Playson’s glossy Hold & Win release wraps a retro fruit machine in neon polish and stacks three bonus diamonds above a 5×3 grid. The red 7 Wild substitutes for any pay symbol; the real action lives in the bonus round, where up to 3 feature diamonds (Multi, Collect, Charge) can combine to chase a 3,000x full-grid jackpot – or trigger the Super bonus on a 5×5 grid for 10,000x. High volatility, 95.7% RTP, max win 15,000x.

Grid / Paylines / Base Symbols

this slot plays on a 5×3 grid with 5 paylines. Wins form left to right across matching symbols. The bell & BAR is the top pay symbol (10x for 5 of a kind), followed by watermelons (25x), and then grapes, oranges, lemons, plums, cherries (all 50x for 5 of a kind). The red 7 Wild substitutes for any pay symbol and matches the bell & BAR value. No base game features beyond wilds – the slot leans hard on the bonus to generate teeth.

The Four Diamonds / Bonus Trigger

Four rotating diamonds sit above the reels: three smaller feature diamonds (Multi, Collect, Charge) and one large orange Super Diamond. As you spin, matching-color diamond symbols land on the grid and are collected by their corresponding diamond above. When at least one feature diamond collects enough matching symbols, the Hold & Win bonus round triggers randomly. The orange Super Diamond collects super diamonds and may trigger the Super version instead.

Hold / Win Bonus / Mechanics / Jackpots

When triggered, each active feature diamond adds prize diamonds to the grid until 6 diamonds total are present. You enter the bonus with 3 respins. Only blanks, prize diamonds (1x-12x your stake), and activated feature diamond symbols appear. Each new diamond resets respins to 3; the round continues indefinitely until the grid fills or respins expire. Smaller jackpot symbols (Mini 15x, Minor 30x, Major 100x) also land.

The three feature diamonds work like this:

  • Multi Diamond (purple): Places multipliers (x2, x3, x5) on 3 empty positions, or adds to existing multipliers if no empty slots remain. The Multi itself becomes a random value (x2-x10) and boosts all diamond prizes in its positions before collection.
  • Collect Diamond (blue): Collects the value from all present diamond symbols and adds the total to itself. Diamonds stay in place after collection.
  • Charge Diamond (green): Reveals 6 extra positions (may contain blanks, prize diamonds, or jackpot diamonds). Their values are added to the Charge Diamond before the extra positions vanish.

You can bring up to 3 activated feature diamonds into the bonus. Extra Feature symbols may land during the round and convert to random feature diamonds (including unactivated ones, which then activate).

Super Hold / Win Bonus

Landing the orange Super Diamond in base play may trigger the Super version. The grid expands to 5×5 (25 positions). The Super Diamond adds 6 random diamonds to the grid – these may include prize diamonds and up to all 3 feature diamonds. The Super Diamond itself holds a value of 7x-10x and can land again during the super bonus, enhancing or activating features. Filling all 25 positions awards the 10,000x Super Jackpot.

Ante Bet / Bonus Buy

Feature Cost Effect
Ante Bet 1.5x your stake Increased chance to trigger Hold & Win bonus (no hit frequency disclosed)
Bonus Buy 100x your stake Directly purchase a bonus spin; may activate up to 3 feature diamonds or trigger Super bonus

Both options are available to eligible players (not UK). The Ante Bet is tempting but opaque – no disclosed hit rate means you’re betting blind on the uplift.

RTP / Volatility / Max Win

this slot carries a 95.7% RTP, high volatility, and a max win of 15,000x your stake. Bet range is £0.20 to £100. The game demands jackpots to truly hit hard; regular prize symbols offer modest payouts even when boosted by Multi/Collect/Charge modifiers. Base game wins are moderate top-ups at best.

Theme / Presentation

Glossy fruit-machine aesthetic with electrified neon effects. Four shimmering diamonds in different colors crown the grid, with jackpot values stacked below the logo on the left. Dark backdrop contrasts with the neon glow. Upbeat synth-based soundtrack keeps the mood playful. It’s a what-you-see-is-what-you-get visual package – no surprises under the hood.

Pros

  • Hold & Win bonus with up to 3 feature diamonds (Multi / Collect / Charge) combining in one round
  • Super Hold & Win on 5x5 grid with 10,000x full-grid jackpot
  • Regular bonus full-grid jackpot of 3,000x; smaller jackpot symbols to 100x
  • Max win 15,000x stake; bonus buy option for direct purchase
  • Red 7 Wild substitutes for any pay symbol

Cons

  • No base game features except wilds - feels like a grind between bonuses
  • Super bonus often feels shallow: larger grid (5x5) is harder to fill, and you don't always get all 3 features active
  • Regular prize symbols offer limited payouts without jackpot or multiplier boost
  • Bonus doesn't always fire with all 3 features active - 'missing out' feeling is real

FAQ

What are the prize diamond values in the Hold & Win bonus?

Prize diamonds range from 1x to 12x your stake. Jackpot symbols are worth 15x (Mini), 30x (Minor), and 100x (Major). Filling the entire 5x3 grid awards the 3,000x Grand Jackpot; filling the 5x5 Super grid awards 10,000x.

How many respins do you get in the Hold & Win bonus?

You start with 3 respins. Each spin that lands at least one new diamond symbol resets the counter to 3 again. The bonus continues indefinitely until the grid fills or respins expire.

What does the Multi Diamond do?

The Multi Diamond places multipliers (x2, x3, x5) on 3 empty positions. If no empty slots exist, the multipliers are added to existing multipliers. The Multi itself becomes a random value (x2-x10) and boosts all diamond prizes in its positions before the round ends.

What is the RTP and max win?

RTP is 95.7% (high volatility). Max win is 15,000x your stake, achieved through the Super Hold & Win bonus jackpot (10,000x) combined with multipliers and other modifiers.

Can I buy the bonus directly?

Yes. The Bonus Buy costs 100x your stake and awards a triggering spin that may activate up to 3 feature diamonds or trigger the Super bonus round. This feature is not available to UK players.

Editorial rating: 4.2/5

this slot is Playson's glossy take on the Hold & Win formula - solid mechanics, but the base game is a genuine slog and the Super bonus often feels like a missed opportunity. Bonus buy without disclosed hit rates stings. For Hold & Win enthusiasts, it ticks the boxes; for everyone else, it's a what-you-see-is-what-you-get affair with no real surprises. Not a soft ride; the variance has teeth.
