Big Bang Bonus Hold & Win Description
Big Bang Bonus Hold & Win is a mining-themed slot developed by Octoplay. As one of the rising studios on the online gambling market, Octoplay has released a slew of hits so far. The Big Bang Bonus Hold & Win slot machine aims to blow up the reels with its features, adding a new Hold & Win take on the mining genre.
The slot plays on a standard grid with a fixed number of paylines. Like many of its mining-themed brethren, it features pickaxes, sticks of dynamite, and mining carts on the reels. Lining at least three matching symbols from left to right counts as a win, which can be completed with or without the help of a wild.
But unlike classic slots in the mining niche, this one brings something new. We’ll unroll the mysteries of this mine below.

Big Bang Bonus Hold & Win Bonus Features
Aside from the Hold & Win feature, the Big Bang Bonus Hold & Win slot features a few other mysteries to solve.
Mystery Symbols
Up to three mystery symbols can land on the reels on any spin. They reveal cash prizes instead of matching symbols with values up to x15. These can only be won during the bonus feature.
Double Chance
The double chance bet costs 50% extra. When activated, it raises the RTP and doubles the chances of triggering the bonus.
Hold & Win
Six or more coins on the reels trigger the slot’s main feature. Players are awarded with three respins, and only cash, jackpot, and mystery symbols on the grid. Every new symbol resets the respins tally. Above the reels, you’ll see five dynamite levels. Whenever the feature is triggered, the level goes up. Progress is saved between the levels, with each level unlocking multipliers that apply to all wins.
The game’s jackpots can also be won during the Hold & Win feature. They’re fixed prizes as follows:
- Mini: 20x
- Minor: 50x
- Major: 100x
- Grand: 1,000x
