Key Features and Gameplay Mechanics

Reels, Rows, and Win Lines

Coins & Diamonds: Hold and Win uses a straightforward 5x3 setup with 5 fixed win lines. Wins pay left to right, starting from the first reel, keeping the action simple and the pace fast. This minimalist layout is perfect for players who prefer clean, classic gameplay without clutter.

Paying Symbols and Payout Flow

The paytable leans into a retro Vegas vibe with fruit-machine staples and shimmering icons. Premium symbols deliver the stronger line wins, while special symbols—Golden Coins, Stars, Diamonds, and Jackpot icons—steal the show when it’s time for the Hold & Win bonus. In the base game, your best moments often come from lining up premium symbols while you angle to trigger the bonus feature.

Base Game Flow and Autoplay

Spins are brisk, with smooth transitions and punchy on-reel effects. Use autoplay for hands-off sessions with your preferred spin count and stop conditions (where available). Because this slot emphasizes frequent, smaller hits in the base, it’s well-suited to extended sessions and bankroll-friendly play.

Boost/Double Chance (Where Available)

Some versions of the game include an optional feature boost (often called Double Chance) that increases the odds of triggering Hold & Win for a slightly higher stake. If you love bonus rounds and want more frequent entries, consider toggling it on—just remember it also raises your cost per spin.

Bonus Features and Special Mechanics

The bonus design is the headline act in Coins & Diamonds: Hold and Win, combining familiar respin rules with unique symbol interactions for escalating prizes.

Hold & Win Bonus Round

Trigger the Hold & Win feature by landing the required number of cash symbols in a single spin. The grid clears and locks in the triggering values, awarding 3 respins. Each new cash, Star, Diamond, or Jackpot symbol that lands sticks in place and resets the respin counter back to 3. When you run out of respins—or fill every position—the bonus ends and your total is paid.

This mode is all about momentum. The more positions you lock, the bigger the finish—and if you manage to fill the entire 5x3 grid, you’ll score the Grand Jackpot for a huge payout.

Star Symbols: Prize Boosters

Star symbols boost the value of visible cash prizes, powering up the amounts already locked on the grid. Stars can deliver significant escalations—perfect for turning a promising feature into a memorable one. It’s a high-impact mechanic that rewards you for building a strong board and then supercharging it.

Diamond Symbols: Collect and Amplify

Diamonds are your best friend in this slot. When a Diamond lands during Hold & Win, it collects all visible cash prizes on the reels and can copy them—dramatically lifting your total round value. Diamonds can also land with sizeable values of their own, with prize potential that can climb up to four figures in multiplier terms. Land a Diamond at the right moment, and your feature can explode in value.

Wild Symbols

Wilds substitute for regular pay symbols in the base game to complete line wins. While they don’t carry multipliers, they help smooth out the hit rate and keep your balance rolling while you hunt for the bonus trigger.

Fixed Jackpots: Mini, Minor, Major, Grand

Four fixed jackpots can appear via special Jackpot symbols during the Hold & Win round: Mini, Minor, Major, and Grand. The Grand Jackpot is awarded when you fill all 15 positions on the grid, delivering a spectacular 5,000x prize. This clear ladder of jackpot targets gives you constant goals as the board fills.

Bonus Buy (Where Available)

Prefer to jump straight to the action? Some versions of Coins & Diamonds: Hold and Win include a Bonus Buy, letting you purchase immediate entry into the Hold & Win feature. Availability depends on your location and local rules, so check the in-game menu. It’s a fast-track option for players who live for the respin round.
