The anticipation is building among players, knowing that some huge cash prizes are on the menu thanks to something new at our casino site. It's called 777 Super Big BuildUp, a five reel online slot that has added value ready to trigger at any time. It's not just one bonus feature either, as you have double trouble in both the BIG BuildUp feature as well as the Super Deluxe bonus feature. On the one hand, there are reel boosters sitting above the reels that can drop in at any time, and the other sees up to 9 free spins that players can use to kick back and see the cash roll in.
This is another in a recent flurry of online slot games coming out of the Microgaming stable, only this time under the studio name of Crazy Tooth Studio. You might have seen a few releases from this powerhouse in recent times, among them 6 Jewels and Sonic Links, with all meeting a fairly high standard. With 777 Super Big BuildUp there's something a bit different, as the five reels see the rows go 3, 4, 4, 4 and 3. However, the rows do expand at times. Instead of seeing the 576 paylines pay only left to right, the paylines pay both ways, which is quite a little slice of generosity from Crazy Tooth Studio. Traditionalists will also appreciate the theme, being one that slot machines down the decades have been using for ever – fruits.
This is one of the online slots by Crazy Tooth Studio that's come out with the highest maximum win amount we've seen in some time. It goes as high as 15,000x your stake, and while still not as high as some of the releases we saw earlier in the year, that's still a great number. The studio also decided not to make the wagering window too broad, with a minimum stake limit of 0.15 and a maximum of 30. So, what we have is a window that allows the cautious players in it more for entertainment than riches limits to make them comfortable, and higher bet numbers for the iGamers in it to win it.
As you will remember from what we mentioned above, the theme of 777 Super Big BuildUp is that of fruits. Watermelon, grapes, oranges and lemons are the fruits that can form 3, 4 and 5 of a kind winning combinations, but there are symbols that carry higher values. These are blue BAR, orange BAR, red BAR, a bell, a diamond, cherries and the famous 7. You find three passive icons that don't form winning combos in the grid, but rather lie above the reels in the 777 chip, the gold star coin and a gold star.
The bonus symbol is simply titled BONUS, while you’ll also have a wild symbol. The wild subs all regular icons to help form winning combinations.
Trying to explain the Big BuildUp feature is tricky to explain, because even when playing it you'll struggle to understand what's going on. The easiest way to understand is that it can trigger at any time, at complete random. Those three passive symbols get collected when they land, and depending on what you've collected when the feature triggers, is what will be applied to the reels. The various boosters consist of multipliers. There’s also the Deluxe Prize that can be awarded when the Big BuildUp feature triggers, and this is a possible 3,000x your stake.
Something a little easier to explain is the free spins feature, titled the Super Deluxe bonus. Landing 3, 4 or 5 bonus symbols will reward 5, 7 or 9 free spins. Things that upgrade the feature are landing wild chips, and this expands the rows of the reels to increase the number of paylines.
Is this a fun game to play? It will depend on what kind of player you are. 777 Super Big BuildUp is one of those slots online where many will sit and wonder what is actually happening at times. If you like to understand the inner working of a slot and fully embrace the bonus features, then you'll have an excellent time. If you just want to win cash and cut through the clutter, then there's a huge selection of slots you can play here that provides a basic and rewarding experience.
