The layout is a 5-reel by 4-row grid with 50 fixed paylines. Bets start from roughly 0.10 up to around 100 per spin. The top reported RTP is approximately 96.14%, though as with many Red Tiger titles the exact variant may vary by operator. The game is rated high volatility, and the top win potential is listed at up to 21,026x your bet.

Mechanics centre around cash/bonus symbol collection, progression through “vault levels”, and a Buy-Bonus option.

• Cash/Bonus Symbols: Landing 6 or more Cash or Bonus Prize symbols triggers the bonus mode; new symbols during the bonus reset the spin-count. The game features multiple levels: standard free spins, Cash Box, Cash Safe, Cash Vault, ending with high-jackpot unlock.
• Vault Levels Unlock Mechanics: As you progress levels you unlock new modifiers: a collector mechanism that gathers visible values, symbol transformations into Cash or Bonus Prizes, and in the final level the fixed jackpots (Mini, Minor, Major, Grand) become available.
• Fixed Jackpot Prizes: The jackpot tiers appear in the final progression level, with prizes such as Mini (20x bet), Minor (100x), Major (1,000x) and Grand (20,000x your bet).
• Feature Buy Option:
  • Cash Collect (10x bet)
  • Free Spins (35x bet)
  • Cash Vault (115x bet)
