How Biggest Vault Works

Free Spins: 6+ Cash or Bonus Prize Symbols

Land 6 or more Cash or Bonus Prize symbols in a single spin to trigger Free Spins. You start with 3 spins; only Cash, Bonus Prize, or empty symbols can land. Every new symbol resets the counter back to 3. All Cash and Bonus Prize symbols stick until the round ends, either after 3 spins with no new symbols or when the grid is full.

At the end of each of your first four Free Spins rounds, the game advances to the next Progress Level, unlocking more power for the next time you trigger Free Spins.

The 4 Progress Levels Explained

• Level 1: Cash Box
• Level 2: Cash Safe
• Level 3: Cash Vault (unlocks Vault Spins)
• Level 4: Bonus Prizes (Mini, Minor, Major, Grand)

Cash Symbols can show multipliers such as 0.5x, 1x, 2x, 3x, 5x, 7x, or 10x.

Feature Breakdown

Cash Box (Level 1)

• Can land on reels 2, 3, and 4 once Level 1 is unlocked.
• Collects the value of all Cash and Bonus Prize symbols on the reels, but leaves them in place.
• If multiple Cash Box symbols hit, each one collects the full values.
• If 6+ Cash/Bonus Prize symbols are present, they trigger Free Spins and keep their values.

Cash Safe (Level 2)

• Can land on reel 3 at Level 2 and beyond (cannot appear with Cash Vault in the same spin).
• After line wins pay, transforms all Royal symbols into random Cash or Bonus Prize symbols, then collects the values — leaving those symbols on the grid.
• If Cash Safe and Cash Box land together, Cash Box collects after Cash Safe transforms the Royals.

Cash Vault and Vault Spins (Level 3)

• Cash Vault can land on reel 3 at Level 3 (not in the same spin as Cash Safe).
• Transforms all Royals into random Cash or Bonus Prizes and collects everything, leaving symbols in place.
• Triggers Vault Spins with an increasing Multiplier:
  • The Multiplier starts increased by +1 for each Cash symbol already on the reels (Bonus Prizes do not affect it).
  • Every new Cash symbol that lands is multiplied by the current Multiplier.
  • At the end of each spin, the Multiplier increases by +1 for each new Cash symbol that landed.
  • Bonus Prizes are not multiplied and do not increase the Multiplier.
  • Vault Spins end after 3 spins with no new symbols or when the grid is full.

Bonus Prizes (Level 4)

• Unlocks special Cash Symbols: Mini (20x), Minor (100x), Major (1000x), Grand (20,000x).
• Only one Grand can appear, and it cannot land more than once in a single spin or feature.

Feature Buy Options

Skip straight to the action with three buy options. When you use Feature Buy, the game temporarily switches to a new state with all features unlocked, your normal state is saved and restored afterward, and wilds cannot land during these bought rounds.

• Cash Collect: Guarantees 1+ Cash symbols plus either a Cash Box or Cash Safe in the spin (40x stake).
• Free Spins: Guarantees 6+ Cash symbols to trigger Free Spins immediately (30x stake).
• Cash Vault: Guarantees a Cash Vault symbol and launches Vault Spins with an increasing Multiplier (80x stake).
