What Are the Key Features and Symbols?
- Regular Symbols: Contribute to winning combinations when matching symbols land on adjacent reels. Payouts depend on your bet multiplier.
- Wild Symbol: Substitutes for all paying symbols, except scatter symbols, and can form its own winning combination.
- Scatter Symbol: Can appear on any reel. This symbol is not present during the Super Deluxe Bonus round.
- Passive Symbols: Do not offer any payout.
- Winning Combinations: Achieved by landing three or more matching symbols on adjacent reels, regardless of their position from left to right. Only the highest win per way is paid.
- Paytable Achievements Feature: Track your unique symbol wins and achievements within the paytable.
How Does the Base Game Work?
- 777 Super Big Build Up Deluxe features a game board with 5 reels, arranged with 3, 4, 4, 4, and 3 rows respectively.
- The game offers 576 active ways to win, following the ANY ADJACENT PAYS™ structure—winning combinations are possible anywhere on the reels as long as matching symbols are on consecutive reels.
- Way wins and credit awards are multiplied by the bet multiplier, which is determined by dividing the number of credits played by 0.15 (for example, a £0.30 bet means a bet multiplier of 2).
- The paytable reflects current payout values based on your selected bet multiplier.
- Winning combinations are highlighted after each spin. When there are no wins, the round ends and you may play again.
- All pays and plays are voided in the event of a malfunction.
What Is the Minimum and Maximum Bet?
- Minimum bet per spin: £0.15
- Maximum bet per spin: £4.95
How Does the BIG BuildUp™ Feature Work?
- The BIG BuildUp™ Feature can activate at random during any spin.
- When triggered, you may receive Deluxe Prize and/or Feature chips. Feature chips may grant Wild Symbols or multipliers of 2x, 3x, 4x, or 5x.
- Each awarded Wild Symbol expands its reel by adding an additional symbol position.
- If multipliers are awarded with a Deluxe Prize, they multiply the Deluxe Prize only. Other multipliers enhance evaluated way wins.
- All feature prizes are revealed during the feature, which ends when all have been shown.
- Feature bet multiplier is set by the bet multiplier of the spin that triggered the feature.
- Credits won during the feature are awarded immediately, with symbol wins granted once the feature is over. All feature wins are combined with regular wins from the spin.
How Does the Super Deluxe Bonus Work?
- Landing 3 or more scatter symbols triggers the Super Deluxe Bonus.
- 3, 4, or 5 scatters award 5, 7, or 9 bonus spins, respectively.
- On each bonus spin, chips can land to award Wild Symbols. Any Wilds awarded will add a new symbol position to their reel for the remainder of the bonus.
- Wild Symbols remain on the reels across bonus spins, moving down one position per spin until they leave the game board.
- The bonus bet multiplier is based on the bet multiplier from the triggering game.
- All winnings are collected automatically during the bonus. The round ends after the last bonus spin and cannot be retriggered. Total bonus wins are added to any regular wins from the triggering spin.
- The maximum stated win is based on cumulative winnings from one bonus session.
