Floor. Doesn't block anything.
Wall. Blocks everything.
Water. Turns into Dirt when a Movable Block is pushed into it. Chip drowns in it if he doesn't have swimming flippers. (There are no flippers available in the current puzzle). The Glider monster can fly over it (but other monsters, not in this puzzle, can't).
Dirt. Blocks everything but Chip. Turns into Floor when Chip walks on it.
Exit. This is what you are trying to reach. The game is over and you win if you can get Chip to this square. There may be a limit in the number of moves you have to reach the Exit.
Red Door. Blocks everything but Chip and Chip needs a Red Key to get through the door. Once Chip "opens" the door, it turns into Floor.
Yellow Door. Blocks everything but Chip and Chip needs a Yellow Key to get through the door. Once Chip "opens" the door, it turns into Floor.
Red Key. When Chip steps on it, it is moved to the "Resource Box" to the right of the playing area (and is replaced by Floor). Chip may (but not in the current game) have more than one Red Key at a time but each Key is used up when Chip goes through a Red Door. (To go through three Red Doors, for example, Chip has to get three Red Keys.)
Yellow Key. When Chip steps on it, it is moved to the "Resource Box" to the right of the playing area (and is replaced by Floor). Chip may (but not in the current game) have more than one Yellow Key at a time but each Key is used up when Chip goes through a Yellow Door. (To go through three Yellow Doors, for example, Chip has to get three Yellow Keys.)
Toggle Wall turned on. Acts like a wall except that anything on it at the time it is turned on is still there and can move off the Toggle Wall. (In particular, if the wall is turned on while a movable block is over it, the block stays there but can be pushed off it by Chip although Chip doesn't move into the space formerly occuppied by the movable block.)
Toggle Wall turned off. Acts like Floor.
Green Button. Whenever Chip or a monster or a Movable Block moves on top of it, it changes the state of any and all Toggle Walls in the puzzle. Any that are turned on get turned off. Any that are turned off get turned on.
Movable Block. Can be pushed around by Chip. Blocks monsters. Turns into Dirt when pushed into Water (or the Water becomes Dirt and the block vanishes).
Chip. Shown on the left as facing South. Can face in the other three directions (faces the direction in which he moved to get to the current square). You have to move him to the exit after collecting whatever you need to get there. Drowns in Water unless he has flippers and is killed if he encounters a monster, a fire (not in this puzzle) or a bomb (not in this puzzle).
Chip in Exit. The only foreground image that can't be moved because it indicates that the game is over and that you won.
Click on Chip (shown with a blue border in the chart to the left) to stay in the same spot for one move (to wait for an appropriate condition for moving).
Click on one of the squares above Chip (shown with a red A and red borders in the chart to the left) to move up.
Click on one of the squares to the left of Chip (shown with a green B and green borders in the chart to the left) to move to the left.
Click on one of the squares to the right of Chip (shown with a green C and green borders in the chart to the left) to move to the right.
Click on one of the squares below Chip (shown with a red D and red borders in the chart to the left) to move down.
Squares that are equally far from Chip in both horizontal and vertical directions or farther away vertically move Chip vertically. Squares that are farther away from Chip horizontally will move Chip horizontally.
