Each Diamond symbol that lands on the reels fills up the container above the slot and has a chance to trigger the Hold & Win feature, instantly adding Diamond symbols to the reels until there is a minimum of 5 present. The filling of the container above the slot is purely for visual entertainment and does not have any influence on the triggering of the feature. The feature is also triggered if 5 or more Diamond symbols land in the same spin.

The Hold & Win bonus starts with 3 free spins. Each time a Diamond symbol lands on the reels, the free spins are reset to 3. During the Hold & Win feature, only Diamond symbols and empty symbols can land on the reels.

During the Hold & Win feature, all symbols that land on the reels are locked and remain until the end of the feature. When there are no free spins left, all Diamond symbols receive prizes. Blue Diamond symbols can receive any of the Cash Prizes, Gold Diamond symbols can receive any of the Jackpot prizes, except the Grand Jackpot prize, and Red Diamond symbols can receive any Cash or Jackpot prize, except the Grand Jackpot prize. If 15 symbols are locked on the reels, the Grand Jackpot Prize is awarded, and the feature is terminated.

Red Diamond symbols have a chance to land and lock on the reels until a feature is triggered. A Red Diamond symbol is guaranteed to land on the first spin when launching the game for the first time. If the guaranteed Red Diamond symbol has landed, and locked Red Diamond symbols are saved throughout play sessions for the game at the bet settings.

• 1x Cash Prize is boosted by +1x

There are Jackpot Prizes with values of 15x, 25x, 50x, 100x, 250x, and 1000x next to the slot. The Jackpots are:

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