Discovering 777 Super Big Build Up Deluxe
777 Super Big Build Up Deluxe is an online slot game developed by Microgaming, designed to offer players a dynamic experience across five reels. The game features 576 winning ways using the ANY ADJACENT PAYS™ system, enabling wins with matching symbols in any adjacent reels. The title incorporates a range of symbols and bonus features, which are detailed below.
How the Game Works
Understanding the Game Structure
- The main game uses 5 reels, with the first and last reels containing 3 positions, and the central reels each containing 4 positions.
- There are 576 active ways to win, thanks to the ANY ADJACENT PAYS™ mechanic. Matching symbols anywhere on adjacent reels count towards winning combinations.
- To achieve a win, you need 3 or more matching symbols on a way, in neighbouring reels. Only the highest win per way is awarded.
- Winnings and credit awards are calculated by multiplying the way win or credit award by the bet multiplier of the current game.
- The bet multiplier is determined by dividing the credits played by £0.15. For example, a bet of £0.30 results in a bet multiplier of 2.
- All payout tables are updated in real-time to reflect the chosen bet multiplier.
- Winning combinations are clearly marked on the reels. If there are no wins, the player can choose to spin again.
- Any malfunction will void all pays and plays.
Symbols and Their Roles
- Regular Symbols: These symbols form winning combinations when matching symbols appear on adjacent reels along a way. Payouts are determined by your current bet multiplier.
- Wild Symbol: The Wild substitutes for all paying symbols, except Scatter Symbols. It can also form its own winning combinations.
- Scatter Symbol: The Scatter Symbol appears on all reels, except during the Super Deluxe Bonus feature.
- Passive Symbols: These do not contribute to wins.
Exploring the Main Features
The BIG Build Up Feature
- The BIG Build Up Feature may trigger randomly during any spin in the base game.
- This feature can award Deluxe Prizes, Feature Chips, Wild Symbols, or multipliers of 2x, 3x, 4x, or 5x.
- Wild Symbols gained in this feature add an extra symbol position to their respective reel.
- If a multiplier is awarded together with a Deluxe Prize, only the Deluxe Prize is multiplied; otherwise, awarded multipliers affect qualifying way wins.
- The feature concludes when all prizes have been revealed. Credit awards are applied immediately, and symbol wins are awarded after the feature ends.
- The feature’s bet multiplier matches that of the triggering spin. Any feature wins are combined with regular wins.
Super Deluxe Bonus
- Landing 3 or more Scatter Symbols activates the Super Deluxe Bonus.
- 3, 4, or 5 Scatter Symbols award 5, 7, or 9 bonus spins respectively.
- On each bonus spin, chips may appear awarding Wild Symbols. These Wilds stay for the remainder of the bonus, shifting down one position each spin until they exit the game board.
- The number of symbol positions on a reel increases each time a Wild Symbol is awarded.
- The bet multiplier for winnings during this bonus is set by the value in the triggering game.
- All winnings during the bonus spins are collected automatically. After the last bonus spin, the feature concludes, and the Super Deluxe Bonus cannot be retriggered.
- Bonus wins are combined with regular wins.
- Total winnings for the bonus are calculated as the sum of all bonus spins in one session.
Achievements and Paytable
- The game includes a Paytable Achievements feature, allowing players to track their progress and outcomes.
Setting Your Bet and Understanding Limits
- The minimum bet per spin is £0.15, while the maximum bet is £4.95.
- Bet size can be adjusted by using the up or down arrow in the Bet Size box.
- The Balance box displays your current funds.
- The Win box shows the result of your latest spin.
Game Navigation
- The Spin button starts a new game round. This can also be initiated using the spacebar if this feature is available.

- Toggle sound, left-hand console mode, and background motion (when available).
