New exciting versions are also available. Please check www.boulder-dash.com.
Scenario

Chances
Each player starts with 3 chances. Bonus tries are awarded after every 500 points. The tunnels created by Rockford will “shimmer” when you are awarded a bonus try. A bonus is also earned by completing a Playable Intermission If you get stuck with no way out, you can restart a level by pressing button A, but it will cost you one of your tries (referred to as ‘MEN’ in the game itself).
Scoring
The current point value is shown on the top-left of the play screen, to the right of the picture of a Jewel. The number of points per Jewel changes. The point value is determined by the CAVE, Difficulty Level, and bonus status. The bonus value occurs after the required number of jewels have been collected. Every 500 points the tunnel will sparkle for a moment and you get another Rockford.
You also score 1 bonus point for each second of time remaining when you exit the CAVE.
Playable Intermissions
There are 4 short interactive puzzles which you are entitled to play after completing CAVES D, H, L and P. There is no penalty for not playing or losing the intermissions. If you complete a Playable Intermission successfully, you receive a bonus Rockford.
Game Elements
| Name | Description |
|---|---|
| ROCKFORD | This little fellow is the ‘star’ of the game. Rockford has the power to dig through the earth and collect Jewels. If he digs under a boulder and doesn’t stop, he will not be struck and the boulder will drop down into the tunnel. He can push single boulders horizontally, if there is nothing to block their path. Rockford can stand directly under a boulder without being crushed, but if a boulder or Jewel falls on him you will have to start again |
| Boulders | The rocks will fall whenever gravity dictates. They will fall straight down if unsupported, or they will topple off underlying objects if there is nothing to block their way. Experimentation is the best way to learn the “physics” of Boulder Dash |
| Jewels | You must collect the required number of gleaming diamonds in order to exit one CAVE and advance to the next. There are many ways to create Jewels. For example: transforming Butterflies, suffocating Amoebas, or dropping boulders through an Enchanted Wall will create additional Jewels. When the proper number of Jewels have been collected a flash will let you know that the escape door is revealed and open |
| Fireflies | The deadly Fireflies glide about in the tunnels. Their behaviour is predictable; they move along the edges of all the exposed areas. This is a help, since they will explode on contact with Rockford. Turn the tables by dropping boulders on them, which causes them to blow up. This comes in handy when you want to demolish a wall in order to get some Jewels |
| Butterflies | The colourful Butterflies behave much like Fireflies. However, they fly in the opposite direction of the Fireflies and they turn into Jewels when they explode |
| Amoeba | The Amoeba is a green blob that bubbles and grows through earth and air. Rockford can touch it without harm. Fireflies and Butterflies will explode on contact with the Amoeba. When Rockford surrounds the Amoeba with rocks, it runs out of growing space, suffocates and turns into Jewels. However, if the Amoeba grows too large (about 200 squares big) it will die and turn into boulders |
| Enchanted Wall | The Enchanted Wall looks like any other wall, however when hit by a falling boulder it begins to vibrate for a limited time. During this period, any boulders that drop through it are magically turned to Jewels, but only if there is space below the wall. It will also turn Jewels into boulders if they drop through it. Once the enchantment phase is complete, it cannot be reactivated in the same round |
| Titanium Wall | The exterior wall is an indestructible boundary to play action. Rockford can only exit to the next CAVE through the escape door |
| Escape Door | Initially the Escape Door looks like a portion of the Titanium Wall. After Rockford has collected the required amount of Jewels, it is activated and begins to flash. At this point the mysterious escape door is revealed and you may exit, providing time doesn’t run out |
| Time | each CAVE is timed. When time is running out a warning sound will occur |
Strategy/Tips
| Name | Description |
|---|---|
| Rockford | Rockford can affect an object that is next to him without moving into it. Keep FIRE pressed and move the Joystick in the direction of the object or earth you wish to affect. Rockford will not move, but the object will react |
| Boulders | You will often find yourself digging or moving downwards only to find a boulder has been toppled by your movement and is about to land on you. The only way to avoid losing your man in these situations is to move quickly to the right or left, out of the boulder’s way. Rockford runs as fast as a boulder falls, so it will never catch up to you, unless you hesitate or stop |
| Exit | When Rockford has collected the required amount of Jewels for the CAVE he is in, the Exit is revealed. At this time you should decide whether to go for bonus Jewels (at a higher value) or to exit for the time bonus point (1 for each second remaining). Make sure you know the location of the escape door and you can get to it before time runs out |
