Gameplay, RTP, and Variance

This four-reel, seven-row slot game features 127 paylines and a traditional theme. Players can enjoy spinning its reels from as little as 20p up to £40 per spin. 777 Mega Deluxe has an RTP of 96.10% which is on the average-to-high end of the scale when compared to other online slots. This is a high variance slot, which means it's designed to pay out infrequently but has the potential to offer large payouts when it does. The ‘7’ symbol is the highest value symbol on the reels and pays out 0.25x your bet. If you want to quicken your gameplay, you can use the autoplay feature which allows you to set your bet per spin plus the number of spins you want, then the game plays automatically. Paytable

Bonus Features

777 Mega Deluxe has three special features – a wild symbol, Respin Insanity feature and bonus spins. There are two wild symbols in the 777 Mega Deluxe slot game and these are also multipliers. The symbols to watch out for are the 2x and 5x multiplier wilds. These symbols will replace other symbols on the reels, except the scatter, to help form new winning combinations and create bigger cash prizes. The 5x wild multiplier will only appear during the bonus spins feature. The main features in this slot game are the Respin Insanity feature and the 2x and 5x wild multipliers. Each position which features a winning symbol will join together to create a respin area. These positions will then respin, but if the 2x wild multiplier is in this area, it will be locked in place. If a symbol lands and matches up with a symbol outside of this respin area, the symbols on the outside area will be added to the respin zone. Further respins will then be awarded and the feature ends when no new positions are added to the respin zone. Lastly, players can trigger the bonus spins feature by landing scatter symbols on the first, second or fourth reels. These scatter symbols will then become either 2x or 5x wild multipliers and will be frozen on the reels for the remainder of the bonus round, along with new multiplier symbols that land on the reels. Players will be awarded four bonus spins and a winning spin will trigger the Respin Insanity feature again.
