Feed the Grinder

Welcome to the ultimate idle grinding experience.
In the center stands your Grinder.
Around it? Valuable ores spinning endlessly.
Hold your finger to break the ores.
Send the crushed pieces into the Grinder.
Turn stone into cash.
But not all ores are equal.
Some are common.
Some are rare.
Some are tough, massive, and worth a fortune if you can break them.
The more you grind, the more you earn.
The more you earn, the stronger your Grinder becomes.
