How Gems Bonanza's special symbols work

WILD
This is the WILD symbol and substitutes for all symbols. It appears only as part of WILD GEM and LUCKY WILDS features. The same WILD symbol can connect to form multiple winning combinations with different symbols.

Gems Bonanza features

TUMBLE FEATURE
The TUMBLE FEATURE means that after every spin, winning combinations are paid and all winning symbols disappear. The remaining symbols fall to the bottom of the screen and the empty positions are replaced with new symbols coming from above. Tumbling will continue until no more winning combinations or spin features appear as a result of a tumble. All wins are added to the player's balance after all of the tumbles and spin features resulted from a base spin have been played.
SPIN FEATURES (overview)
In the base game, at every spin, behind normal symbols special colored markings can appear. Whenever a win happens on top of a marked spot it triggers a special spin feature, depending on the color of the mark.
NUCLEAR
Blue mark wins NUCLEAR. After all tumbles resulted from the current spin finish, the screen is cleared of all symbols and new symbols are brought to the screen.
WILD GEM
Pink mark wins WILD GEM. After all tumbles resulted from the current spin finish, all instances of one random symbol present on the screen transform into wild.
SQUARES
Brown mark awards SQUARES. After all tumbles resulted from the current spin finish, random blocks of 2x2 of the same symbol are added in random positions on the screen.
COLOSSAL SYMBOL
Red mark awards COLOSSAL SYMBOL. After all tumbles resulted from the current spin finish, a random block of 3x3, 4x4 or 5x5 of the same symbol is added in a random position on the screen.
LUCKY WILDS
Green mark awards LUCKY WILDS. After all tumbles resulted from the current spin finish, any number between 5 to 15 WILD symbols are added to the screen in random positions.
Feature order
If multiple features are won on the same spin they will play in the following fixed order: NUCLEAR, WILD GEM, SQUARES, COLOSSAL SYMBOL and LUCKY WILDS.
GOLD FEVER PROGRESSIVE FEATURE
At every spin the number of winning symbols that exploded during tumbles is counted and the GOLD FEVER meter fills. When a certain number of symbols is reached the GOLD FEVER feature triggers. The meter resets back to zero when no more winning symbol explode as a result of a tumble. Collect 114 points from a base game spin with tumbles and spin features to trigger the GOLD FEVER. The feature starts after all tumbles and spin modifiers from the current spin end. The feature starts at level 1. During the feature at every level, all spin modifiers are guaranteed to be played once per level, in order and all wins have a win multiplier starting at 2x. Collect enough winning symbols during each level to advance to the next level. Level 2 - Collect 116 winning symbols. Level 2 plays with 4x win multiplier. Level 3 - Collect 120 winning symbols. Level 3 plays with 6x win multiplier. Level 4 - Collect 125 winning symbols. Level 4 plays with 8x win multiplier. Level 5 - Collect 132 winning symbols. Level 5 plays with 10x win multiplier. The feature ends when not enough winning symbols have been collected to advance to the next level or all spin features from level 5 have been played.
BUY GOLD FEVER
The GOLD FEVER FEATURE can be instantly triggered from the base game by buying it for 100X current total bet. The bought feature will start after all tumbles and spin features of the base game spin that triggered it end. To advance through the levels in a bought GOLD FEVER round collect winning symbols as follows: Level 2 - Collect 116 winning symbols. Level 2 plays with 4x win multiplier.

Gems Bonanza: A Pragmatic Play Gemstone Cascade Adventure


Game Overview and Core Mechanics


At first glance, the 8x8 grid of Gems Bonanza is a colourful spectacle. The game does away with conventional reels and paylines, opting instead for the popular "cluster pays" system. A winning cluster is created when five or more identical gem symbols connect either horizontally or vertically. When you score a win, those symbols vanish in a satisfying burst, making way for new gems to cascade down from above, potentially creating chain reactions of consecutive wins from a single spin. The betting range is accommodating, starting at a minimum of $0.20 and going up to a maximum of $100 per spin, making it suitable for both cautious players and high rollers.

Symbols, Payouts, and the Tumble Feature


The symbols in Gems Bonanza are a collection of eight beautifully rendered gemstones, each with its own color and shape, from purple squares to red hexagons. The real magic begins with the Tumble feature. Every winning cluster triggers the cascade: symbols are removed, new ones fall in, and the process repeats until no new winning clusters appear. This mechanic is the engine of the game, creating opportunities for significant payouts from a single initial spin.

Unearthing the Gold Fever Feature


Randomly on any non-winning spin, the Gold Fever feature can be triggered. When activated, between 4 and 8 regular gem symbols are randomly transformed into special Gold Gem symbols. These Gold Gems act as wilds, substituting for any regular gem symbol to help form winning clusters. Also, each Gold Gem carries a cash value multiplier, ranging from 1x to 25x your total bet. If a Gold Gem is part of a winning cluster, its multiplier is applied to that cluster's win. If multiple Gold Gems contribute to a single cluster, their multipliers are added together for a potentially colossal payout before being applied to the win.

The Explosive Bonus Game: How to Trigger Free Spins


The main event in Gems Bonanza is the Free Spins bonus round. To trigger it, you must clear the entire 8x8 grid of all its symbols. This is achieved by landing winning clusters and consecutive tumbles. A meter on the left side of the grid tracks your progress, filling up as you remove symbols. Once every single symbol is cleared, you are awarded 10 free spins. During the Free Spins round, the game introduces special Catalyst symbols. These symbols have different shapes (Cross, Square, Circle, and Diamond) and, when they land, they will destroy all adjacent symbols in specific patterns, dramatically increasing the potential for massive cascades and full-grid clears.

Volatility, RTP, and Winning Potential


Gems Bonanza is classified as a high-volatility slot. This means wins may not land frequently, but when they do, they have the potential to be substantial. The game's theoretical Return to Player (RTP) is 96.55%, which is above the industry average. The maximum win potential in Gems Bonanza is a staggering 5,000x your total bet. This huge win cap, combined with the cascading grid and multiplier features, makes for an exhilarating gameplay experience where any spin can theoretically lead to a gem-filled bonanza. For new players, understanding volatility is key; our Beginner's Guide to Online Slots offers great insights into these concepts.
