The answer to my puzzle is 8605. Start on the number 5711 and follow the arrow directions. If you start on another number, you'll end up heading in a direction that doesn't contain a number.
Hmm. Not sure what you mean by the 1000 remark...
If you enter the correct combination going left to right, you will trigger the trap if you don't go backwards for the first number or touch the other sliders first.
This is exactly why I loathe most puzzle designs--they simply do not contain enough information to "properly" solve them where you've even got half a chance of doing so without getting pummeled.
Here's what I mean: The way I think, you could end up with any of those numbers. Why? Because with the information given, there is no indication that the arrow directions cannot "edge wrap" back around to the prior column or row.
If there was another earlier clue/reference to the puzzle/chest, say perhaps with a pirate-y quotation about, "One should never wander off the edge of what is written on the charts, for there lie beasts and bombs and all manner of evil ilk." then I would at least have a shot.
My 2-pence worth...
