Our Review of Jack Hammer 4 Casing The Dragon
The highlight of Jack Hammer 4 Casing The Dragon is its High volatility, with the potential for some high payouts if you are the lucky one. Its bonus rounds might have had more to offer, but what is here is ok. A small bet size of £0.2 places it among the lower-minimum slots you can find online when comparing minimum bet size and potential big wins, and an RTP of 96.03% is standard for most slots.
Additionally, the theme and sound effects could have been a bit more unique, placing it among the less distinctive options from Netent, which you can play directly on most devices.
