This page was done for those of you who would like a fast answer.  These are my suggestions to try.  I have broken it into five sections. The Boat,  Cable Car,  Masques Chateau,  After Urf Dies, and  Through The Door.  You can scroll down to the section you are in and see if the question you have is answered here.

  

Two suggestions I strongly recommend:

1). Save several games at a time, this way if the game freezes on one, you have others to try.  Do not override all the games.  You can always go back and delete some later if need be.

2). Do not rush the game, let the game make its full move before clicking to do something

 

These are the most common asked questions on the boat.  

How do I get into the door that is locked with the combination lock? 
 

How do I get the three artifacts (pins)?  You will get one when you pick up the puzzle box. The others will be in the vase Mrs. White drops.

How do I get Mrs. White to drop the vase?  Have Urf teach you a magic trick. Show Sabata the magic trick, he will enjoy the trick and will draw you a picture. Go up and see Mrs. White, she will drop a vase. Move the broken pieces of the vase and you will find two pins.

How do I get in to see the captain?  Once you have gotten the puzzle box, three artifacts and a gear go up the stairs to the door. Go down into your inventory bar, do this first step inside the inventory bar. Drag the pin that is next to your puzzle box over to the box (it should light up) click on it. This should cause the puzzle box to appear on your screen.  Now go down and drag that same pin you just used up to the puzzle box again and click when it lights up, .  Now go back down into inventory and drag the pin  to the left of the two pins together up to the key hole on the puzzle box then click. Now go get the last pin and drag it up to the key hole on the box and click. Another compartment will open up and you will find a special key that you can use to open the door.

HOW DO YOU WORK THE CABLE CAR?

HINT: If you have moved a lot of the levers on the control box before you found the instructions and the game won't move forward try and reset the controls. ( switches on right and left pointing down, both levers in middle) then back away and try again. This time only click the ones the instructions say to.

I talked to Green.

Went in to the cable car house and went to the cabinet that has the guest book on it. Inside the cabinet I gathered the fuel tank, funnel and flashlight.

Went to the gold tank by the front door, dragged the funnel up to the tanks lid and clicked. I then dragged the can up to the funnel and clicked.

Went into the cable car. Used the flashlight to look around inside. Found the instructions and pieced them together.

Went out of cable car to the control panel that is up from the fuel tank. Clicked on the three switches on the left. Pulled the right lever as far to the left as it would go.

At this point the game made its move and loaded all the players and me into the cable car.

On the control panels inside of cable car I moved the lever on the left once. Then on the lever to the right I moved it up and down till the green light flashed. I then moved it as far up as it would go.

When the car gets stuck on the ice, just move the lever on the right up and

MR. GREEN'S RIDDLE:

Since you start in the dinning room you might as well start with Mr. Greens riddle.

To find his jewel go into the kitchen to the cold room. Inside of the cold room you will see a freezer, go to it and open it. Pick a tray and take it back out to the kitchen. Go to the stove by the cooper pot. Drag the ice tray out to the pot and click. Turn the burner on by clicking on the stoves knob. The flame will come on and the pot will tilt. If the jewel is not in that ice tray, turn the stove off and go get another tray. Do this until you have found the right one. The jewel will be easy to see when you do get the right one. Then take it to Mr. Green and give it to him.

MRS. WHITE'S RIDDLE:

To get Mrs. Whites riddle you must talk with her and hear her dream. Go upstairs to Kell's room and ask her to interpret the dream. Then go back and tell Mrs. White. Now she will tell you her riddle.

The jewel is hidden in Kell's room inside the chest of drawers.

On the 1st row click on the 3rd column drawer.

On the 2nd row click on the 1st column drawer.

On the 3rd  row click on the 4th column drawer.

On the 4th row click on the 2nd column drawer.

Now click on bottom drawer. Let the pearl roll and come to a stop before clicking on it. Take it to Mrs. White and give it to her.

MS. SCARLET'S RIDDLE:

To get Ms. Scarlet to give you her riddle go downstairs to the dinning room. In the far left fireplace down in the ashes you will find a picture. Take this picture to her and ask if she knows who it is, then ask her for her riddle.

