Big Bang Bonus: Hold and Win

Win Lines

All symbols pay from left to right on the defined payline

Wild

The Wild symbol substitutes all other symbols except Gold Pan, Mystery, and Jackpot symbols.

Cash Prizes

Up to 8 Gold Pan symbols can land on the reels on each spin during the normal game. Gold Pan symbols contain cash prizes with values of 1x, 2x, 3x, 4x, or 5x the stake.

Golden Pan symbols are only collected during the Hold & Win bonus. If the cash prize values are too big to display, they are instead displayed as bet multipliers.

Mystery

Up to 3 Mystery symbols can land on the reels on each spin. Mystery symbols contain cash prizes with values of 10x, 12x, or 15x the stake. Mystery symbols are only collected during the Hold & Win bonus.

Gold chunks

On each spin during the normal game, all Gold Pan, Mystery, and Jackpot symbols that land on the reels throw gold chunks equal to their multiplier above the slot. Each chunk has a chance to trigger the Hold & Win bonus. The visual effects are purely for entertainment and do not have an influence on the chance for triggering of the feature.

When a gold chunk triggers the Hold & Win bonus, Gold Pan symbols are added to the reels until there are between 6 and 8 symbols that participate in the triggering of the bonus.

Hold & Win

The Hold & Win bonus is guaranteed to trigger if a total of 6 or more Gold Pan, Mystery, and Jackpot symbols land on the reels at the same time. The Hold & Win feature starts with 3 free spins. The only symbols present on the reels during Hold & Win are Gold Pan, Mystery, Jackpot, and empty symbols. Each time a symbol lands on the reels, excluding the empty symbol, the free spins are reset to 3.

During Hold & Win, all symbols that land on the reels, excluding the empty symbol, are locked and remain until the end of the feature when all prizes on the slot are collected.

Up to 6 Gold Pan symbols can land on the reels on each spin during Hold & Win. If the slot is filled with symbols and no new symbols can land, the feature is terminated.

Dynamites

There are 5 levels to the bonus represented by Dynamite sticks above the slot. The game begins at level 1. Each time the Hold & Win bonus is triggered and played through, it goes to the next level. The level of the bonus is saved throughout play sessions for the game at the stake settings.

Each level unlocks multipliers equal to the level for the Gold Pan, Mystery, and Jackpot symbols. When a symbol with a multiplier is collected, its cash prize is multiplied by the multiplier.

Jackpots

There are 4 jackpots in the game. When a symbol corresponding to a jackpot lands on the reels during the Hold & Win bonus, its prize is collected. Only 1 symbol corresponding to each jackpot can land on the reels per spin. The jackpot awards are:

Mini jackpot - 20x the stake

Minor jackpot - 50x the stake

Major jackpot - 100x the stake

Grand jackpot - 1000x the stake

All symbols pay from left to right on adjacent reels starting from the leftmost.
