777 Super BIG BuildUp II Double Deluxe Online Slot Review

Grapes, golden bells, and red 7s stack the reels of the 777 Super BIG BuildUp II Double Deluxe slot machine. This Games Global / Crazy Tooth Studios slot may have a long-winded title, but it’s a blast to play, as big wins come from valuable Poker chips coins, 777, and diamond modifiers. 

A 3-4-4-4-3 layout gives you 576 different ways to match symbols for a win, helped by wilds that can act as others. The chips, coins, diamonds, and 777s are inactive symbols but if the random Double Deluxe feature is awarded, they come to life. Chips randomly add extra wilds to expanded reels, while coins can apply multipliers of up to 5x, and diamonds duplicate reels. 777s increase the values of any prizes from this feature. Scatter symbols trigger free spins where wilds remain active until they move out of view, and diamonds add duplicate reels throughout.

This is an action-packed slot that you can play across desktop and mobile devices, including at the best new casino sites, for wins of up to 6,496x the stake. The volatility is medium, which makes the average returns of 96.22% exceptionally generous.

How to Play the 777 Super BIG BuildUp II Double Deluxe Slot

Traditional fruit machine symbols dominate the reels, with lemons, cherries, dice, BARs, and other classic emblems sitting against a pink and purple neon city. Poker chips, coins, and diamonds can be seen above reels, ready to unleash their powers at any time. It’s a dazzling sight, with lots of colour, movement, and the 777 Super BIG BuildUp II Double Deluxe slot machine comes with a vibrant soundtrack to go with the bright graphics.

The controls run down the right side of the reels, or underneath if playing on an iOS, Android, or Windows mobile. They include a little pile of Poker chips that you click to reveal 22 different bet options ranging from 0.15 to 37.50 per spin, including when playing with any of the best casino sign up offers. Circular arrow and double arrow buttons launch Autoplay and Turbo modes respectively.

This is a potentially complex game so be sure to read the paytable, reached via the 3 lines on the controls, before staking real money. It has extra details on features like free spins, along with a list of symbol values. An Any Adjacent Pays mechanism means wins come from any 3, 4, or 5 matched symbols on connected reels, but the combination can start anywhere. Sticking with tradition, fruit symbols pay the least, with red 7s worth the most.  

Free Spins & Other Features of the 777 Super BIG BuildUp II Double Deluxe Slot Machine

A wild symbol acts as others if it can then help form extra winning combinations. Chips, diamonds, and coins are inactive symbols that can land on reels 1, 2, 4, and 5 only. Triple 7s are also inactive and only appear on reel 3. 

Randomly, a Double Deluxe Prize can be awarded. Chips can place extra wild symbols onto the reels, while coins award multipliers of 2x, 3x, 4x, or 5x on any win from the spin. Wilds also increase the number of rows on their reels to give more ways to win. Diamonds can trigger reel duplications, splitting a reel into 2 with an identical mix of symbols as the original reel. Two duplicate reels are possible at once, which gives you wins from up to 7 matched symbols. If the 777 symbol is present when Double Deluxe triggers, it increases all prizes from the feature.

Double Deluxe free spins are yours if 3 or more scatter symbols stop on the reels of the 777 Super BIG BuildUp II Double Deluxe slot at once. Chips will always award 1 or more wild symbol to the mix during the free games, and these add a row to their reels, then move down 1 row at a time until out of view. Diamonds will always add 1 or more duplicate reels to the game, although these are not persistent, so the number and position of these changes. 

777 Super BIG BuildUp II Double Deluxe Slot Maximum Wins, Volatility, & Average Returns

The maximum possible win is worth 6,496x your stake, although a relatively low bet limit of 37.50 means a top prize of 243,600.00 from the 777 Super BIG BuildUp II Double Deluxe slot. 

It’s a medium volatility game where over the long-term it pays average sized prizes at an average frequency, although this will vary over the short to medium term. The return to players of 96.22% is another long-term calculation, but it’s exceptionally good for a medium volatility slot.

Our 777 Super BIG BuildUp II Double Deluxe Slot Rating
