Gem Rocks, released on February 22, 2018, is a casino game made by Yggdrasil Gaming. Gem Rocks features gigantic humanoids, just like in Yggdrasil’s March 2018 slot game named Easter Island, while the usage of gem-embedded objects resembles that of the developer’s August 2017 slot game called Valley of the Gods. Based on the game play, Gem Rocks’ rival games include Asgardian Stones (February 2018) from NetEnt and Gonzo’s Quest (2011) by NetEnt.

The inspiration behind the name “Gem Rocks” is the game’s huge boulders, some of which are shaped like giant robots and have big gemstones embedded on their chests and other smaller gems glittering elsewhere on their bodies. Gem Rocks players match three, four, five, or six win symbols.

Gem Rocks Game Characteristics
Gem Rocks has 4096 pay lines and a 6X4 grid. There are seven multi-colored monster rocks: a ruby red monster rock, a yellow-gray monster rock, a green-blue monster rock, a blue monster rock, a jade green monster rock, a purple monster rock, and a gray monster rock.

The eight ordinary Gem Rocks symbols are: a golden-and-ruby red, star-shaped gem; a yellow-gray moon-shaped gem; a green-blue round gem; a blue triangular gem; a gray triangular gem; a square jade gem; a purple diamond; and a golden X-shaped gem.

The starting page of Gem Rocks is all about: the monster rocks that progressively enlarge when players have either two, five, or nine back-to-back cascading wins; and standing a chance to win as much as X9000 the staked amount. The Gem Rocks’ coin values are: $0.002, $0.01, $0.02, $0.03, $0.04, $0.05, $0.07, $0.08, $0.10, $0.20, $0.30, $0.40, $0.50, $0.70, $0.80, and $1.00.

After the selected coin values are multiplied by 50 coins, the Gem Rocks’ cash bets appear as follows: $0.10 (minimum bet), $0.50, $1.00, $1.50, $2.00, $2.50, $3.50, $s4.00, $5.00, $10.00, $15.00, $20.00, $25.00, $35.00, $40.00, and $50.00 (maximum bet).

These are the Gem Rocks payouts for three, four, five, and six combinations, respectively. The star-shaped gem pays X20, X40, X60, and X200. The moon-shaped gem offers X10, X15, X25, and X35. The round gem gives X5, X10, X20, and X25. The blue triangular gem pays X5, X10, X20, and X25. The gray triangular gem pays X5, X10, X15, and X20. The square jade gem also offers X5, X10, X15, and X20. The purple diamond offers X5, X10, X15, and X20. The X-shaped gem also pays X5, X10, X15, and X20.

Luckily for Gem Rocks players, there can be multiple wins in a single game round, thanks to the winning combinations that disappear to give way to other dropping down symbols, which can also have newer winning combinations. Particularly, the monster rocks’ size depend with the number of dropdown wins; two, five, and nine back-to-back dropdown wins offer 2X2, 3X3, and 4X4 rocks, respectively. A monster rock can explode to trigger the huge payouts called “Super Big” winnings.

The Gem Rocks software is good and the falling boulder sound effects is on point. The outstanding graphics include the huge mineral ores in the background, the mine dust below the grid when spinning, and the animated monsters’ body language perfectly expressing their thoughts.
