Gamzix has introduced Only Diamonds, a slot that moves away from visual excess and instead builds its identity around controlled symbol interaction. The release arrives with a 3-5-3 reel configuration and a defined maximum win of 3,500x, placing the focus not on expanding mechanics but on how values are revealed, modified, and ultimately collected.

At first glance, the structure appears compact. The three reels on each side frame a wider central reel, creating a layout that differs from the common five-column grid. Within this frame, two reel positions are treated differently from the rest. These cells are reserved for higher-value symbols, effectively concentrating potential outcomes in clearly defined areas. The design does not attempt to disguise its logic; instead, it makes the distribution of value visible and contained.

The base game sets the tone by introducing three functional symbols: Mystery, Collect, and Upgrade. Rather than acting as isolated triggers, these elements are interdependent. Each spin can become a staged sequence in which symbols do not simply land and pay, but evolve before the final result is confirmed.

Mystery symbols represent the first step in this chain. When they appear, their content is not immediately disclosed. They may reveal fixed multipliers ranging from 1x to 9x the total bet, or they may convert into fixed prizes that can reach up to 50x. This delayed disclosure changes the rhythm of the spin. The outcome is technically determined at the moment the reels stop, yet the visible result remains incomplete until the Mystery symbol resolves.

The Collect symbol then alters the flow. It does not introduce a new prize; instead, it activates what is already present. When triggered, it reveals all Mystery symbols on screen and aggregates their values into a single payout. The effect is cumulative rather than additive across separate paylines. Structurally, Collect functions as a settlement mechanism, consolidating dispersed values into a single, synchronized event.

Upgrade introduces a further layer of recalibration. Its purpose is to move existing symbol values to a higher tier before the payout is finalized. For example, a 9x Diamond can be transformed into a Mystery symbol, reopening its potential rather than leaving it fixed. After adjusting other symbols, Upgrade contributes its own randomly assigned value of up to 9x. The result is not simply an increase, but a reclassification of what was already visible on the reels.

This interaction between revealing, modifying, and collecting creates a contained loop. The mechanics do not rely on cascading reels or expanding grids. Instead, they operate within the established layout, adjusting internal value rather than external structure. The game’s medium volatility profile supports this approach, allowing swings to occur through symbol transformation rather than through prolonged feature chains.

The Bonus Game continues the same logic but introduces controlled repetition. It is activated either by landing three designated symbols on the active row or through a separate Heap of Diamonds event. Once triggered, the feature begins with three respins. Each time a qualifying symbol lands, the respin counter resets, extending the round while preserving its finite nature.

A notable adjustment is made to the bonus layout. Two reel positions apply a filtering system that restricts what can appear. In these cells, only 9x Diamond symbols, Jackpot symbols, Collect, or Upgrade symbols are permitted. Lower-tier outcomes are excluded. This filtering does not guarantee a specific payout, but it increases the concentration of higher-value interactions within defined spaces. The design choice simplifies visual output while narrowing the range of possible symbols.

Jackpot symbols operate alongside the multiplier-based mechanics. While the overall maximum win remains capped at 3,500x, jackpot prizes introduce fixed tiers within the respin cycle. Their inclusion ensures that the bonus round does not rely solely on incremental multiplier growth, but also integrates predetermined reward levels.

Access to the bonus is not limited to organic triggers. Only Diamonds includes two Buy Bonus options. The Standard Buy, priced at 30x the stake, grants entry into the regular bonus configuration. The Super Buy, set at 75x, adjusts the internal weighting to increase the frequency of higher-value symbols during the feature. This two-tier structure does not alter the maximum win ceiling, but it changes how quickly higher-value combinations are likely to appear.

From an operational perspective, the dual purchase model introduces measurable session variance. The base game maintains medium volatility, while the Super Buy option increases exposure within a contained feature cycle. This separation allows for differentiated promotional strategies without modifying the core mathematics of the slot.
