4 Supershiny Diamonds: Hold and Win

The game "4 Supershiny Diamonds: Hold and Win" by Playson features a video slot design that incorporates the Hold and Win mechanic, blending a traditional fruit machine aesthetic with contemporary diamond-themed graphics. It operates on a 5×3 grid with five fixed paylines, showcasing classic fruit symbols alongside colorful Diamonds that activate special features. Players can engage in a standard Bonus Game as well as a more extensive Super Bonus Game. The Bonus rounds are initiated when violet, green, or blue Feature Diamonds align with larger Diamonds positioned above the reels during regular gameplay.

During the Bonus Game, players receive three respins, and each time a new Diamond symbol appears, the respin counter resets to three, with symbols remaining sticky throughout the feature. There are three varieties of Feature Diamonds: Multi, which places multipliers on vacant cells or stacks on existing ones; Charge, which reveals additional cells filled with random Diamonds or Jackpot symbols; and Collect, which sums the values of all Diamonds already present on the grid. A unique Super Diamond can only be found in the base game, and its appearance expands the grid to 5×5, leading into the Super Bonus Game.

The Super Bonus Game also employs the Multi, Charge, and Collect mechanics, and filling all 25 cells in the expanded grid grants the Super Jackpot of 10,000× your bet. In the regular Bonus Game, filling all 15 cells results in the Grand Jackpot of 3,000× your bet. An Extra Feature symbol may also show up during the bonus rounds, transforming into a random Feature Diamond to enhance or add features in play. Additionally, players can opt for an Extra Bet, which raises the stake per spin and increases the likelihood of triggering the Bonus Game. There is also a feature-buy option available, allowing players to purchase direct access to the Bonus Game for a fixed multiple of their bet. The maximum potential win in a single round across all features is limited to 15,000× the total bet.
