Remember Hedgehog Launcher? Good, because MegaDrill is that in reverse. Rather than fling a hedgehog into space to collect coins dangling from the sky, MegaDrill gets you to plough into the ground to collect coins lodged in the Earth’s crust.

And rather good it is, too. MegaDrill gives you 25 goes to dig into the ground, then upgrade your machinery, then dig again, then upgrade again, until you’re able to dig so deep that you can collect diamonds as big as a house. Worth playing this one until the end, too, just to see the weird animation when you complete it. To our knowledge, MegaDrill might be the only online game in history to show a cut-scene of you paying a percentage of your earnings as tax.
