Big Bang Bonus: Hold & Win Slot Information

The game’s design is based on a miner's theme, with the 5X4 game grid positioned at the entrance of a gold mine. If you want to boost the gaming experience for a cost, use the Double Chance in the screen’s top left corner. All other buttons, including the Spin and Bet Size buttons, can be found in the right corner. You can play Big Bang Bonus: Hold & Win on all mobile devices, desktops, and tablets. You create a winning combination by landing 3 or more of the same symbol types on adjacent reels starting at the leftmost reel. 

The lower-paying symbols are 10, J, Q, K, and A. Landing 5 of the same symbol type pays 2X. The higher-paying symbols are a hatchet, a spade, a backpack, and a trolley of gold. Landing 5 of the same symbol type pays between 5X and 50X. 

The game’s Wild Symbol has the design of a barrel with the text “Wild,” and creating a win with 5 Wild Symbols awards a direct payout of 50X the bet. The Cash Symbol is the image of a gold pan with values up to 5X the bet. The Mystery Symbol is a question mark, and up to 3 Mystery Symbols can land simultaneously, revealing values ranging from 10X to 15X the bet.

Mini Jackpot on reel 1
Hold & Win

Wild Symbol

The Wild Symbol substitutes all symbols except the Cash, Mystery, and Jackpot Symbols and helps you create winning combinations. Creating a winning combination with 5 of this symbol type will award a direct payout of 50X the bet.

Cash Prizes

Up to 8 Cash Symbols can land on the same spin, carrying values of 1X, 2X, 3X, 4X, or 5X the bet. Its value can only be collected during the Hold & Win feature, which you can read more about later in the review.

Mystery Symbol

Up to 3 Mystery Symbols can appear on the reels on each spin. They can reveal cash prizes of 10X, 12X, or 15X the bet, which can only be collected during the Hold & Win feature.

Hold & Win

This feature can be triggered by landing 6 or more Cash, Mystery, and Jackpot Symbols, awarding 3 respins. The feature can also be randomly triggered by any landing Cash, Mystery, or Jackpot Symbol during the Base Game. Only Cash, Mystery, blanks, and Jackpots can appear during the feature, and whenever one of these symbols lands (except the blanks), they are locked in position until the end, and the respins are reset to 3 again.

There are 5 Dynamite Levels displayed above the reels, with a starting level of 1. Each time a Hold & Win feature is triggered and finished, it moves to the next level. Progress is saved throughout the session. Each level unlocks multipliers that can be applied to the Cash, Mystery, and Jackpot Symbols. When a symbol with a multiplier is collected, its cash prize is multiplied by the multiplier.

The game’s Jackpots are Mini, Minor, Major, and Grand, awarding 20X, 50X, 100X, and 1000X the bet. The feature ends when no more respins remain, and players are rewarded with the total sum of all locked symbols on the reels.

Double Chance

You trigger the Double Chance at the extra cost of 50% of the current bet. When this feature has been activated, you play the game with an RTP of 95.85%, and the chances of triggering the Bonus Game double.

Big Bang Bonus: Hold & Win Slot Conclusion

This game provides a fun theme and colorful design! Octoplay can’t get enough of Hold & Win releases, and this is another edition to their series, with previous releases such as The Grand Rooster: Hold & Win and Shaolin Panda Hold and Win. Although we’ve seen the theme before, Octoplay has created a light-hearted vibe and fun design, creating a good slot environment.

So, what about the gameplay? As mentioned, this is another Hold & Win game from Octoplay, with gameplay similar to previous releases. A helpful Wild Symbol can score some decent wins during the Base Game, but without the ability to collect any of the Cash or Mystery Symbols, it was just a long wait for the Hold & Win to trigger. When triggered, it carried similar mechanics as we’ve seen before, offering Jackpots up to 1000X the bet and Mystery Symbols up to 50X. So this game offers nothing new? No, the provider has included a Dynamite Level, which is increased each time the Bonus Game is triggered. Each level contains a Total Multiplier value, which is applied to all Jackpot, Cash, and Mystery Symbols, clearing a direct path to the max win of 5,050X the bet.

Overall, with an explosive miners theme, Big Bang Bonus: Hold & Win offers an enjoyable gaming experience, but it lacks an innovative touch to get us excited. To be more favorable to players, we wish to see Wild Multipliers or a Cash Collect during the Base Game, but it still works if you like previous Hold & Win games from the provider.

Big Bang Bonus: Hold & Win is a slot where players can head down the gold mine in search of Jackpots and a new, fresh Dynamite Feature.
