3 Energy Diamonds: Hold & Win

Win Lines

All symbols pay from left to right on the defined paylines.

Wild

The Wild symbol substitutes all other symbols except Golden Coin, Special Coin, and Jackpot symbols.

Cash Prizes

There are Golden Coin symbols on the reels, which contain cash prizes with values of 1x, 2x, 3x, 4x, 5x, 6x, 7x, 8x, 9x or 10x. Cash prizes are only collected during the Hold & Win feature. Up to 8 Golden Coin symbols can land on the reels per spin during the Normal Game, and up to 5 during the Bonus Game. If the cash prize values are too big to display, they are instead displayed as bet multipliers.

Energy Diamonds

There are 3 Diamonds above the slot - Increase, Collect, and Expand. When a Special Coin symbol, that corresponds to a diamond, lands on the reels, the respective diamond is charged, and there is a chance for the Hold & Win feature to trigger. Only one Special Coin symbol of each kind can land on the reels per spin during the Normal Game, and up to 2 during the Bonus Game. The graphical accumulation of lightning around the diamonds is purely for visual entertainment and does not have any influence on the triggering of the feature.

Hold & Win

When Hold & Win triggers from a Special Coin symbol, Golden Coin symbols are added to the reels until there are between 5 and 7 present. The feature is also triggered if 6 or more Coin symbols, 1 or more being Special Coin symbols, land on the reels in the same spin.

Hold & Win starts with 3 free spins. The only symbols present on the reels during Hold & Win are Golden Coin symbols, Special Coin symbols, Jackpot symbols 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, excluding empty symbols, that land on the reels are locked and remain until the end of the feature when all prizes on the slot are collected. Special Coin symbols get the following bonus effects during Hold & Win:

Collect - Collects the Cash Prizes of all symbols locked on the reels, up to a maximum of 2000x.

Increase - Carries a Cash Prize with a possible value of 2x, 3x, 5x, 7x, or 10x, that is added to the Cash Prizes of all symbols locked on the reels, except Jackpot symbols, up to a maximum of 50x. Collect symbols can be increased up to 2000x.

Expand - Adds a new empty row at the bottom of the slot, up to 2 times. The Expand Special symbols carry a Cash Prize with a possible value of 1x, 2x, 3x, 4x, 5x, 6x, 7x, 8x, 9x, or 10x.

When the slot is filled with symbols and no new symbols can land, the feature is terminated.

Jackpots

There are 5 jackpots in the game. During the Normal Game when the Jackpot Coin symbol lands on the reels, it grows a jackpot by a specified amount. During Hold & Win, when the Jackpot Coin symbol reveals a Mini, Minor, Major, or Mega Jackpot symbol, the corresponding jackpot prize is awarded. The Grand Jackpot is awarded when the slot has been expanded twice and there are 25 locked symbols on the reels.

The awards are:

Mini jackpot - 25x the stake, grows by 5x up to a maximum of 50x

Minor jackpot - 50x the stake, grows by 10x up to a maximum of 100x

Major jackpot - 250x the stake, grows by 50x up to a maximum of 500x

Mega jackpot - 500x the stake, grows by 100x up to a maximum of 1000x

Grand jackpot - 2500x the stake, grows by 500x up to a maximum of 5000x

The values of the Jackpot Prizes are saved throughout play sessions for the game at the bet settings. The probability of winning jackpot prizes changes as the jackpot values change. When a Jackpot Prize is won, it is reset to the base value.

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