How the Game Plays

Big Bang Bonus: Hold & Win takes place deep within a shimmering gold mine, where the 5x4 grid is filled with gems, mining carts, and explosive TNT. Winning combinations are formed by landing matching symbols across 20 fixed paylines starting from the leftmost reel. The game features a clean, polished visual style typical of OctoPlay titles, accompanied by an upbeat soundtrack and crisp animations. While standard symbols like gold-filled carts offer the highest base payouts, the real action centers on the various bonus symbols that can land on any spin.

Hold & Win Feature Explained

The core of this slot is the Hold & Win feature, triggered by landing six or more Gold Pan, Mystery, or Jackpot symbols. Players are initially awarded three respins on a special grid where only bonus symbols appear. Each new symbol that lands locks into place and resets the respin counter to three. The round continues until the screen is filled or no more respins remain, at which point all accumulated values are paid out.

Dynamic Multipliers and Jackpots

A unique aspect of the gameplay is the five-level Dynamite progression system. Each time a Hold & Win round concludes, the bonus level increases, applying higher multipliers to all cash values in future bonus rounds at that stake level. Additionally, the feature provides access to four fixed jackpots: the Mini (20x), Minor (50x), Major (100x), and the Grand Jackpot worth 1,000x the stake.
