uses virtual credits. On real-money sites where the option is available, it uses real funds. Bonus buy can help you see the feature faster, but it does not automatically make a game better value because the price reflects the feature’s risk and expected return.
SlotLab demos let you observe how bonus buys work without using real money. If you leave SlotLab for real-money play, read the price, rules, restrictions, and local availability carefully.

How to Test Bonus Features
Pick one game and one goal. For example: “learn how wilds work” or “check whether free spins can retrigger.” Spin slowly and compare the paytable with what appears on the screen.
If a game has several features, do not try to understand everything in one session. Study scatters and free spins first, then wilds and multipliers later. This builds better understanding than only watching the virtual balance move up or down.
Bottom Line
Free spins, wilds, scatters, and multipliers are central to modern slot design, but each game uses them differently. Demo mode gives you a no-deposit way to learn those details before deciding whether the game fits your style.
