About this quiz
The counting game played round a table, moved to a grid. The mines with a 7 in them are easy to see; the multiples such as 42 and 56 are the ones that end games.
- There are 16 mines: the ten multiples of 7 up to 70, and the six other numbers that are written with a 7.
- 7 and 70 are mines twice over.
- One wrong click ends the game.
