Amazon’s Diamonds Slot Review: Stacked Wilds and Free Games

Amazon´s Diamonds™ is a compact five-reel, three-row slot whose bonus is governed by a notably specific scatter condition. Up to 30 lines run from left to right, and the Diamond is a stacked Wild that can substitute for ordinary symbols. The Crystal Ball scatter also appears stacked, but only on reels two through four. Seven to nine of those scatters trigger between eight and 30 free games, played with the triggering game’s stake and line settings. The resulting structure puts a premium on reading where symbols can land: the Wild supports regular lines, while the scatter feature depends on a high count across a restricted part of the grid.

A compact 30-line layout

The exact online game is described as a 5×3 video slot with up to 30 win lines. Five matching symbols must connect from left to right along a line. The Amazon’s Diamond is a stacked Wild and substitutes for every symbol except the Scatter. A stack can cover several visible positions on its reel, increasing the chance that a line has the symbol it needs; it does not bypass the left-to-right sequence or substitute for the feature trigger. The shape of the grid is therefore simple, while the stacked symbol can make an individual reel more influential to several line paths at once.

There is a source discrepancy worth preserving accurately: Greentube’s online page labels the game type as 5×3 but its separate Reels field says “3 Reels.” The exact-title SlotCatalog listing also identifies a 5×3 layout and 30 paylines, resolving that internal field conflict in favor of five reels and three rows. The review uses that corroborated 5×3 configuration. No exact RTP, maximum win or release date was confirmed for this edition, so none is inferred from similar titles.

A scatter trigger with a narrow landing zone

The Crystal Ball is the Scatter and is stacked, but it can land only on reels two, three and four. Seven, eight or nine scatter symbols across those positions award eight to 30 free games. The official online text does not map each qualifying count to a specific number of games, so it would be misleading to assign a precise eight-to-nine-scatter schedule. What is clear is the threshold and range: fewer than seven do not meet the stated trigger, while more qualifying scatters lead into the awarded feature range.

The free games retain the stake and win-line settings of the triggering game. That continuity makes the bonus a continuation of the chosen setup rather than a separate mode with newly selected settings. The feature cannot retrigger, so it has a fixed end once the awarded games have been played. This sets a meaningful limit alongside the demanding trigger: even after the bonus begins, its duration is determined at entry and cannot be extended by another scatter event.

How the two special symbols differ

The stacked Diamond and stacked Crystal Ball might look like parallel modifiers, but their jobs do not overlap. Diamonds help construct line combinations as substitutes; Crystal Balls count toward the free-games threshold and are restricted to the middle three reels. Because the scatter requirement is seven to nine symbols, the feature relies on multiple stacked appearances within those allowed positions. A Wild stack can improve ordinary combinations without moving the game closer to its trigger. Conversely, a scatter stack contributes to the feature count but is not described as a line-paying Wild. Keeping that distinction in mind explains why a busy reel is not automatically useful in both ways.

Strengths and weak points

Strengths

The symbols have cleanly separated roles: stacked Diamonds support line formation, while restricted Crystal Balls build toward a distinct, easy-to-identify bonus threshold.

Weaknesses

Seven scatters are required within only reels two through four, and the resulting free games cannot retrigger; the bonus is both demanding to enter and finite.

Our Editor’s View

Amazon’s Diamonds suits players who appreciate compact grids and clearly differentiated special symbols. Its central design choice is the contrast between a helpful stacked Wild and a scatter whose landing area and trigger count are tightly defined. That makes the base game straightforward to read, but the free-games feature is a less frequent prospect by its stated seven-to-nine-scatter requirement. Once triggered, the bonus preserves the original stake and lines, then ends without retriggering. The conflicting official reel fields deserve care when comparing specifications; the exact-title corroboration supports the 5×3 reading used here. With RTP and maximum payout unconfirmed, the most useful expectation is mechanical rather than numerical: a simple line structure surrounding a constrained, fixed-length bonus.
