Even if there's a 25% chance at any time that one of the 4 shells has the ball under it, placing chips next to a shell can change the complextion of the probability. For each shell lifted, either one of 2 things happen, no ball which means the game continues or ball meaning the player either wins or loses depending on the chip placement. Sometimes, I wonder if Bob Barker actually "felt" the ball inside the shells as he shuffled them.

Every time I saw the Shell Game, Bob narrowed it down to two shells this one you win, this one you don't; no matter how many chips the player started with; 1, 2, or 3.
So I thought it was obvious he knew where the ball was.

If you notice on the Shell Game, the "shells" are lined with some type of foam rubber material -- enough to muffle the ball noise hitting the sides of the shell when they are moved around, but the ball still can be felt hitting the sides by the host to ensure that they keep that shell in play to the end, if they so desire.
