Big Win 777 Bonus Features

Chance Wheel

Chance Scatters can appear on reels 1, 3, and 5. Once you collect 3 of them anywhere on these reels, the Chance Wheel feature will be triggered. Each spin of the Chance Wheel guarantees a win, with prizes ranging from instant wins of x5 to x777, as well as a 1 in 3 chance of activating the Free Spins feature.

Booster Spin

This feature can be randomly triggered on any spin during the base game, creating an exciting and suspenseful experience. Once activated, a super suspense mode will be active on reels 1, 3, and 5, ensuring that you will receive a minimum of 2 Scatters.


This classic feature offers an opportunity to enhance your winnings, adding a touch of excitement to the game. It presents a traditional guess-the-card gamble, where you predict the color of the next card to be drawn. A correct guess doubles your winnings, while an incorrect one takes you back to the base game. For those seeking an even greater challenge, you can try to guess the suit of the next card for a chance to quadruple your winnings. Enjoy the thrill and test your luck!

Big Win 777 Free Spins

This feature grants you 12 spins with an endless re-trigger potential, meaning it can be triggered an unlimited number of times. During the feature, Wilds will stick and spread vertically. When they fill an entire reel, they will be removed for the next spin, giving you a chance to win more Wilds.

By landing 1 or 2 Chance Scatters, you can add an extra 1 or 2 spins to the existing count. If you land 3 Chance Scatters, the Chance Wheel feature will be triggered, awarding instant wins or an additional 20 spins. The win potential can reach up to x5000 your bet.

Big Win 777 Conclusion

While we have become somewhat weary of the abundance of generic wheel-based slots over the years, our enthusiasm was not particularly sparked by the addition of yet another one to the mix. These specialized slots do not necessarily appeal to all players, and it is likely that the developers are aware of this fact. However, in an effort to expand their audience, they have introduced a few extra reels and more paylines than usual. Not to mention the highly coveted 5000x win potential and the element of high volatility. And let us not forget the visually stunning appearance, which undoubtedly captivates one's attention.

Explore our extensive casino list to find the perfect bonus tailored to your preferences. Our featured casinos offer enticing incentives like no deposit free spins, free cash, and free bets. I highly recommend checking out the newly launched online casinos, as they often entice new players with generous free spin offers. Take advantage of these opportunities and elevate your gaming experience!

We do not anticipate that Big Win 777 will become a long-lasting sensation. Once the initial novelty wears off (which is likely to occur within a week or two), it will probably settle into its intended role as a ‘filler' slot. It is the type of game that every developer needs in their catalog to ensure they have something to offer everyone.

Frequently Asked Questions About Online Casino Slots

Question: How do online slots work? 

Answer: Online slots operate similarly to traditional casino slots. When you spin the reels, they will stop and reveal potential winning symbol combinations. Each online casino slot has a specific number of reels and winning combinations to aim for. Certain games provide thrilling bonuses like Free Spins, Wilds, Scatters, Jackpots, and other exceptional in-game features to enhance the gaming experience.

Question: How do Free Spins work? 

Answer: The characteristics of Free Spins may differ based on the game you're playing and the method by which you acquired them, be it through in-game progression or a promotional offer. In most cases, Free Spins are offered as part of an in-game bonus in online slots. Utilizing Free Spins is as easy as spinning the reels during regular gameplay. Online slots often make it clear when you're using a Free Spin. Additionally, Grosvenor Casinos frequently offer promotions where you can win Free Spins.

Answer: A Wild symbol has the power to substitute for any other symbol on the reels, completing winning paylines. However, it's important to note that Wilds cannot substitute for Free Spins, Scatters, or other bonus symbols. Scatter symbols, on the other hand, can appear outside of a winning line while still contributing to a winning combination. This allows for wins beyond the typical win lines.In certain instances, the combination of Wild symbols and Scatter symbols has the potential to unlock in-game bonuses. However, it is important to note that the availability of these bonuses may vary depending on the specific online slot being played.

Nowadays, all casinos offer excellent compatibility with smartphones, and many even provide dedicated apps for both Android and iOS devices. This allows for a seamless and convenient gaming experience, regardless of the platform you choose.

Answer: Megaways is a game formula that boasts a trademarked distinction. It leverages a unique Random Reel Modifier algorithm that dynamically adjusts the active rows on every spin. This ingenious feature enables a heightened potential for an abundance of winning combinations with each exhilarating spin.
