Understone: Gemstone Mines
Minesweeper where each number sums nearby mining costs
The verdict
Classic Minesweeper tells you how many mines touch a square, while Understone shows the total mining cost of the 8 tiles around it, so every dig is weighed against your stamina. You collect gems for experience, eat food to recover and trade finds at camp for supplies or gear, and later districts add lethal mines. The first 3 floors and camp are free, and $9.99 once opens the rest of the 24 floors.
