· The robots
There are 3 kinds of robots that you can control to solve a map.
These 3 robots can be destroyed and can be pushed.
To switch from one robot to another (Grabber, then Zapper, then Pusher), you simply need to press Enter.
To move the selected robot, use the arrow keys.
To make the selected robot do stuff, press the space bar.
The robot Grabber can be directly selected by pressing the key 1 on the numeric keypad.
The principal role of the robot Grabber is to collect the Klondikes on a map to assure the success of the mission.
It can also use other objects:
- It can set the timer on time bombs,
- It can teleport itself in the place of teleporters,
- It can turn turnable reflectors.
Note : the robot Grabber does not need to be close to the objects to use them. It only needs to have a direct line to the object to use it.
The robot Zapper can be directly selected by pressing the key 2 on the numeric keypad.
This robot can destroy destructible objects, however far away they are, thanks to its invisible laser ray.
Note : laser rays can be deflected by reflectors and converted in push by convertors.
The robot Pusher can be directly selected by pressing the key 3 on the numeric keypad.
This robot can push movable objects, however far away they are, thanks to its push.
Note : a push can be converted into a laser ray by a converter.
Here is a table explaining the possible actions the 3 robots can have on different objects:
The monster is a particular robot that you do not control.
It cannot be destroyed and cannot be pushed.
It is inoffensive and heavy enough not to slide on ice.
All it does is walk forwards without ever stopping, with a constant speed defined by the author of the map.
If the monster meets an obstacle, it turns around and retraces it steps, until it meets another obstacle, and so on...
Note : there can be more than one monster on the same map, and they will all have the same initially defined speed.
· Construction elements
Wall is impenetrable, indestructible and immovable.
Stone floor is destructible.
If a bomb or mine explodes on or near a stone floor, these ones, impacted by the explosion, are destroyed and leave an empty space behind.
Note : stone floor tiles protected by an indestructible object are not destroyed in the explosion.
Broken Stone Floor
Broken stone floor is destructible.
It has the same properties as normal stone floor.
Furthermore, broken stone floor only supports one step.
It breaks down and leaves an empty space behind if an object that it supports moves or is pushed away from it.
Bronze floor is indestructible.
Any robot walking on ice will slide in the direction it is moving in, until it slides off the ice, or meets an obstacle.
The same thing will happen to an object pushed onto ice.
Furthermore, while sliding on ice, robots are unable to turn.
Note : ice tiles impacted by an explosion of a mine or a bomb will melt and leave a bronze floor tile behind.
Where there is no wall, no floor, no ice, there is a hole.
Nothing can step or be pushed onto a hole.
More, thanks to a fine edge, nothing can fall down in a hole.
· Goal elements
The two goal elements of the game are Flags and Klondikes.
On every map, your mission is always the following:
- collect all the Klondikes,
- destroy all the Flags.
The number of Flags and Klondikes varies from map to map.
It can be between 1 and 299.
Note : some maps only contain one kind of objective elements (Flags or Klondikes).
All Klondikes, without expection, must be collected by the robot Grabber.
Note : once taken, a Klondike is definitively collected (even if the Grabber is destroyed afterwards).
The Klondikes can be pushed and can be destroyed.
If a Klondike is destroyed, your mission will immediately fail.
All flags, without exception, must be destroyed.
Contrary to Klondikes, flags are fixed and cannot be pushed.
Note : there are many ways to destroy a flag (with the robot Zapper, with a zapping cannon, a mine...)
There are 3 kinds of blocks.
All blocks are movable and can be pushed.
It can be destroyed.
Note : as a general rule, all stone-coloured objects can be destroyed.
It cannot be destroyed.
Note : as a general rule, no bronze-coloured objects can be destroyed.
It cannot be destroyed.
Like a mirror, this block reflects laser rays back to their source.
Attention : if the robot Zapper fires at a diamond block, the Zapper will instantly be destroyed!
There are 2 kinds of reflectors.
The reflector is an object that deflects laser rays at a 90-degree angle, if they arrive at one of its deviant angles (example: from the west to the north - and back again - to an opposite reflector).
It is indestructible and can be pushed.
The turnable reflector has the same properties as the standard reflector.
Furthermore, the robot Grabber has the possibility to turn a reflector a quarter turn, as many times as needed.
There are 2 kinds of explosives.
These 2 explosives can be pushed and can be destroyed by a laser ray.
The mine is a sensible explosive that explodes if any kind of object touches any of its 8 sides.
As well as that, the mine explodes if it is pushed next to an object or a wall.
Note : the edges of the board are not considered walls.
The explosion of a mine happens on 9 points with the central point being where the mine was located at the time of the explosion.
The time bomb is not sensible to objects touching it.
However, it can still be destroyed by a laser ray.
This explosive has a timer of 5 units (from 4 to 0 inclusive) that can be set by the robot Grabber.
After 5 units of time have passed, the bomb explodes on 9 points with the central point being where the bomb was located at the time of the explosion.
Note : the units of time duration is defined by the author of the map.
· Atomic elements
The teleporter can be destroyed but cannot be pushed.
It allows the robot Grabber to teleport itself.
It can only be used once: after the robot Grabber has teleported itself in its place, the teleporter is destroyed.
The convertor is indestructible and immovable.
It converts laser rays passing through it to pushes, and the other way around.
Note : the convertor has a direction (north/south or east/west). Laser rays or pushes passing through it in the right direction are converted.
There are 2 kinds of cannons.
No cannons can be pushed.
Each cannon can either be fixed or rotate.
The rotating cannons rotate clockwise in an automatic manner.
Note : the time a rotating cannon takes to rotate between 2 positions varies from map to map, defined by the author of the map.
These cannons can be destroyed.
The zapping cannons continuously shoot invisible laser rays.
Note : the laser rays can be deflected by reflectors and converted by convertors.
These cannons cannot be destroyed.
The pushing cannons push continuously.
Note : a push can be converted into a laser ray by a convertor.
