3 Supercharged Diamonds: Hold and Win Slot Review and Free Demo
Written by: Filip Gromovic Reviewed by: Nashon Khamala
3 Supercharged Diamonds: Hold and Win caps wins at 10,000x the stake on a 3×3 grid with 5 fixed paylines, more than nine times the 1,057x top win of Playson’s earlier Diamonds Power: Hold and Win on the same layout. The jump comes from three colour-coded bonus features, Expand, Multi and Stepper, which can all run in one Hold and Win round.
Playson released the slot on 14 May 2026 with classic symbols: 777 Wilds, bells, dice, BARs and card suits. Four fixed jackpots pay 15x, 30x, 100x and 1,000x the stake, and two bonus buy options cost 75x and 200x. Playson has not published a single RTP: casino listings run from 94.49% to 95.50%, below the 95.66% of Diamonds Power: Hold and Win, and rate the volatility high.
Play 3 Supercharged Diamonds Free Demo
The 3 Supercharged Diamonds demo is the quickest way to learn how the three coloured Diamond counters above the reels shape each bonus round. The game is built in HTML5 and runs in the browser, so free play needs no download or registration, and you spin for fun with virtual credits instead of real money.
The demo shows the same 3×3 grid, 5 fixed paylines, Special Diamonds and Hold and Win round described on this page. Four things are worth tracking while you play:
- Which Special Diamond colours are in play when the bonus triggers, since they set the feature mix for the round.
- How often a lone Diamond fires the Extra Diamonds Feature and starts the bonus anyway.
- Where Multi cells build up on reels 1 and 3, and how high a single cell climbs on the way to 32x.
- How far a Stepper Diamond travels down the reel and how many times it gets collected.
The table below sums up the specs behind the demo.
3 Supercharged Diamonds Key Facts
The slot packs a 10,000x cap, four fixed jackpots and two bonus buys into a 3×3 grid with 5 fixed paylines. Casino versions differ in RTP and stake limits, so those rows show the listed range rather than one figure.
| Parameter | Value |
| Provider | Playson |
| Release date | 14 May 2026 |
| Grid | 3×3, expands to 3×5 in the bonus |
| Paylines | 5 fixed |
| Stake per spin | 0.20 to 100 (lower caps at some casinos) |

