Earth Shaker is a Boulder Dash-inspired game published as a cover tape in 1990 in Your Sinclair (for the ZX Spectrum 48k). Notable in being the first covertape to subjectively set a high standard,[1] having been initially rejected by publishers Zeppelin because of First Star's suing of companies publishing Boulder Dash clones.[2]


Originally conceived as a Boulder Dash clone by Michael Batty, but its scope grew through a long development process:

"I started Earth Shaker about 4 years before it appeared in Your Sinclair. A Boulder Dash clone seemed like a reasonably easy thing to program. I thought Boulder Dash was great and played it for ages. I'm still fascinated by the way you can get such complicated behaviour and realistic avalanches by using a few simple rules. Earth Shaker just grew - I kept leaving it and going back to it. But it was the first machine code game I managed to actually finish."
