This is based off from Mario Party 10's Bomb-omb Bogey.
The location of the map is inside of a cave full of crystals.
Players must mine crystals and avoid mining bombs with the choices of using either the spacebar or mouse for 60 seconds. The bombs spawn at random times, so there is no clear pattern.
Mining the crystals will give you 1 point. However, mining the bombs will cause you to lose 2 points. The three players with the most points will win.
- Crystals do not spawn more than 4 or 5 times in a row.
