777 Super BIG BuildUp II Double Deluxe Slot Review

The 777 Super BIG BuildUp II Double Deluxe Slot Game

I see 777 Super BIG BuildUp II Double Deluxe as a modern twist on a classic fruit machine. Crazy Tooth Studio keeps the 5 reel, 3-4-4-4-3 layout from the first game but drops it into an urban night scene, with skyscrapers lighting up the backdrop. Neon fruits, glossy BARs and casino icons glow on the reels, while an energetic electronic soundtrack drives the pace of every spin.

The game runs on 576 active ways and Any Adjacent Pays, so hits can land from either side, which keeps the grid feeling lively even between features. I like how the minimalist control panel sits on the right, leaving the reels to dominate. For me, the appeal lies in that combination of simple spinning and the promise of Double Deluxe modifiers kicking off at any moment.

Symbols and Payouts – 777 Super BIG BuildUp II Double Deluxe

The paytable in 777 Super BIG BuildUp II Double Deluxe revolves around 11 regular symbols. Watermelon, Orange, Grapes and Lemon sit at the lower end, paying up to around 1.8x your bet for seven of a kind. The three BARs, in blue, gold and pink, form the mid tier and climb to roughly 2x your stake for seven matched symbols on adjacent reels.

Cherries, Bell, Dice and the red 7s act as the top regulars, reaching about 2.6x for seven in a way win. Any Adjacent Pays with 576 ways means those lines do not need to start on the first reel, as long as they sit on touching reels. The wild substitutes for every paying symbol, while the Bonus scatter, Triple Seven, Chip, Coin and Diamond symbols feed into the Double Deluxe features.

777 Super BIG BuildUp II Double Deluxe Slot Bonus Features

The Double Deluxe feature is the heart of 777 Super BIG BuildUp II Double Deluxe. During base play, a special Double Deluxe Prize builds above the central reel. Triple Seven symbols can land only on reel three and increase that prize by roughly 0.13x to 10x your bet. At random, the feature can trigger and award a Double Deluxe Prize anywhere between 8x and 3,000x stake.

When Double Deluxe starts, Chips, Coins and Diamonds come into play. Chips can drop extra wilds on the reels, and the feature can also award multipliers in the 2x to 5x range. Diamonds are the real highlight in my view, as they can duplicate at least one reel, copying its symbols and creating clusters of identical reels that can throw out substantial way wins when the grid lines up well.

Multipliers either apply to the Double Deluxe Prize alone or, if that prize is not awarded, to every winning way during the feature. The other main bonus is Double Deluxe Bonus Spins, triggered by three scatters in the base game. Here, Chips add persistent wilds that slide down one row each spin while extending their reel’s height, and Diamonds can duplicate reels on every bonus spin, although the free spins round itself cannot retrigger.

How to Win at 777 Super BIG BuildUP II Double Deluxe Slot

When I load 777 Super BIG BuildUp II Double Deluxe, I first set a stake between 0.15 and 37.50 per spin using the chip button on the control panel. The grid runs on 5 reels with a 3x4x4x4x3 setup and 576 active ways. Wins land whenever three or more matching symbols appear on adjacent reels anywhere, left to right or right to left, with only the highest win per way paid.

777 Super BIG BuildUp II Double Deluxe Slot RTP & Volatility

Stat wise, 777 Super BIG BuildUp II Double Deluxe sits at a 96.22 percent RTP with medium volatility and around 27.68 percent hit frequency. In practice, that gives me a steady mix of smaller way wins, punctuated by stronger rounds when Double Deluxe or the Bonus Spins fall into place. The maximum advertised payout is 6,496 times stake, which is decent, though a touch lower than some high impact slots I play.

The Final Thoughts on 777 Super BIG BuildUp II Double Deluxe

After a good number of sessions, I rate 777 Super BIG BuildUp II Double Deluxe as a fast, feature heavy fruit slot that suits medium risk players. The constant prospect of Double Deluxe firing, combined with sticky sliding wilds and reel duplications in the bonus spins, keeps the game feeling alive. The main drawback for me is that the top win sits slightly under many modern jackpot figures.

On the other hand, the Any Adjacent Pays system, 576 ways and frequent modifiers give plenty of entertainment even on modest stakes, though the 37.50 ceiling might not satisfy high rollers. Some of the passive symbols and prize logic take a couple of play sessions to fully grasp, but once they click, the structure feels straightforward enough for regular gambling while still offering a fresh spin on the classic 777 theme.
