I just got this random event.

 

 

 

Is it new or rare enough not to show previously for me?

 

 

 

And also I would like to know what is reward like if you do it correctly? I rushed and i failed to complete it

What it does:

 

 

 

While you're raking your plot or tending to your crops, a pirate will tell you about some treasure that's buried in the patch where you're growing your crops. He asks you to help him get the lid off the treasure chest by solving the combination lock puzzle, and he'll share the contents of the chest with you.

 

 

 

What you should do:

 

 

 

If you ignore him, he'll mug you and teleport you to a remote location. Possible rewards include gold coins, a gold necklace, a gold ring or a gold bar.

 

 

 

If you decide to help him, you'll get a puzzle screen. To solve the puzzle, all you have to do is match the centre row of pictures with the correct words, using the arrows like a slot machine. When you're done, click the "unlock" button.

 

 

 

This?

 

 

 

Not a new random event. At least Jagex did not introduce any this week.

It's been around since 2005. It only happens while farming, I think only at allotments, but I'm not sure. I've only gotten one since farming came out, but I think the rewards are just your average random event rewards.
