Author's note- How do I play Boulderdash?
Collect the diamonds, and avoid the falling rocks!
Along the way, you'll encounter these elements:
| Titanium Wall | An indestructable wall |
| Dirt | You can dig through dirt, leaving empty spaces |
| Brick Wall | This wall can be destroyed if, say, you blow up a firefly next to it |
| Magic Wall | Just as destructable as the Brick Wall. If you drop a rock into the Magic Wall, it turns into a diamond. If you drop a diamond, it becomes a rock. There has to be an empty space under the Magic Wall, or else the falling rock or diamond will be swallowed by the wall and lost forever. |
| Firefly | Moves clockwise. If you smash it with a rock or diamond, it explodes. Deadly to the touch. |
| Butterfly | Moves counterclockwise. If you smash it with a rock or a diamond, it explodes into diamonds. Also deadly to the touch. |
| Amoeba | Grows randomly. If you suffocate it so it has no place to grow, all of the amoeba will turn into diamonds. Amoeba is not deadly to the touch (so you can help suffocate an amoeba by standing next to it), but will kill fireflies or butterflies that touch it. |
| Closed Exit | When you collect the required number of diamonds, this will turn into an Opened Exit. |
| Opened Exit | Passage to the next level. |
At any time during the game, you can press [ESC] or hit [Restart] if you become hopelessly stuck. If you hold the [Shift] key while moving in any direction, you will affect the element in that direction without actually moving there. Therefore, you can clear dirt, move a rock, or collect a diamond while standing still.
You may move to the previous and next levels using the buttons provided, but your score will only be permanently recorded when you successfully complete a level.
