What Are Diamond Slots?
There are many different kinds of diamond slots online, and diamonds are often found in classic slot games. You will find this familiar symbol in luxury wealth-themed games as well, but most people associate this trope with traditional-looking slots with a classic set of symbols. You will find diamonds in both modern video slots and retro slots, and they come with similar features as regular online slots. However, diamond slots may narrow the focus to one main feature, and they are often simpler games than complex video slots.
Features Of Diamond Slot Machines
There is more to diamond slot machines than sparkling gems. While some of these games come with few features, others boast an array of cascading wins, respins, free spins, and multipliers. In short, you can find all sorts of bonus features and modifiers depending on which diamond slot you play, but many of them tend to focus on one or two features. Instant scatter prizes are not uncommon, and you can even win progressive jackpots.
| Feature | Description |
|---|---|
| Wild Symbols | Special symbols that can substitute for other symbols to help form winning combinations, enhancing your chances of a payout. |
| Cascading Wins | Winning symbols disappear, allowing new symbols to fall into place and potentially form a chain reaction of wins on a single spin. |
| Multipliers | Increases the value of winnings by a certain value. May be also encountered in the form of a progressive multiplier, which grows after cascades/free spins. |
| Free Spins | A bonus feature that provides a set number of spins at no cost. Often comes with extra perks and enhanced winning capabilities. |
| Respins | A feature that allows reels to spin again without requiring an additional wager, usually triggered by specific symbols or combinations. |
| Hold and Win | A streak-style respins bonus game featuring cash symbols that get locked in place while other reels spin to accumulate massive rewards. |
| Jackpots | Big cash prizes paid out in specific situations. There are various types of jackpots, such as instant scatter jackpots, fixed jackpots, or progressive jackpots. |
Bonus Rounds on Double Diamond Slots
Being a classic, old-school-inspired 3-reel slot machine, Double Diamond keeps things entirely simple in terms of bonus features, yet it does not hold back on big wins. The highlight of this online slot game is most definitely the Double Diamond wild symbol, which not only substitutes other symbols but also carries a multiplier value to give your wins a nice boost. It is also the highest-paying icon in the game and plays a crucial role in winning big.
One Double Diamond wild landing on a winning payline will double the payout, while two wild symbols on the payline quadruple your winnings. Multiplying like this gives players opportunities of scoring impressive payouts, even without any traditional bonus rounds. It's utterly simple, but highly rewarding.
