How Purple Diamond works

Purple Collect symbols and blue Bonus orbs

Purple Collect symbols and blue Bonus orbs

The combined trigger is important: six symbols do not all need to be blue orbs. The Diamond Progress Metre and Lucky Spin feature provide additional routes to the bonus. Once the round begins, only Bonus and Collect symbols can land, shifting attention away from ordinary line-paying symbols.

Locked rows are visible before they become active

Three additional rows start locked, each with its own progress metre. Collect symbols unlock these rows one at a time, working from the bottom upward. The larger board is therefore a sequence of opened areas, not an immediately active six-row field.

Symbols can appear on locked rows while those rows are still inactive. A visible prize above the active area should not be counted as an available collection simply because it is drawn on the screen. Its row must first be unlocked. The provider's bonus board makes that separation visible through the lock icons and row boundaries.

Ordinary Collect gathers Bonus symbols below it

Each purple Collect symbol adds one extra spin and absorbs the Bonus symbols beneath it. Its vertical position matters: the stated rule covers the area below the Collect symbol, rather than every symbol anywhere on the expanded board.

Bonus symbols can carry fixed Mini, Minor or Major jackpots, so collection can involve more than an ordinary cash orb. Watch both the extra-spin award and the collection path. These are two effects of the same landing, not two separate trigger requirements.

Super Collect arrives in the unlocked top row

Once the top row is unlocked, yellow Super Collect symbols become available there. Each one adds two spins and absorbs all symbols below it. This is broader than the ordinary Collect rule, which describes collecting Bonus symbols below a purple Diamond.

Because the Super Collect rule includes all symbols underneath, the distinction between accumulated collectors and ordinary orbs matters. The top-row position makes it a different collection opportunity from an early purple Diamond. Grand can also appear as a Super Collect symbol.

The round starts with four spins and can be extended by these Collect awards. Read the remaining-spin display as the current allowance; do not assume that every new symbol resets the game to a generic three-respin counter used by some other Hold & Win titles.

Betting information and jackpot interpretation

The provider images illustrate one configuration's stake and jackpot panel. They do not establish a universal RTP, minimum stake or maximum stake. Purple Diamond's useful comparison point is the spatial collection rule: unlocking space changes which visible prizes can become active and which collectors can reach them.

Grand appearing as a Super Collect symbol is a feature condition, not evidence that a fully expanded board guarantees Grand. Likewise, an extra spin extends the opportunity to collect; it does not guarantee that another useful symbol will land before the remaining allowance is exhausted.

04 / The SlotsCollector take

Verdict

Purple Diamond offers a clear reason to study the board's vertical structure. Opening a row, landing a collector and upgrading to Super Collect each change what the next collection can include.

Its strongest feature is that position has a practical meaning beyond a paying line. Players who prefer a simple cash-coin total may find the locked-row states harder to follow, while those who enjoy staged collection have several distinct decisions to observe.