The cat is in the room with Plum. You must click in the order of her riddle.

Make this cat go blind in the brightest light. Make it's leg twist to the right. Make all it's scent for it disappear. The jewels revealed when at last the black cat can no longer hear.

Now follow the red beam to her jewel.

MRS. PEACOCK'S RIDDLE:

To get Mrs. Peacock to tell you her riddle go talk to Col.Mustard. He will tell you some gossip about Mrs. Peacock. Go tell her what you heard then ask for her riddle.

Her riddle is the maze game found in the room with Urf and Popov.

This one is tricky. To help guide the ball put the glove on the ball and click, while still holding down the mouse button move a small distance away and let go of the button, the ball should roll to you. On the holes where the ball is determined to go put the glove on the ball click and pull away from the hole it is rolling to. Do this often and quickly. On the very last hole in the maze, I put the glove on the ball and went a little more than half way up on the right hand wall and let go of the mouse button. Then I did the same thing but this time to the left hand wall. Kinda like you bankshoot in pool.

The ball starts out in the top left area. When I say gray hole, red hole, or dark gray hole, it is the holes in this area I am referring to.
 

COL. MUSTARD'S RIDDLE:

To get Col. Mustards riddle, you must learn a magic trick from Urf and show Sabata. Col. Mustard will walk up when you do this and tell Sabata what to draw.

On the rebus you have a beacker, a clock with hair, and a apple core.

My theory on what the pictures mean is this: The beacker if you count the marks by two and add the half mark will equal 8 1/2. This is where you should set the hands of the clock to. The clock with hair, stands for the clock in the center hallway surrounded by the hairy lions. The apple core stands for clicking on the core (or center of the clock). After you set the clock to 8:30 click on the center of the clock, the face will rotate around and you will be given Mustards jewel. Something drops out but don't worry about it.

To get Plum's riddle you must first talk to Popov, she will instruct you to find a pendant and bring it to her. You can find the pendant if you go stand next to Plum and turn to your left. The pendant is on the bust. Take the pendant to Popov and she will teach you how to hypnotize people.

Now go to Plum and ask him if you can hypnotize him, close the notebook, drag the pendant up to him and click. The pendant will open up. Put the top bar of the chain anywhere up near his face and then gently move your mouse back and forth till the pendant gets into a good swing. Move it just a hair up and let go. In a few seconds Plum should go into a trance and tell you his riddle.

His jewel is hidden in the Iron Maiden. You can find the Iron Maiden out in the hallway to the right of the door you went in to see Plum.

You must click the white buttons in a star pattern. I started with the top left button, down to bottom button,  up to top right button, down and over to middle left button, over to right middle button, then back up to top left button.

Once all the jewels are found and given to the players the game should take over and Urf should perform his great Illusion. If nothing happens go into the magic room and see if that will start it.

Go talk to Popov. She will tell you to go find the ouija board. Go to the dinning room and get the ouija board out of the china cabinet and take it and give it to her. Follow her to the dinning room. Spell out all the players names that had a riddle and Popov name.
 

Masque will appear and take all of the jewels. Now it is time to start talking to people again.

When you get through the locked door, you enter a game room. Go through the room to the door at the other end. In the second room (which looks exactly like the first room) go over to the fireplace. Click and drag the fire irons as far to the right as they will go. A secret passage way should open up.

After you go through secret passage way, you are in a hidden bedroom. Go over to the desk and read the book. A lot of the story is revealed. You can turn the pages by clicking on them. After you have read the book click on the left hand drawer, inside are all the jewels. Click on them and they will appear in inventory. Now over to your left is a double set of doors. That is your next step.

The door with the bomb on it. Use the knife you have in inventory to cut the wires. I believe this is the order. red, orange, yellow, green, blue, top purple, bottom purple. I will not swear to it but I think once when I played the game the door blew up but the game gave me a second try. Now the last time I played where ever I put the knife, the right order cut itself. Except for the last two purples.
