Minefield Retro is a logic-and-strategy game that imitates Microsoft's 1990 Minesweeper. Its board features silver-gray tiles that cover white tiles. Each hidden white tile represents open water. Round, spiked black icons on 10 white tiles represent underwater mines. Some tiles are also labeled with colored numbers that alert the player about the number of spaces between the spots and the nearest mine.
The player starts by selecting one of three difficulty levels displayed as mine icons. In ascending order, each icon represents a grid of higher tiles and spaces (8x8 grid, 16x16 grid and 16x30 grid). On the board screen, a digital display near the top-left corner notes the number of mines that remain hidden at any given time. The digital display to the right of a central yellow smiley face icon is a clock that times how long it takes for the player to win or lose the game. The player can reset the game at any time by selecting the smiley icon.
To win the game, the player must only select silver-gray tiles that don't cover mines. If the player accidentally performs a virtual detonation, as depicted by a black mine on a red background, all mines become visible. The smiley face also turns orange and frowns with disappointment. The player must then select the emoji to try again.
It's important to note that Minefield Retro automatically enlarges the screen after the player selects a difficulty level. Additionally, the game offers a hint tool at the top-left corner of the board's frame.
