777 Super BIG BuildUp Deluxe Slot Game Design
You don’t need to work at Baker Street to work out that a slot with the name 777 Super BIG BuildUp Deluxe is going to have a retro fruit-machine vibe. The symbols on the reels are all exactly what you would expect to find on old-school slots, but Crazy Tooth has also managed to make it feel slightly different. The game is very flash, with big animations magnifying the reels and helping to bring the whole experience to life. It’s topped off with a really lively soundtrack and some good old-school sound effects. It feels as though you are playing an arcade game when you spin the reels, and it is a soundtrack that can actually be quite infectious to spin the reels with.

777 Super BIG BuildUp Deluxe Slot Bonus Features
This is a game that is very focused on its bonus features. The first of these is the Big BuildUp. There are three symbols in the slot that are passive, meaning that they don’t pay anything or contribute to combinations. Instead, they are instantly collected in three spots above the reels whenever they land. These are a Wild Chip, a Multiplier Chip, and the Deluxe Star.
The Big BuildUp can trigger at any point in the game, and when this happens, it will allow you to choose one of the three built-up features. The Wild Chip will add extra Wilds to the reels, the Multiplier Chip will add multipliers and the Deluxe will add to your payout. Players will also receive a payout here and this can be up to 4,500x the stake.
The other bonus is the Super Deluxe Round. This sounds much fancier than it is, with it actually just being a Bonus Spins Round. Three, four, or five Scatters will launch 5, 7, and 9 spins respectively. During the Free Spins, a Wild Chip may land on any reel and expand it by one. It will then move down the reels one spot on each spin until it falls off.

There is a lot to like about 777 Super BIG BuildUp Deluxe. The game has a funky design and does, as Crazy Tooth Studios titles tend to attempt to do something different with a well-worn theme and genre. The gameplay can begin to feel a little one-note with the collection elements, but it does pay off when the bonuses are triggered and the winning potential, especially for this kind of game, is strong. With all that in mind, this is definitely a title we would recommend taking for a spin at one of the many top online casinos that will be playing host to it.
