777 Super Big BuildUp™ Deluxe™ Theme, Graphics, and Sounds
Admittedly, 777 Super Big BuildUp™ Deluxe™ does not showcase the most original theme under the sun. The grid is set against a blue background decorated with white stars, while images of bells, gems, lucky 7s, and cherries adorn the reels. The stunning graphics and smooth animations will satisfy every casino enthusiast. The background music creates a relaxing atmosphere.
Despite its retro theme, 777 Super Big BuildUp™ Deluxe™ will not go unnoticed thanks to its unusually sized grid. In addition, it offers a mind-boggling number of win lines that are sure to spark the interest of many reel spinners. If we had to describe 777 Super Big BuildUp™ Deluxe™ in a few words, we would say that the game is a classic slot with a modern twist.
777 Super Big BuildUp™ Deluxe™ Symbols and Payouts
777 Super Big BuildUp™ Deluxe™ is a slot with an unusual grid. It features 5 reels, 3-4-4-4-3 rows, and 576 active win lines. One of the most appealing aspects of this slot is that winning combinations can be formed from left to right and right to left. To collect a payout, 3 or more matching symbols must land on a win line. The game’s paytable displays the winning symbol combinations as well as how much you can win with a specific bet.
777 Super Big BuildUp™ Deluxe™ has 11 winning symbols. The watermelon, orange, grapes, and lemon pay a maximum of 0.47x the stake for five of a kind. These symbols pay 0.2x and 0.3x the stake for three and four matches, respectively. The game features three differently colored BAR symbols. Players who land 3, 4, or 5 identical BAR symbols will collect payouts of 0.27x, 0.4x, and 0.5x the bet, respectively.
The golden bell, blue gem, lucky 7, and cherry icons are the most valuable regular symbols in the game and share the same payouts. These symbols pay 0.33x, 0.53x, and 0.73x the stake for 3, 4, and 5 matching symbols on adjacent reels.
The game makers have also included a wild symbol that substitutes for all paying symbols. The bonus symbol acts as a scatter and can appear on all reels. Note that the scatter icon cannot land on the reels during the Super Deluxe Bonus.
777 Super Big BuildUp™ Deluxe™ Bonus Mechanics
The slot’s main attraction is the BIG BuildUp feature. It triggers randomly, giving casino enthusiasts the chance to benefit from the Deluxe Prize or Feature Chips. The Deluxe Prize ranges from 4x to 3,000x the stake, depending on the number of Deluxe Stars collected.
The Feature Chips, or passive symbols, do not produce a payout. Instead, they land on top of other icons and are collected above the reels. The Feature Chips are represented by a Wild Casino Chip, a Golden Multiplier Chip, and a Golden Deluxe Star.
The Wild Casino Chip appears on reels 1, 2, and 4 to award wild symbols. These extra wilds add a symbol position to their respective reels during the BIG BuildUp feature. The Golden Multiplier Chip is collected on top of the last reel and increases the multiplier by 1. When a Golden Deluxe Star symbol lands on the third reel, you will collect a multiplier between 1.33x and 10x, which is applied to the Deluxe Prize total.
When you play 777 Super Big BuildUp™ Deluxe™, you can win 5, 7, or 9 free spins if 3, 4, or 5 scatter symbols land on the reels. During the free-spins bonus round, you will be awarded additional wild symbols if one or more Wild Casino Chips land on the reels. These wild symbols add an extra row on top of the reels. Each wild symbol remains on the grid and moves down by one position with every spin until it disappears from the screen. The feature ends once you run out of free spins.
Closing Thoughts
If you are looking for a slot that boasts impeccable graphics and is compatible with your smartphone or tablet, 777 Super Big BuildUp™ Deluxe™ is the game for you. Although 777 Super Big BuildUp™ Deluxe™ is a retro-themed slot, it is not your typical fruit machine. The game stands out from the rest with unique features and an unusual layout. The bonus features are engaging and easy to understand.
The addition of passive symbols that do not directly produce a payout yet unlock various bonus features is an interesting decision by the software company. We noticed that this game evokes the spirit of another slot from Crazy Tooth – 777 Mega Deluxe. However, 777 Super Big BuildUp™ Deluxe™ offers more features and a whopping payout of 15,000x the stake.
