How Eternal Diamonds is built
Eternal Diamonds is a Las Vegas-themed Pragmatic Play slot where almost everything leads to one feature: a respins round played on 15 positions. The base game is essentially about collecting coloured chips until that round begins.
Pragmatic Play lists the RTP at 96.50%. The provider page does not publish a volatility rating or an overall maximum win, so those are not stated here. The two biggest numbers the provider does quote are 125x for a single cash value and 10,000x for filling the grid.
The structure will feel familiar to anyone who has played hold-and-respin games, but the three chip colours give it its own identity, since each colour is tied to a different modifier.
What do the chip pots do?
Blue, red and green chips that land in the base game are collected in matching pots above the reels. Those pots are the trigger mechanism, and they can randomly set off the bonus game.
When the bonus begins, it awards three initial respins with up to three modifiers. With three colours and up to three modifiers, the best-case start has all three effects active together.
Pragmatic Play does not publish how full a pot needs to be before it can trigger, so treat the pots as a visual guide to what is building rather than a countdown.
What does each chip colour add?
Each colour links to a different modifier, and they suit different situations.
Blue adds multipliers of up to 100x to random grid positions. Pragmatic Play calls these position multipliers, and with values of up to 100x, blue is the modifier with the highest ceiling.
Red activates a special expanding respins feature. The provider describes it by name without full detail, so the demo is the best place to see exactly how it changes the round.
Green adds one to the initial respins count for every green chip that triggered the feature. A round that normally starts on three respins can start on more, giving each empty position extra time to fill.
How do the respins play out?
During respins, only two kinds of symbol can land: diamond money symbols and chips, both carrying cash values of up to 125x. No other symbols can land until the round ends.
Each new diamond or chip resets the respins counter and stays on the grid until the feature ends. This is the classic sticky respin loop: the round continues as long as new symbols keep arriving before the counter runs out.
Chips have an extra role inside the bonus. They can randomly activate additional modifiers, so a chip landing mid-round can switch on an effect that was not part of the original trigger.
How is the bonus paid, and what is the 10,000x prize?
When no respins remain, the game adds up every cash value on the screen and pays the total. Any position multipliers from the blue modifier form part of that final count.
Filling all 15 positions awards an additional 10,000x prize on top of the collected values. That figure is a separate bonus for a full grid rather than the value of any single symbol, and it is the largest number Pragmatic Play attaches to the game.
Because each new symbol resets the counter, reaching a full grid depends on symbols continuing to arrive before the respins run out, and extra starting respins from green chips give the round more time. The prize sits far above the 125x cap on individual values, which shows how much weight the game places on completing the grid.
Watching the Eternal Diamonds demo
The demo is best used to learn how often the chip pots trigger and which combinations of modifiers tend to appear. Note which colours were involved each time the respins round started.
Inside the bonus, count how many positions are filled when the counter runs out. That quickly shows how far a typical round falls short of 15 and how much green extra respins or chip-triggered modifiers help.
Finally, look at how the blue multipliers are placed. Their value depends on whether cash symbols land on the boosted positions, so some rounds will feel far stronger than others with the same modifiers.
Slotscritic verdict
Eternal Diamonds is a focused respins game with a neat twist in its three chip colours. Blue for multipliers, red for expanding respins and green for extra spins give each bonus a different starting shape, and the 10,000x full-grid prize gives every round a clear, if distant, target.
The only published specification is the 96.50% RTP, so anyone who wants volatility or a maximum win figure should check the in-game rules first.
Checklist: RTP 96.50%, three initial respins with up to three modifiers, blue multipliers up to 100x, green adding one respin per triggering chip, cash values up to 125x and an extra 10,000x for all 15 positions.
