777 Super BIG BuildUp Deluxe Demo by Crazy Tooth Studio
777 Super BIG BuildUp Deluxe packs three superlatives into its name, and together they promise a slot that saves its best for the bonus. The return leans the other way. It splits 75.5 points to regular play and 20.7 to the Super Deluxe Bonus Spins, so roughly four fifths of what this slot pays back comes between bonuses, in the part of the game where the BIG BuildUp meters fill.
The reels stand on navy disco tiles, with gold and blue stars shooting in from both sides. Five reels hold 3, 4, 4, 4, and 3 rows of watermelons, grapes, lemons, gold bells, BAR plaques, and blue diamonds. Red-and-white chip stacks with counters perch over the reels, and a gold DELUXE meter crowns the centre, so the collecting is built into the look of the board.
Features and Free Play
The BuildUp Payout
Three things collect above the reels in Crazy Tooth Studio’s BIG BuildUp, and none of them pays by itself. Wild Chips and Multiplier Chips pile up in stacks, while Deluxe Stars feed the Deluxe Prize on the centre reel. On any spin, the BuildUp can trigger at random and pay out what has been collected.
| Collected | What it adds when the BuildUp pays |
|---|---|
| Wild Chips | A wild for each chip, each one adding a row to its reel |
| Multiplier Chips | A win multiplier, one step per chip, up to x5 |
| Deluxe Stars | The Deluxe Prize on the centre reel |
A BuildUp can award one, two, or all three. Because the stacks fill side by side, a single payout can drop extra wilds, add a multiplier, and hand over the Deluxe Prize together. Anything it awards resets once paid, and that stack starts again from nothing.
In free play, that makes the counters the part of the board to watch between bonuses. With regular play earning most of the return, they matter more here than on a slot built around its free spins.
Super Deluxe Bonus Spins
Landing 3, 4, or 5 Bonus scatters anywhere starts 5, 7, or 9 Super Deluxe Bonus Spins. At least one Wild Chip lands on every bonus spin, and its wild adds a row to its reel, then steps down one place a spin until it drops off. Nothing retriggers the round, so the scatter count at the start fixes its length, and no later scatter adds to it.
The bonus is the honest limit here. Its 5 to 9 spins can’t be extended, and anyone drawn in by the Super Deluxe name is playing for the smaller share of the game. 2,201x is the highest figure Crazy Tooth’s own measurements produced, a recorded result rather than a stop built into the game. Lucky Clucks put BIG BuildUp in a barn eight months earlier, laying eggs where this game stacks chips, and the idea first appeared in Banana Drop in 2020. This July 2022 release takes it to the casino floor, and for all the bonus talk in its name, it’s a demo to judge on its regular spins.
How to Play
Pays From Either End
Matching symbols on adjacent reels form a win when their run starts from the leftmost reel or the rightmost one, so every combination can pay in both directions. The reels hold 3, 4, 4, 4, and 3 rows, and multiplying those heights, 3 × 4 × 4 × 4 × 3, gives the 576 ways. The two short reels are the outer ones. Because a win can start at either end, those 3-row reels can open a combination on both sides of the board, not just on the left.
Few slots on the site pay on 576 ways. Deadwood from Nolimit City spreads them over the same 3-4-4-4-3 reel shape, so the layout alone doesn’t set this game apart. The BuildUp stacks do.
The grid doesn’t always stay at 576 ways, either. Each wild that a BuildUp payout or the bonus adds extends its reel by one row, so a reel can stand taller than its starting height while that wild is in play, and every extra row adds to the ways a win can take.
RTP and Bet Range
Crazy Tooth lists the RTP at 96.19%, an average worked out over a huge number of spins rather than a figure any single session will follow. Stakes go from 0.15 up to 30 a spin. There’s no bonus buy, so the only way into the Super Deluxe Bonus Spins is landing the scatters.
With 777 in the name, and fruit, bells, and BAR plaques on the reels, the look is pure fruit machine. The casino chips stacking up over its reels are where this game adds ideas of its own.
