Play!Theme, Graphics and Sound
The mine backdrop is static, so there is little background animation. The artwork on the individual gems is detailed and crisp, like pieces from a jewellery set. The audio loops, so you may want to mute it after a while, but the sound effects do their job: they signal wins and the start of the bonus, and a distinct effect plays on each cascade.
The game does little to reinvent the formula. If you want a straightforward cascading video slot with a bonus feature, it fits the bill. You can find more in the Real Time Gaming slot range.
Symbols and Paytable Basics
The paytable has 9 common symbols, 5 low-paying and 4 high-paying, plus 2 special symbols.
- Low-paying: five rough, uncut stones in different colours.
- High-paying: a cut emerald, ruby, sapphire and purple diamond. The purple diamond is the highest-value common symbol.
- Wild: the rainbow stone substitutes for any other common icon.
- Scatter: the yellow lightning bolt triggers the bonus when enough land in a single spin or after cascades finish.
Cascades and Multipliers
Gem Strike is played on 5 reels and 3 rows with 25 fixed paylines. Each time a winning combination lands, the winning symbols disappear and new icons drop in. Cascades continue until no new win forms. Each win raises the multiplier, up to x3. The game is rated as medium volatility, and bets run from 0.01 to 0.25 coins.
Bonus Spins
Hitting 3, 4 or 5 Scatters during a single spin or cascade awards 15, 30 or 50 bonus spins. During these spins, the win multiplier can rise to x5. The highest possible win is 50,000x your bet.