The next section walks through a spin from stake to bonus trigger.
How to Play 3 Supercharged Diamonds: Hold and Win
Base spins pay on 5 fixed paylines, while the Diamonds that land decide when the Hold and Win round starts and which features it brings. The base gameplay takes a few spins to learn:
- Set the stake. Listed limits run from 0.20 to 100 per spin, and some casinos cap the range lower, for example 0.10 to 20 at one Dutch-licensed casino.
- Spin the 3×3 grid. Three matching symbols on one of the 5 lines pay from left to right, and the 777 Wild substitutes for every symbol except Diamonds.
- Land Diamonds on all three reels. That starts the Hold and Win round with three respins.
- Check the colours. Green, yellow and violet Special Diamonds combine with the matching Diamonds above the reels and add Expand, Multi or Stepper. Every round gets at least one feature.
- Watch for Extra Diamonds. Any Diamond in the main game can randomly trigger this feature, which adds enough Diamonds to start the bonus.
- Or buy the round. 75x the stake buys one to three random features, and 200x buys all three.
Example: Diamonds land on reels 1, 2 and 3 in one spin, and one of them is a yellow Special Diamond. The round opens with Multi active, so multipliers can build on reels 1 and 3 during the respins. What each feature does inside the round is covered next.
Bonus Features in 3 Supercharged Diamonds
All bonus value comes from one Hold and Win round, shaped by three Special Diamond features, a Collect Diamond and four fixed jackpots. The features can run alone or together, which changes how far a single round can go.
Hold and Win Bonus Game and Collect Diamond
The round starts with three respins, and every new Diamond resets the counter to three. Only Diamonds land during the round. A Collect Diamond can land only on reel 2, holds its position until the round ends and gathers the value of the Bonus Diamonds that land, then adds that total to the win.
Example: a Collect Diamond lands on reel 2 on the first respin. Over the next respins three Bonus Diamonds land, each one resetting the counter, and after three empty respins the Collect Diamond adds all three values to the total win.
Expand Feature (Green Diamond)
The green Special Diamond grows the bonus grid from 3×3 to 3×5, from 9 positions to 15. More positions mean more room for Diamonds and Jackpot Diamonds to land. With Multi also active, reels 1 and 3 hold 10 cells that can carry multipliers instead of 6.
Example: on the expanded grid a Diamond can land on the fourth or fifth row of reel 3, positions that do not exist on the base 3×3 layout.
Multi Feature (Yellow Diamond)
The yellow Special Diamond adds multipliers to reels 1 and 3 that start at 2x and double each time another lands in the same cell, up to 32x. The ladder runs 2x, 4x, 8x, 16x and 32x. A Diamond that lands on a multiplier cell has its value multiplied by that cell.
Example: a 2x multiplier lands on the middle cell of reel 3. Two more land on that cell on later respins, taking it to 8x, so a Diamond that then lands there counts at eight times its value.
Stepper Feature (Violet Diamond)
The violet Special Diamond keeps Bonus Diamonds on the reels and moves each one down one position after every respin, so the same Diamond can be collected more than once. If the respin counter reaches zero while a Stepper Diamond is still on the grid, respins continue until it moves off.
Example: a Diamond lands on the top row of reel 1. On a 3×3 grid it passes through the middle and bottom rows on the next two respins before it leaves; with Expand active it has five rows to travel.
How the Three Features Combine
Three features give seven possible bonus setups: each feature alone, any two together, or all three. The 75x buy assigns one to three features at random, while the 200x buy starts with all three. With Stepper and Multi both active, a Diamond moving down reel 1 or 3 can pass over multiplier cells, and Expand gives it five rows of cells to cross.
Example: with all three features active, a Diamond lands on the top row of reel 1 on the 3×5 grid. Over the next four respins it steps through four more cells, and any of them may already carry a multiplier between 2x and 32x.
Fixed Jackpots
Four Jackpot Diamonds can land at any point in the Hold and Win round and pay fixed amounts from 15x to 1,000x the stake. They are fixed values, not progressive pools.
| Jackpot | Pays | At a 1.00 stake | Share of the 10,000x cap |
| Mini | 15x | 15 | 0.15% |
| Minor | 30x | 30 | 0.3% |
| Major | 100x | 100 | 1% |
| Grand | 1,000x | 1,000 | 10% |
The Grand covers one tenth of the cap, so the rest of a top-end win has to come from Diamond values, Multi multipliers and repeated Stepper collections. Supercharged Clovers: Hold and Win, another Playson Hold and Win title, sets its Grand at 5,000x, five times the Grand here.
Extra Diamonds Feature
Any Diamond that lands in the main game can randomly trigger the Extra Diamonds Feature, which adds enough Diamonds to start the Hold and Win round. It gives a second route into the bonus on spins that would otherwise miss.
Example: a single Diamond lands on reel 2 and reels 1 and 3 show none. If Extra Diamonds fires, Diamonds are added to the other reels and the round starts from that spin.
Bonus Buy Options
Two buy options skip the trigger: 75x the stake for a round with one to three random features, or 200x for a round with Expand, Multi and Stepper all active. Availability of the buy can differ between casinos.
| Option | Cost | Features in the round | Cost at a 0.50 stake |
| Bonus Game buy | 75x | 1 to 3, picked at random | 37.50 |
| All-features buy | 200x | Expand, Multi and Stepper | 100.00 |
Example: at 0.50 per spin, the 200x buy costs 100.00 and guarantees the 3×5 grid, the multiplier cells and Stepper movement in the same round. Between bonus rounds, the base game pays from the paytable below.
Symbols, Paytable and Paylines
Base-game wins need three matching symbols on one of 5 fixed paylines, read left to right, and the 777 Wild pays the most at 50x the stake. The Wild substitutes for every symbol except Diamonds, and Diamonds have no line pay of their own. Only the highest win on each line pays.
| Symbol | 3 on a payline (1.00 stake) | Role |
| 777 Wild | 50.00 | Top line pay, substitutes for all symbols except Diamonds |
| Bell | 25.00 | Line pay |
| Dice | 20.00 | Line pay |
| BAR | 15.00 | Line pay |
| Heart, Spade and Diamond card suits | 3.00 | Line pay |
| Club | 1.00 | Line pay |
| Green Special Diamond | No line pay | Adds Expand to the bonus |
| Yellow Special Diamond | No line pay | Adds Multi to the bonus |
| Violet Special Diamond | No line pay | Adds Stepper to the bonus |
| Collect Diamond | No line pay | Reel 2 only, collects Bonus Diamond values |
| Jackpot Diamonds | 15x to 1,000x | Bonus round only |
Example: at a 1.00 stake, 777, 777 and Bell on one line pay as three Bells, 25.00, because the Wilds stand in for the missing Bells. Line wins top out at 50x, so the 10,000x ceiling depends almost entirely on the bonus round, which shapes the RTP and volatility picture below.
RTP and Volatility of 3 Supercharged Diamonds
Playson has not published a single RTP for 3 Supercharged Diamonds: Hold and Win, and casino listings range from 94.49% to 95.50%. Return to player (RTP) is the share of stakes a slot pays back over a very long run of spins, so the casino’s version decides which figure applies.
Casino listings rate the volatility high, 4 out of 5 on one scale. With line wins capped at 50x and a 10,000x ceiling, most of the value sits in the Hold and Win round, which fits that rating.
| Metric | 3 Supercharged Diamonds | Diamonds Power: Hold and Win | Diamonds Power XXL: Hold and Win |
| Released | May 2026 | November 2023 | November 2025 |
| Grid (reels x rows) | 3×3, 3×5 in bonus | 3×3 | 3×5 |
| Paylines | 5 | 5 | 15 |
| RTP | 94.49% to 95.50% (casino listings) | 95.66% | 95.60% |
| Volatility | High (casino listings) | Medium | Medium-high |
| Max win | 10,000x | 1,057x | Not confirmed |
Against Diamonds Power: Hold and Win on the same 3×3, 5-line base, this slot gives up at least 0.16 percentage points of RTP and moves from medium to high volatility in exchange for a cap more than nine times higher. Because the figure depends on the casino’s version, the game’s info screen at the casinos listed below shows which RTP applies before you stake.
3 Supercharged Diamonds vs Other Playson Hold and Win Slots

Each step changes the bonus field: a fixed 3×5 grid in the XXL game, a 3×3 grid that can expand to 3×5 here, and a 5×5 Super Bonus Game in 4 Supershiny Diamonds.
| Slot | Released | Bonus field (reels x rows) | Top prize | Signature mechanic |
| 3 Supercharged Diamonds: Hold and Win | May 2026 | 3×3, 3×5 with Expand | 10,000x cap, Grand 1,000x | Expand, Multi and Stepper |

| Supercharged Clovers: Hold and Win | 2024 | 5×3 | Grand 5,000x | Four fixed jackpots |
Diamonds Power: Hold and Win suits players who want the same compact layout with medium volatility. 4 Supershiny Diamonds offers a bigger 5×5 field with a 10,000x Super Jackpot, and Supercharged Clovers puts more weight on its 5,000x Grand. 3 Supercharged Diamonds is the pick for a feature mix that changes from round to round on a 3×3 base.
